I took some time off from shop cleaning when I uncovered my 153. I had a couple of things to check on. #1. Would my plan for using the stock fuel pump port for my oil filler & breather/draft tube work? It will with some fitting. #2 Will I be able to use the stock Chevy II dip stick location with my rear sump pan? No I can not. I have a fixture for mounting a dipstick on the pan but don't know if there is room on the right behind the starter or on the left tangled in with the exhaust. I think my pan may be from a Mail Jeep. Does anyone with a rear simp pan have a solution? I could mount the fixture on the side of the block if I can clear the cam.
Good information here. Been cogitating and ruminating over the possibility of using one of these in the Whatever project. Anyone in upstate New York near Saratoga have one of the mercury marine engines in usable rebuildable condition they'd like to part with, let me know either dm, or in the Whatever project thread. Thanks...
These will bolt into any place a small block Chevy will & likely be fun in your build. Check out all the boat shops & marinas in your area. A 181 would be a good find. MerCruser, Volvo, OMC. Also check out shops or yards with lots of fork lifts. Now you've given me 2 new threads to check out.
Building one for a nostalgia dragster right now. for my build, I made a 6bolt adapter plate to bolt to the head so that I could separate the exhaust flanges and the intake flanges. The intake flanges are aluminum so that I could weld VW-Webber intake manifolds as the runners
One thing I like best about these Chevy 4 threads is how everyone solves the scarce aftermarket parts problems. That is cool!
I picked up 5 3.0's today for 100 bucks. I could of got another one but felt I had my little S10 truck overloaded as it was. 3 are Mercruiser, 1 Volvo and 1 OMC. two of them are stuck and two are one piece rear seals. I liked dreracecar intake and I have a VW weber intake, so I needed to get a 3.0 but settled for a truck load! I have the 3.7 engines so will play with these to.
A friend had a dragster with 2 153s in line that ran from one V8 distributer. You could be a mini-Tommy Ivo!
It was a 100 mile round trip to get them, driving along thoughts of 4 of them behind the cab of my coe..... naa, that would look stupid.... but maybe not!
I know you guys have been over this a hundred times in other threads. But, in stock form, is a 181 cylinder head better then a 153 head? And the specs I have found for the 181 Mercruiser camshaft are .440 lift and 208* at .050. Do they sound correct? Hope to have my 153 apart today and see how bad the Mail Jeep beat it up. Thanks, Gene.
I think there are at least 3 181 heads & two have 8 ports. One of these is better but the both have the potential to be better than siamesed intake heads. That said I don't know how much better or if it matters for a street driven car. Individual ports would be an advantage for tuned port injection. Anything that can be done to the siamesed six cylinder heads can be done to the four. When I sat down with Steve Tanzy at Erson Cams before they moved back East he came up with 3 profiles for my roadster. I cost the hottest of the 3 which may not have been the best choice for my REAL world use. I had the BBC 1.70 roller rockers so he used that ratio for the cams. I now have a set to the proper 1.75 roller rockers. Lucky for me when the cam came the card gives the 1.75 specs. Here are both sheets tom compare. I don't think it will matter a lot.
I have a buddy the has a boat parts yard. He has a few marine 181's for parts. And as usual with me, I'm trying to do a little more with a little less. That's why I was asking about the heads and cam. And I think I quoted 208 degrees, but I think it's 204 for the 181 cam vs 192 for the 153 cam. Gene.
Gene, There are I think four threads on this site about these engines. Too much of it is misinformation and some of that is mine. There is some discussion about using boat cams which some say are designed to run at a steady high rpm. I don't know if that is really and issue. That is why I sat down with an expert and discussed my build and what I planned to do with it. I was lucky to be able to do that, just walk into a major outfit that was grinding cams one guy/one cam at a time back then. At the beginning I wanted to use as much off the shelf stuff as I could knowing that some parts would have to be sorta' special. Really I don't understand many of those cam numbers.
I haven’t posted here in years, but this thread popped up while I was refreshing my memory on these little engines. I always enjoyed this thread, and the others about these little guys. I currently have two of them. Im building a header for one now.
Hey Mr. Count...what intake is that?? Not as nice as yours, but I'm working on a header also. It's off a 2.5 Jeep...I think I can make it work without too much trouble. Gene.
I'm not sure what plan I'm on here...way past A,B or C...more like H,I or J on this little motor. Decided to go back to the 1st gen, Iron Duke head and the rebuilt 153 +.060 short block with the Racer Brown reground 210*-.500 cam. Played with my new die grinder a little on the head and made an adapter out of a carb spacer for the intake. Still undecided on making a header, but the Jeep header will not work with the Pontiac Sunbird intake. Gene.
My 29 RPU with a 181c.i. Chevy II banger with a straight pipe. Hopefully the YouTube Link will work, and not jerk YouAround too much.
I thought the "2" meant a 2-cyl. Chevy engine being here lately. It's probably more a "banger" than yours -- yours is a fine choice! Maybe Chevy II would be a better name.
I used a 1981 Pontiac 151cu/in with a Crager adapter to a 35 transmission. I used a Hurst style mount, that I modified and a mid motor plate, between the engine and trans.
A Google Account is the first step for you... if you have a Gmail address... you already have a google account. It is easy to get, does not cost a thing and works better than yahoo or any other email services. Hello, Here is a step by step way that is simple and I have used it hundreds of times when a movie I have taken with my digital camera is uploaded to my laptop. From there, you have the basic starting point. Don't try to do this on a phone or tablet as it is too difficult to access that film you took and saved to your computer or laptop. Also, edit your film first on your laptop as a clean film without non-sensical additions of a lady walking on a street is added to a film on a 32 roadster driving down the street. Easily edit or cut out those parts to make a clean moving movie. If you can remember, don't talk while filming or at least edit out the sounds. Unless, of course, you are filming a hot rod sound accelerating, etc. This is the photo that is saved on my laptop, directly uploaded via a memory card from the camera. Recently, I was going to make a film to go along with a story I was writing. So, to make it easy for anyone to use previously uploaded and saved film from anyone's computer files, I made a simple step by step, as to what shows up and what to select for a You Tube video. The finished product can be copied and posted on any website, direct email to anyone, or saving the link on your phone, tablet or laptop for viewing anytime, anywhere. You Tube is rather simple. Back in the 2015 days, I had no clue as to what to do. So, I plodded along with a scrap film I had saved. I had to create a channel first. J NAKI so, now I can follow the simple instructions step by step on the screen. Once you have created your page, then click on the red highlighted box +. That goes to the next screen to up load your film file saved from your files in MP3 or mp4 style. Those are best to save and use. Now, you are ready to upload your saved film. This screen shows the next step. Select your film from your files and copy/drag it to the arrow screen and it will start to upload to their studio files. If it is not an approved movie file, MP4, as you try to upload it, the screen will tell you it is an invalid file. Make sure it is a MP4 file. This new screen is important. If you check "not for kids," then the process moves on to the next screen, if you check Yes it is for kids, then it is another whole set of screens, etc. Just check not for kids and everyone can see it finished. I also made my own thumbnail photo, instead of a You Tube generated thumbnail. Once the film is edited on your computer and it is ready, save with a specific title. For sample sake, this one is labeled “Chevy Truck to Finish.” In reality, it certainly looked finished up close. Another section calls for a thumbnail that will be the visual description of your film on any website or your You Tube channel. They automatically find several shots and you select one. Or, you can save your own photo, but make sure it is smaller than 2mb so it can qualify as a custom thumbnail photo. (most digital cameras are shooting in over 6 mb-20mb+ per photo. Most phones also shoot in 5-10mb.) The action you do on the screen pops up another screen telling you of the progress. And/or some type of violation with copyright, like adding music from a popular source, etc. Since most of my films are taken in a silent mode, there is no commercial music added, nor would I want one. It just detracts from the action. Who wants to watch a drag racing video with smooth jazz playing in the background? Or even rock music of sorts? This is where the copyright problems start. If you want people to see the saved video anytime, then check “Public.” Otherwise no one can see it publicly. Now, the You Tube search feature we all use to find a video comes into play. When it is all checked correctly, then this final screen pops up. We do not use any of those links, so, we click close. But we know it is published in our studio parameters. Jnaki The final screen pops up to show you where your video is located. Now, open the film and copy the top information box. The last screen to check is your channel home screen. Click on the video you want to watch. Once it comes on your laptop screen, then copy the HTTPs// address. Now, you can past the link on any website, a direct email to someone or some company to clarify some action. Once posted, it is available for anyone to see directly or it will be located on your You Tube channel. The fun part is that we all have access to the You Tube channel streaming services. So, on your large tv screen, call up your home streaming channels and select You Tube. In the search, type in your You Tube channel name. A large screen with quality sound makes viewing on a really large monitor wonderful. It is almost like being at the drags in person. Sound? Turn up your volume or external speakers for a wonderful presentation. Note: Now that it is on your You Tube channel, where ever you go, you have access to it via a tablet, puny phone screen or a friend's huge wall monitor in his/her viewing room. Sample: When you make your video, copy the top information title: This bit of information is the one you can post on any website that allows video links to be posted. Now, you are an official You Tube creator. YRMV Play the Junior Thompson video. I filmed it in silent mode back in 1959. I found the original Jr. Thompson Studebaker sound on my own LP album from 1959. I digitally copied and pasted it as a soundtrack, matching the film I created. Now, the "Sound" version is a lot more fun to watch. GOOD LUCK and PM me if any additional information is needed.
