Anyone running BB/727 in there 46-48 dodges? I looking for pics and suggestions. I have been hacking away at this and now I wanting to move it foraward a bit. So I want to start fresh with some suggestion from those that have done it. what Rad did you use? what fan did you use? how much did you recess the firewall? Where did you put the rad? Motor mount? what other mods had to be done? Right now I was going to run the clutch fan inside the rad core support. But I could move the engine farward a few inches if I run a electric fan in front, but then you lose 30% of you airflow. I have heard horror stories of overheating.
I am at the tail end of a SBC swap into a '46 sedan. I used a hacked up Hurst mount for the engine, a short water pump with double groove pulleys and mounted a Case tractor radiator (it was cheap and it fit) to the front edge of the original core support. I'm also using a front dump exhaust manifold on the drivers side to clear the original steering box. I'm bolting the front sheetmetal back on today so I'll let you know how it goes. Haven't tackled the fan yet but it looks like I'll have plenty of room.
I have one in a '49, but I don't know how similar the frames or the size of the engine compartments are.
I actually have a fatman stub in mine. The firewall is recessed a bunch. I made motor mounts that used part of the stock 440 mount and ears taht I welded to the frame. The radiator was a recored stock one, but we had some problems with it, mainly due to the quality of the work done by the radiator shop. It now has a walker that's intended for a '41-'47 Chevy. It's mounted in the stock location.
I think there are some pictures of the engine mounts on my old msn groups site: groups.msn.com/smithswayfarer It's pretty hard to get a picture of much under that hood. It's kind of cramped in there, plus it doesn't open very far. I can take pictures, but I don't know how much you can see. On the MSN site, there are pictures as we were putting it together, so it may answer some questions.
Well, not too bad. I had to trim away about half of the battery tray on the drivers side and I had to shim the engine just a bit to get the drivers rear plug to clear the column. My fan isn't going to work tho, it's too wide and hits the edges of the core support. Everything else seems to be clearing tho.
Have you mounted the sheetmetal that goes from your coresupport ot the front of the fenders yet. I would like to see how you trimmed those.
Although, I'm not putting in a big block Mopar in my car ( a ' 48 plymouth--same frame) I AM putting in a small block(318). I had to trim out the battery box but I didn't have to cut the firewall. Gonna have to move the radiator forward and use an electric fan. I put my engine in without removing the sheet metal. I used PlyDo motor mounts. I also found a way to mount a tremac five speed behind it. Not real tough but had to built lots of stuff---throttle linkage, exhaust, and tons of small ****. Had to mount a remote oil filter setup because the starter motor was in the way on the drivers side ---hydralic clutch now mounts on the p***enger side.
I didn't trim anything forward of the core support. My only cuts were the inner fenders basically right above the upper A-arm on each side for exhaust clearance. Now that it's back together I probably didn't even have to cut the p*** side but I did anyway. I'll get some pics to you soon.
my 48 plymouth coupe has a 427 \ 454 which i'm pulling at the moment , in exchange for a 383 dodge i picked up . when i bought it it already had a chevelle/nova front clip installed , there's ton's of room for everything , i guess maybe these guy's were in the same position as you are , & decided it was just too much work, & you wood get p.d.b ' s , just my 2 cent's worth - tommy
to buddy with the 48 plymouth coupe ; you would'nt know where a fellow might find replacement floor pan's , or any in good shape - would ya ? . thank's - tommy
I have a 1946 Desoto with a 440 in it .. I did not recess the firewall , Used a cross flow radiator from speedway, mounted the long way up and down Pictures are hard to take , cause the big old fenders cover most of it
The motor in the wayfarer is far from stock, KB pistons, Crane Cam, full roller valvetrain etc. It's scary fast and kind of squirly. We put an eaton unit in the rear last year, but then screwed up the ******. A new ****** is being built right now with a GV overdrive behind it. It will make the car much more enjoyable on a long drive.
