chevy II 153 four cylinder

This one that 1oldtimer posted looks pretty good, and the price works out to $142 USD, with frete grátis! Presumably only grátis in Brazil though.

Perhaps someone has a friend visiting to or from Brazil...

 

That's nice !

 

Yes they did. Also sweepers Arial equipment and other stuff.

A company called PSI in IL out fitted thousands of 3.0 engines to use in LP AND dual fuel industrial applications.

I posted a couple options last year some time ago.

I'm going to use a set up minus the plenum that basically gives a spot for 2 carbs with a adapter .

 

You could also add dividers to the 153 intakes.

 

Got the one in my jalopy running.
But can't upload the video?

 

You have to put it on YouTube and then paste it into your thread for video. The upload video feature on the hamb has never been functional

 

Looking at that intake and the video I posted. I think the intake the guy in the video built could have a lot smaller box under the carb. I think I might go this route when I build one, if the Brazil ones aren't available to me at that time.

Here's his finished result:

 

I would guess with that large plenum , keeping port velocity & fuel in suspension might be difficult

 

The head, intake and exhaust manifold I used is from a '77 Pontiac Sunbird non-cross flow motor. It had a 2bbl on it factory, so it was an easier jump to a 4 bbl. Its a neat piece with screw in studs, guide plates, decent looking ports, and even a chrome valve cover factory. Gene.

 

Was the '77 Sunbird a 151? What engine are you running?

 

Yes '77 151 non-cross flow and I have a '70 153.
Did find out the hard way I also had to use the 151 head gasket. Couldn't get a stamped steel one, so lost a little compression. Gene.

 

That wasn't a 153 or 181 cu. in engine , different everywhere .AFAIK

 

It looks like the side cover and probably the valve cover are too far gone to save and the block is probably full of water but if they were in better shape it would be worth making a road trip and then cutting the boat up with the sawzall In Eugene Oregon and free if you bring your own trailer.

 

I'm not sure what you mean.
I can tell you I have a Chevy II 153 and PG trans from a 1970 mail Jeep. And a head, intake and exhaust manifold from a 1977 Sunbird 151 non-cross flow head motor. Gene.

 

If I step away from this for a while when I come back I have to relearn it all, well not all just the important stuff. Do you remember what was different with the head gasket? Was it piston size related? I thought the 151s had a change in the order if the valves. Maybe not. The cranks it 151,153,& 181 will interchange. (2 piece seal) The cams will too except the 151 has the distributer gear is a different spot or we would have a roller cam choice. It could still work if we adapted a Ford ignition setup or a mag driven off the front.
Could you shave the head to make up for the Gasket thickness. I thought I had a 153 shim gasket? So would the cross flow 151 interchange?

 

If that's true , what was the reason for the swap ?

 

Six Ball... the 153 gasket didn't block some water passages in the 151 head that really went no where. I had water coming out between the head and block on the outside.
Had to use the 151 gasket to block them.
Only a composition one was available.
And yes I could have taken more off the head, but it was already done.

2old2fast...the 153 head was pretty worn out. The plan was to use a 3.0 head and I do have one, done, but I had no intake or exhaust to fit it as it was a marine piece. By dumb luck, I came across the 151 head and manifolds at a estate sale for $30. I didn't really know what it was until i got it home and did some research. It was in really good shape. It already had screw in studs and guide plates from the factory. The head has small valves, but nice looking ports. And a pretty nice exhaust manifold. Along with an 8 bolt chrome valve cover. The intake was set up for a 2 stage 2bbl so adapting to the 4bbl was easy. According to Comp Cams, the non cross flow head motor uses the same cam as the 153, but I had my original cam regound here locally by Racer Brown. And the motor has normal 153 sizes 3-7/8" +.060" × 3.25" Gene.

P.S. I have the other half of the piston ring set if anyone needs them.

 

Didn't know the heads interchanged , thanks for the info .

 

I didn't know that either. I'll have to do some more comparisons. I have 2 151s. One from a a Skylark I think, professionally rebuilt cross mount front wheel drive. It is no a cross floe head. Don't know why I have it. The other is from a 1980 Jeep with 60K miles. It was a take out and was replaced by a small block Chevy. It is cross flow and 100% complete. It will find its way into something. I need to study the heads and take a closer look at the water jackets. These are fun engines.

 

The 151 engines had a 4" bore and 3" stroke, they were 1/2 of the 302 Chevy V8, thus 151 cubic inch. There is some interchange between the early 153 and 151, but not much that would be beneficial....

 

Half a 302, even at that, that Z/28 will still haul ass!

 

I’m getting ready to convert a 153 from Mercruiser to automotive so that my Model A frame has something not cookie cutter. I’m a boat guy so I have an extra 153 and a 181. Thinking about swapping the 153 head onto the 181 but I’m not sure yet. The 153 I have is an early one with the finned valve cover so it’ll look sharp. I just scored a Clifford intake.

does anyone have a close up of engine mounts? I’m thinking the burst mount may be the way I should go. I’m going to run an old 3spd most likely. I have a bell housing somewhere in my stuff that’s in storage so I can put it all together. And the drop out center GM rear end that I have won’t break with 100hp

 

That sounds like what I have in my AVATAR. You are welcome to come by this afternoon and look. An offer like that is why you should put your general location in your profile. I am in southern California. I am running a 181 block with a 153 head because I didn't have time to build a manifold for the 181 head. Note that this will increase the compression ratio slightly. Mine is in a ’32 so I just adapted the engine to an early Ford transmission using the same adapter that is used for a small block Chevy. I retained the original rear end. I didn’t want to weld on the frame, so I bolted an angle iron onto the frame and welded on that. I used the bolt holes for the shock absorbers and only needed to drill one additional hole in each frame rail. I retained the original 153 cubic inch rubber engine mount to reduce vibration being transferred to the frame and reduce stress on the bracket that held it. I have attached a picture of my engine mount along with a couple of other pictures (note cleaning up the engine compartment is on my list of things to do). I used a generator and mount from an early Chevy II 6 cylinder because I liked the way it looked compared to an alternator. I am using the finned valve cover and side plate from a Mercruiser.

 

Thanks. I’m in NY. I’ll update my profile.

is that a stock rubber part that your tabs attach to?

 

Thanks for updating your profile, I guess you won't be dropping by. The rubber part is a stock mount for a 1962 (and up?) 4 cylinder. They may be discontinued. The 6 cylinder may be the same? I actually had a 4 cylinder Chevy II stick vehicle when they were new and loved it. They were quite rare.

The rubber mount according the Nova parts sites suggest the 6cyl part fits 4cyl. But I’m also lacking the mount brackets that mount on the engine, being all mine are boat motors.

that got me thinking that there is no reason I can’t build a couple since it’s an L bracket with some holes essentially

 

If you want a 1/2 Z-28 you build a V8 and use 4 cylinders. It’s been done in Land Speed racing for years and will out power real 4 Cylinder 3 to 1.

 

The advantage would probably be the cross flow head.

 

If anyone wants a project, I have a 153 with the start of adapting a SBC head.
Block will need some welding with silicon bronze.
I have block, crank, bearings, head, pistons, rods, cam, bearings etc.
Message me if seriously interested.

It might be easier to buy a mount from a 6 cylinder if they fit. Remember the drivers side bracket also mounts the generator. Sorry I couldn't get a good photo.
