The Stovebolt Site Forums The Shop Area Engine Shop Will a 235 bolt right in?

I would like to replace my 216 because it's froze and I don't think I can justify rebuilding it. Will a "newer" inline bolt in? Thanks

There is a lot of material here on this subject. I would suggest looking in the tech tips first and then doing aforum search. The short answer is yes.

Thanks trucker, Maybe I'm not using the search right. I'll also try Tech.

Wahoo40, The easy motor to replace the 216, would be a 1954 235 or 261 Chevy as these were the last motor with the 216 style water pump, easy deal. Those however are not easy to fine so next good motor is the 55 to 62 235, which will require mods to the water pump. Like truckernix said, read the tech tips.
Also you may want to get a catalog from Patricks antique cars in Casa Grande, AZ ,has a section on all the mods you'll need plus other neat stuff. his phone- 520 836-1117 or web site www.patricksantiquecars.com

Best of luck

If I'm thinking right,...the rear motor mounts and bellhousing mounts are the same? I want to run an automatic trans. Would this mean changing out the rear motor mounts?
Thanks for the info on Patricks.

First it was just the engine, now it's the transmission which is going to mean a new rear end. See how addictive this stuff is?

Putting an automatic behind a 235 you have two options, first being one of the two old automatics that were offered behind it, the cast iron powerglide, or the 4-speed hydramatic. Neither compare to modern automatics very well.

The other option is an adapter that allows using a V-8 bolt pattern automatic. Going that route you've complicated the rear motor mount and will have to convert to open drive, probably meaning changing the rear axle.

The 235 and the related motors, the 261, and GMC 228, 248, 270 and 302 all have the bolt pattern and can use the adapters, but if you need an adapter you need the right one, Chevy or GMC because of crankshaft difference. And swapping to a GMC complicates the front motor mount.

Later GM inlines, the 230, 250, 292, don't need an adapter to run the modern automatics, but require new front mounts in addition to rear, and mean you are changing other things too.

And of course modern automatics fall into multiple catagories too, and which you choose may bring more complications.

Give us a better idea what you are trying to accomplish and we might be a bit more helpful...

I guess if it was easy everyone would be doing it. LOL...
My plan as of now,(things have been known to change) is to run a later inline 6 with a turbo 350. Apparantly an adapter also. I will use an s10 rear with Chassis Engineering rear spring kit.
I'm in the process of installing a MII front suspension from JW Rod Shop which mounts low enough to allow an inline to fit.
I would like to use the stock motor mounts if possible, but I guess after going this far that wouldn't be too big a deal.
Where would I find this adapter?
Is there a certain cut-off year where the inline engine won't be a good swap into my 1940 chassis?
Sorry for all the ???s, I like to learn a little beforehand, I hate buying stuff that won't work!

If you are going that rout why not use the 250-292 engine. It may already have the 350 trans or one will bolt right up to it. It has side engine mounts that will work with your Must. II front end.

What years were the 250-292 engines made, and what donor vechicle would have had them? With this particular MII crossmember, the original front engine mount remains intact. With others I've seen, the first thing the instructions tell you is to cut the front crossmember up to the radiator support.
