Inliners International Forums General Discussion Engines 235/230 engine swap

i have a 59 chevy pickup with a 235 in need of an overhaul& have found a rebuilt 230 from a 65 chevy truck for next to nothing.would this engine bolt right up & if not what changes would have to be made.power wise how do the 2 compare.i have visited this site over the last few month since i bought this truck & you guys have inspired me to not do as was planned which was to swap out the old 235 for a 350.thanks in advance for the help i know will be coming.

The 230 is an entirely different animal from the 235. To use a 230 in your '59, it will require replacing everything thats in front of the tranny and making motor mounts. It's possible that someone makes mounts for this swap, but I don't know who. Possibly check with Tom Langdon or Buffalo or Chassis Engineering...

The 230 is definitely a better engine, but if you can, a 292 would be even better.

thanks for your help gearhead. i will just have the 235 rebuilt & some day upgrade the intake & exhaust manifolds.we did find a home for the rebuilt 230

was checking another post on gmc 270 & 302 would one of these engines bolt up in place of my 235 in a 59 chev pickup.

Here again, this is "a different animal" and requires major modifications to fit in there.

A 261" engine will 'bolt in' and can be built to 278 or 292 CID. All your 235 stuff will fit it too.

That 'post' was an engine question for a GMC truck, which the 270/302 engines are.

Good luck.

A GMC engine isn't that hard to drop into a Chebby - it's a fairly common swap. It' isn't a direct drop-in like a 261, though.

thanks for the info on differant engines.i have a lot to learn about 6 bangers after having a sb chevy under the hood of what ever i was driving for the last 35 years. rodtest
