If you guys had your choice which would you build? The 350 or the 400?
I've heard good and bad about the 400. It overheats if you don't build
it right, but it has more torque. 400 cost a little more to build. I got
a 350 out of a 78 chevy that had a blown head gasket. Got a 400 out of a
76 GMC that I used for plowing snow until 2 years ago. It's going in a
personally i'd stay with the 350.
a "lot" cheaper to rebuild
parts avail. all over the world
you shouldn't need that much torque in a '53 chevy
i had similar decision to make for a '54 ford. it was a 305 vs. 350 . went
with the 350, saved a fortune and hardly anyone could touch me. good luck
The Chevy 400 was what the call a siamese motor. The cylinders had no
sufficient water jackets. The cylinders are very close together. You can
use the crank out of the 400 and put it in your 350 and a big bore kit
to bring it to 383 cu. in. This will give you a lot more power than the
400 could ever do. They are also very dependable. There's plenty of
performance places that can help you as well as some hot rod magazines.
The 383 is a very popular motor. Good luck.
This requires machining the 350 block for the 400 mains. Most machine
shops are familiar with this procedure, since its so common. You
should also use the shorter 350 rods which requires special pistons.
The 383 is a good motor and kits for building them abound. If I had
both motors on hand it is probably what I would build.
You could put the 350 crank in the 400 block and make a 377. Not as
popular, but the parts are available.
