Absolutely. You will need special bearings for it, but it will bolt right in.
No. The 400 is externally balanced, the 350 is internally balanced.
Yes. They are identical because externally the 350 and 400 are also identical.
yes
350 block, 400 crank. Main journals must be turned to accept 350 bearings. Stock bore is 377. .030 over is 383.
No. Standard 350 engines have 4.00" pistons, standard 400 pistons are 4.125".
yea its the same thing as putting a 350 head on a four hundered . the 400 heads just have seam holes that arent in a 350 scb
Take the crank to a machine shop and have the main journals turned to accept 350 bearings. Might be a good idea to have it balanced while it's there.
yes
Yes of course. All Chevy engines are interchangible with transmissions. For example, you can have a 305, 307, 327, 350, 400 with a turbo 350, turbo 400, or 700r4 big block are also the same
You need a crank from a 400 turned down to fit 350 main bearings and a set of 400 rods on the 350 pistons. Also need a flywheel and balancer from a 400. If the engine is standard bore, it would be a 377. A 383 is bored .030" oversize.
The bore and stroke is different, But if you set the 2 side by side they will look the same other then some 400 engines have an extra freeze out plug in the side of the block that the 350 don't have. 350 bore and stroke is 4.000 bore,stroke is 3.480 400 bore is 4.125 and stroke is 3.750
