yes
A turbo 350 has only 3 gears. The 700R4 has 3 gears plus over drive and lock-up converter. And it is the same as a 400 turbo with overdrive.
No. The 400 is externally balanced, the 350 is internally balanced.
Yes. They are identical because externally the 350 and 400 are also identical.
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
You are probably thinking of the turbo hydro, 350. It was Chevies base automatic, after the powerglide. It had 3 gears, and was fairly tough. The turbo 400, was the heavy duty version.
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
Yes the cam bearings are the same.
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
350 and up to
I believe it is about the same as a 305 / 350. 600 lbs. I recently swapped a 400 into a trans am with a 305 and the car weighed the same at the track.
