Yes. However, I don't think that taht is really the question your wondering about. Will it stay bolted up to a 427? The last I heard, the 700's were only good to about 400 horse, when built properly. That motor is going to have a lot of torque, and maybe a lot of horsepower, depending on how you build it. Now, they may be building them to handle up to 1000 ponies, for all I know. I didn't really get into them because of their weekness. That overdrive would sure be nice with a set of 5:38 gears though. You wont have a problem bolting it up. Where you will have to do some research is the flex plate/torque converter. You may have to redrill the converter holes. That's no big deal though. We have been doing that forever. Just remember the loc-tite for those converter bolts. Those things are messy when they come off on the big end.
No. blocks are not the same.
First of all, A powerglide and a TH 400 turbo are 2 different transmissions. And YES either 1 will bolt right to the big block engines.
It will if it is a turbo 350 with a Chevrolet mounting pattern.
It should, but all you'll do is wreck that transmission.... the TH350 isn't rated to handle that kind of torque. You'd need a TH450.
Chevy used to make a 427 big block, but the 427 small blocks are made from aftermarket parts.
427 = 4.250" x 3.76"
A 427 bored .60 over is 438.8572417 or basically a 439.
Chevy's 427
1966
yes
NO! The 427 Chevy engine was not sold by GM until 1963. The 427 is a big block engine and the very first big block was the 348 introduced in 1958. The 409 was introduced in 1961. The 427 in limited production only in 1963. The 427 was later released again in 1966 as a production engine. The largest engine every offered in the 1957 Chevy was the 283 V8. You could order this engine with mechanical fuel injection in 1957.
