Yes a th 400 can be bolted to a 350 also a th350 and a power glide
same bolt pattern if the 4l60e was behind a v8 or 4.3and the th400 was from a chevy and not a (bpo or caddy )
YES, They are the SAME engines. That will be a direct swop/Bolt in.
as long as it is a chevy bolt pattern th400
you can do it and use only 4 of the bolts but they are not the same and you will not have much for strength doing it that way.
Yes...they are the same bolt pattern.
Yes.
The Buick 350 V8 engine and the Chevrolet L6 and V8 engines share the same bolt pattern. Pontiac and Oldsmobile 350 V8 engines share their own bolt pattern. There were also TH 350 transmissions that had dual bolt patterns and fit all 350 GM engines.
No the bolt pattern for the v6 and the v8 are different
If memory serves me right, back in the early 70's the Chevy V8 and the Buick V8 shared the same bell housing bolt pattern. The Oldsmobile V8 and Pontiac V8 shared a different bolt pattern. But, back then GM did have a turbo 350 transmission that had two bolt patterns that would bolt to all of their V8's and some of the vehicles were produced with that transmission. Whether or not you have that double pattern transmission you probably won't know until you take it apart.
No.
there is no reason you cannot put a car 350 in your truck, in fact any small block V8 will bolt right in.
The rod torque on a Chevy 350 V8 depends on which size rod bolt you have. On the 3/8 rod bolt the torque is 45 ft/lbs On the 11/32 rod bolt the torque is 35 ft/lbs
