I have a 66 chev C20 bought brand new in Nov. 65. It has the original 283 V8 and it has just a little of 100k on it. Would like to replace it with a 454, for more power pulling a trailer, but not sure if it will bolt up to my 283 bell housing, and if motor mounts are close, probably not. Maybe if the bell housing from the 454 would bolt up to my original 4sp. trans. Called wrecking yard and got different answers. Anyone know who would know if this swap would work? Thanks, Phil

All Chevy V8 bell housings have the same bolt pattern from 1955-1999, not sure about the newer LS engines.

Not sure about the motor mounts but the frame mounts are the same.

So what you are saying is the bell housing from my 283 engine would bolt right up to the 454 engine. If that is the case then my 4spd. and everything would be a direct swap. I wonder if the extra length and height would have enough clearance for the frame cross member as well. There is quite a bit of room under the harmonic balancer and the front frame cross member now. Thanks!
