shouldn't have a problem with that.

I took a 350 out of a 78 chev p.u. and installed a 454. everything works easy. I used the 350 mounts and even nthe distributor off of the 350 on the 454.

I would look into some different springs.

my 75 truck 454 was rated @ 245 HP...its a low compression smog motorso it didnt originally have big HP....the big differance between it & your 350 will be torque.
