Re: 71 C-10 Big Block Swap

Good looking 454s.

We just put a '74 454 from a C-30 into my '71 lwb stepper. We had to use the BB mounts out of a '75 to get the header clearance for the style hooker headers I have.

This is not a power machine though, it is hooked to old style 4 speed transmission with an open 3.73 rear.

We could not use any of the pre-drilled holes and be able to mate up to the transmission.

I did not realize I would have a heat soak problem with my starter running headers so now I have to get a mini starter. I should have though since I know others have had the same problem.

We used the BB radiator shroud out of the '74, but had to modify it some to clear the crank pulley, power steering pump and alternator.

I still have not got around to taking pictures, I guess I better add it to my to do list.
