Big block swap 73 k10

[Mike_The_Grad]

Hey everyone, I'm going to be swapping a 427 big block(454 block with 396 crank) into my buddy's 73 k10. His 350 sbc gave up the ghost. He picked up the 427 on impulse. So it's happening one way or another. I explained to him the kinds of changes he needs to make for this to happen. Obviously exhaust, motor mounts, and compatability with his drivetrain. The 427 is a long block. It has pro comp air gap manifold, oval port heads, and tall valve covers. That's pretty much the extent that I know so far. P.o. said it made about 425 horsepower and it was originally going to be put into a old hot rod style coupe with side lift engine covers.

So, I know I need to find out what cam it has in it to make sure it's not some crazy high rpm style race cam and that it makes enough vacuum for power brakes. But I also need to find a powersteering bracket/pully setup and an alternator bracket that will clear everything and align properly.

Any tips on motor mounts/frame brackets or engine crossmember modifications? Any thoughts on a accessory drive setup that's not chrome or billet aluminum shiny stuff? Hopefully more along the lines of factory. He does use his truck off road and it's lifted pretty high. Not sure how much of a lift or how tall his tires are or his differential gear ratios. But I can find that stuff out relatively easy.

Any input is appreciated. Thanks.
