Hello, I just put a 425 horse 383 in my "51 chev pu. I put a "80 camaro front stub in front of a boxed frame and that gave me all the clearances I needed. I used a 1983 S10 interior and column. The wiring was interesting but no big deal. The Chrysler posi does a nice job of keeping it straight. I'm still finishing the body work. I got the engine as a prototype and it runs out great.
