200-4R into 78
 

I'm sure someone on here has done this. Currently my car is a 403 Olds powered car but when/if CA changes smog laws I'd like to go Poncho power. I know the pattern on trans is the same BOP but more my question is what all is entitled in the swap? What car trans came out of, probs that came up and how they were delt with etc. Just got this car. 78 formula
