Congrats on scoring the Cuda. There are many top notch experts on this forum that know far more about restoring these cars than I do. The only thought I have is on the drivetrain. Depending on storage space and budget, you might consider setting the original 318 drivetrain aside if you want 350 to 400 hp. I'm guessing this has a 904 automatic and an 8 1/4" rear end, which weren't designed for that much power. It will certainly be easier (and possibly cheaper?) to get your horsepower with more displacement, either with a 360 or a big block engine? Again, I will defer to the experts but just a thought. In any case, welcome.
