Thank you! Lol, I wish I could take credit for the build but I can't. My good friend built it. I do not know as far as the K frame what he did or used, the car was a 318 car. He used a B body ex manifold on the p/s and I think the d/s is a C body 440 if I recall? I could run the casting number to check tho. Sadly my buddy passed away several years ago unexpectedly and there is no real info or notes so to speak of what he did or how he built it. If there is anything you want pics of just let me know and I will try to get that for you!
