It’s about that time

Soooo, I got a 671 core at carlisle, along with a 2x4 offy intake for my 400, or for that matter any B block that I may come across. I’ve done quite a bit of research on rebuilding the sucker and it doesn’t seem to be outside the realm of possibility. A good friend at the machine shop that will stay after for a 30 rack helps a ton. Anyway, at this point a B block blower manifold is pretty expensive. Especially since most of them need to be made anyway. Anybody have experience fabbing the mani? Purchasing a dust collector not out of the question either. I don’t know if anyone here has converted the diesel blower to gas or not. It seems pretty straightforward with what i have gathered. I have about 8.2:1 comp and a 110 centerline on my cam. I feel even at low boost, and two 750’s I can really get her moving. I figure my mild build will hold up. Might change out rods,and at least bolts. Yes I realize I may only save 1000$ on doing it myself. I would rather collect the parts and play. And with no real time frame, I can gather ideas
