Manifolds are not needed IMHO, you can make some good money casting a strong SB block that can handle 1,000hp, I don't think the R3 blocks are made any longer.
Well what are we going to bolt the new small block victor heads on? Edelbrock told me at Pomona races that those new heads will flow 350cfm and if ported 400cfm. But couldn't get a set. So I bought a new set of Indy T/A. :burnout:
