Indy Edelbrock heads

fstfsh66,

From what I have heard, the BB rockers used on the Indybrocks, are from Crane. They have no markings on them but that is what I have heard and what they look like. I am looking at them as I type. As for blower manifolds for aftermarket heads, I approached BDS many years ago about a manifold for my W2s and they said they would make one if I paid for the R&D. Actually, back then, it probably would have cost me about $3200. That was (and still is) a little out of my league.
