I do not need the one I have rebuilt as it works fine. have another OHC that I am looking at converting to a Sprint 4bbl. The Chevy HB is remarkably close to the 1bbl HB for the Pontiac 1bbl motor. I have a OHC 1bbl HB and it is 6.75" wide double groove. They sell for $55.

The Sprint HB is 8 and 11/16" wide and double groove and very hard to find. So was it 10 HB's that it took to get them to make them? I might be able to send them mine to get them to reproduce them?
