Would a 1.75 exhaust valve be needed on a 390?
By Bill Ballinger - 08/19/2000 9:16:09 AM; IP 208.44.154.54
I would think that a 1.65 would be plenty big for a 400 inch range engine, and the smaller 390 bore would actally shroud the 1.75 so bad you would lose flow by the interruption of the flow ring.
This thread, so far...
