Ron, after talking with cam people and engine builders a roller cam is like having 1 bigger cam size then a non roller cam. so your cam is like a 221- 228 non roller, which is a perfect size for your nailhead.
Intake was a modified factory 4 barrel. Cut out the carb ports and left the center divider, port matched to the heads. They had a 2" spacer under a loaner 835 Barry Grant carb for dyno purposes.
That made my day,,, that engine had a ''Doc dual plane'' mod. intake manifold.....Now, I got a new phrase,,,,,''Never sell a Doc dual plane short"......Made my day,,,:Brow::Brow::Brow::Brow::laugh::laugh::laugh::laugh:Made my day,,,,Made my day.....
Hi Urslo, I dont know if I missed this but was wondering what spring pressures the ls1 springs are that you are using?
