494 pontiac
So in talking to comp cams my springs at 525 open were not
strong enough for my Solid Roller cam.. they want 625-650
Problem is Comp does not make a spring for my head.. wonder why
Pontiac engine with a copy of a Cleveland canted valve head with
chevy BB valve train... should be easy.. not really
Pac Springs has a set but they are smaller diameter so I need
to change out lower retainer... his size is a couple thousands less
on the retainer so might have to have it machined
Never easy on this car
