Hi,
JimN, thanks a lot!
Yes, the engine is non-Vortec.
Ok, I might ask for price of roller rocker arms for the base engine, if it is an option and maybe for newer TBI manifold. But MC did this type of engine only 1995 - 1997, after that MPI?
So EFI computer just "puts gas in", when crackshaft position sensor says so? When and how fast the valve is opening, fully open, closing and closed, does not matter?
Craph for roller cam vent opening is more rectangular, as flat tapped cam craph is more parabolic, as in time vs. vent opening x-y scale.
BR,
Pasi
