Hey to all ,
I just resently had my 2.5l head rebuilt and also had my camshaft grinded . (stock)
I assembled the engine , everything was cool . but noticed that it didnt have the balls that it hould've had . My 87 325is bucket is faster .
#1 cylinder before the rebuild had 155 psi .
#1 cylinder after the rebuild has 120 psi
A friend who is a machinist at Larrys Performance Shop in Montebello , Ca told me that Regrind cams will have lower compression than a Factory Cam .
Is this True ???
