Engine setup - 1.5 or 1.6 rockers..?
Hey
Please help me chose the rollers for my setup,
I have ZZ4 cam, very heavy ported stock heads with 2.06 and 1.6 valves, very heavy ported stock intake manifold and stock runners.. I do not fear about the heads, they will be shure good for the power that ZZ4 can give..
the heads have been mashined so that they can take for shure .560 lift i dont know if anything more, but they said that .600 will be good to...
Of course exhaust, long tube headers, intake etc, everythings just fine...
Should I stick with 1.5 rockers or change to 1.6 ? Wont this be to big for TPI..?
I will be changing manifold but it will be in a two years or so.. :P
Thx
