Hi gUys
well its time too put the engine back together after a hone, a new cam and some new lifters.

The old comp ratio was 12.5 :1 and i ran it on gas, then i went too Alky.

Was thinking of upping the comp ratio too 13.5 :1 to make use of the alky and the bigger cam.

This is the cam so i think the extra compression would help, what do you reccomend.

Dur @ .050" int: 274exh: 290 Lobe lift int: .4381exh: .420 LSA: 114
