i decided to go with this cam, should i stay with 1.6 ratio or step it up to 1.7 the rest of my motors stock except exhaust

HACKGT350

need specs on the cam i cant read your mind. anyway take the lift of the cam and multiply it by 1.6 and it will give you your total valve lift with that rocker arm same goes from the 1.7
