1.6 to 1.7 Rocker ratio lift conversion???

[95CobraMike]

If you have a cam with .498 intake and .512 exhaust with 1.6 rocker arms....
what does the lift become if you change to 1.7s?

i dont know if there is a conversion/equation... maybe there is?

 

[legalize420]

498/1.6 * x/1.7 = 529

512/1.6 * x/1.7 = 544

I'm not positive but I think it would be .529 and .544 ?

Thanks guys...i should have thought of that.....

if the .544 is on the smaller 1.600 exhaust valve of Twisted wedge heads (.540 max lift) should i have problems or should i just stick with 1.6 rr's just to be safe?? or should i go with track heats which are good up to .600??

get new springs if your going to run the 1.7 then.
