ok i was checkin out www.paceparts.com


and i was lookin at the LT4 cam
this is what it says

well im gonna b runnin 1.5 rockers

my friend said that i should just take the valve lift and divide by 1.6....then multiply by 1.5 and that would get me the valve lift of it with the 1.5 rockers.....is this the correct way to do it?
if so.....then that means im gonna get bout 446/450 lift.....right?

Your friend is correct.

Thats right. Dividing the valve lift by the rocker arm ratio gives you the cam lift, which really is a more important number to have IMO, especially since quite a few of the cam specs I have seen dont specify the ratio used, and then you find out they used an uncommon ratio. Then with cam lift you just multiply that by the rocker arm ratio and that gives you the valve lift.

With 1.5 rockers that will be an excellent street cam for a 305. I think you are going to like it a lot

well i dont plan on putting this into my 305
im gonna build up a vortec 350.......lol

but thanks for the info
