Hello, another question for you guys. What I am trying to figure out is, what the lift would be on a fms B, E, F, cams would be with the factory rockers. Also what size is the factory rockers? Also if it is possible could someone give me the correct inches of lift on each cam with 1.6, and 1.7 roller rockers would be. I would much appreciate it, trying to plan ahead on what cam/rr size to go with.

thanks 5.0_sleeper
 
Factory size is 1.6... I know the b cam is .480 with factory style rockers, and thats roughly .510 - .512 with 1.72's. thats what I ran in my last combo... Could not tell ya about the rest.
 
The stock rocker ratio is 1.6. Take the gross valve lift of the cam and divide it by 1.6. This will give you cam lift. Now multiply it by 1.7 and this will give you the new gross valve lift specs.
