hello, i curious about what my lift will be when i go through my 302 in my 87 150 w/a 5.0. ive got a summit brand cam 204/240 duration........448/472 lift.

im gunna get a set of edelbrock performer rpm alum heads, and now im thinking about what type rockers to get.

can anyone tell me what the lift will be if i get a set of 1.7 roller rockers?

the springs on the heads im getting can handle up to .575 lift

thanks

 

its easy to figure out, divide your max lift that is listed by 1.6, multiply that number by 1.7 and that will give you the new figures

 

476/502 thanks!

 

take the lobe lift on your cam card and multiply by the rocker ratio.
