Standard roller rocker on ford crate engine?

[kevsstang]

what is the standard roller rocker on ford crate engines? Also can a 1.7 rocker fit with the same valve covers? Is there any HP gain by going to a 1.7? thanks for any info

i believe it comes with the 1.6 rockers and yes you can use the 1.7's which would increase lift and hp. you can also go with the 1.72 rockers for a little extra. all will clear but you might need to pull the baffles in the valve covers. it doesnt harm anything and some can clear without pulling the baffles.

either way it is a good upgrade.

how much HP can i expect to gain from the change?

10hp is usually pretty common.
