Like it says? Anyone installed the 1.7 stock ratio and have numbers? How about the 1.8s.

Nasty N8, a board sponsor, was selling them at an intro price. He's still in a position to get you a set. They look so good I don't want to put them in and hide them. I was also able to get a great set of Manley push rods to match.

Does anyone have a dyno of just a HS upgrade? Ive heard people claim that roller rockers can gain you as much as 10 RWHP...that seems awfully high considering we already have roller fulcrum rockers. Is there really that much of an improvement?

There is no grinding needed the98 valve covers need a little on the edje of the bolt holes. We did a back to back with stock and then with the 1.7. First pull gained 8rwhp second and third gained 10rwhp. Still have them at the intro price of $320.00
Thanks Nate
