Effect of 1.55 rocker levers vs 1.60 in my combo???

[87LtdT]

I very recently learned that the roller rocker levers that I purchased for my .25" stroked, .020" over bored, 218/212 roller cam, TE45 turbo'd engine are not the 1.60:1 ratio that I wanted...instead they are stock 1.55:1

I bought them from a forum member who also thought they were 1.60's.

Asking learned opinions of the power differences between 1.55 and 1.60....

Said another way, is it worth the money to get a set of 1.60:1 rocker levers??

Thanks, Bob

There may be no gain going to a higher ratio. The total valve lift in my application is .496 with the 1.65's and its a small comp 212/212. Car still made over670hp on the 133.4mph pass. It made even more at 33psi. Most of the sigs i read on this forum with better parts than i have cant even get it to go 130mph in the quarter. 10.50's should be easily attainable with your parts
