Is their any good gains in horsepower going from 1.6 to 1.7 ratio roller rockers?

Like going from 560/576 lift with 1.6's to 595/615 with 1.7's

Ya alittle bit more horsepower but not worth the money...........

Uh'... You will get more lift and a little more duration. You should get some HP. You may want to up grade your intake, exhaust, & fuel to take full advantage of the new rockers. Getting aluminum rockers, and lighter rods should help also.

How much of a horsepower gain switching to 1.7's

10-15 hp ???????????????????????????

If you have a basic stock engine and your going to put the 1.7 rockers your lucky if you get another 5 hp just aint worth the money or the time to do it and if you must pay somebody to do it Yikes! alot of $$ for a small gain.Now if your were rebuilding knew I would say through them in.......Good luck

Is it worth it to switch to 1.7's on a moded motor like mine

Madey this will help:

306
11.5.1 Compression
AFR 205cc Heads
Lunati Cam (242/252 Duration @0.050) (560/576 Lift with 1.6's)
Edelbrock Victor 5.0 Intake
75mm TB

My lift would be 595/615 with 1.7's
Are you telling me I won't even gain 10hp switching to them ???????????????????/
