Rocker Arms on the Ls1 trans am
Hows it going everyone? I was just wondering if anybody knew what hp gains can I get out of switching my stock 1.7 rocker arms for 1.8 ratio? The only mods that I have on the car is a Volant cold air intake and a slp loudmouth II catback.
My second question is what would people recommend headers or the rocker arms?

Silver & Blue- 02 Camaro SS, 04 GTO
Not very much, I believe it is less than 10hp at the flywheel so that's about 7 at the wheels. A good set of rockers will cost you between 300 and 500 dollars so I would put my money into a good Dyno Tune. JMO
My ride is a 2002 Camaro SS SLP #3296 with 30k, LTH, 3" Y, CME, Frost tune, K&N, ported TB, Blackwing lid, Bellows, MSD, Denso Iridium, and 85mm MAF, Bilsteins, Eibach springs, SLP strut brace, Adj. Panhard, TA Girdle, UMI, Pro 5.0, Nitto NT555
My wife has a 2004 GTO with the rare SAP, 18" wheels, K&N Cold Air System, MSD, Ported TB, Frost tune, Denso Iridium, Flowmaster cat-back, 3200 Yank, 75k
