im thinking of putting 1.6 rockers on my lt1 and a pulley. how much of a gain on the 1/4 mile and how much hp.

1.6 RR's should give you about 5-10 if your car is in good running order and you have a decent exhaust on it to take advantage of the extra lift. pulleys are wierd though....some people dont see gains on the dyno with pulleys but will see a 1-2 tenth drop in quartermile. with those two combined I would guess around 3 tenths maybe 4 if you are lucky. hope this helps

I gained about 1.5mph in the 1/4 with the addition of 1.6 rockers on my stock LT1 (already had headers/Borla, etc.. tho).

I tryed the 1.6 rockers before I actually installed my cam. The rockers were good for a tenth and 1 mph.
