well im fixing to do gears and buy some new ET streets.
ive been getting lots of people telling me to go 4.10s and a 28x11.5 15 ETstreet, saying that combo would be good for now and future plans i have for the car.
but im just curious at what RPM people are trapping with this combo.
my mods are SS4000 stall,MS3 cam,full exhaust,tuned, car is gutted.

i'm running a similar setup, however I havent had it out yet.
28x10.50 ET Drag
depended on converter slip i believe i should be good to about 127 mph trap

I can testify for my friend who has a z28 with a small cam, headers, bullet exhaust, MAF, air lid, K&N, 4.10 gears, 28" tall hoosiers, BMR trac pac, Competition eng shocks and nitrous. He ran 8.13 in the 1/8 and 7.30 on nitrous. No 1/4 mile times yet. He doesnt even have a tune. I will tell you that after the 7.30 pass the rear end had enough. He broke teeth off of the pinion. I HATE a damn 10 bolt. One of my first mods was the 9"

How high are you going to rev it?
Assuming a 6700 redline, it should be good for 124-130 MPH depending on how efficient the converter is.
