1/4 mile top out question for mods....

i was wondering, i am installin dart 200cc heads w/ 1.6rr and stealth ram, 3.73 10 bolt rearend, shift kit, 2800-3200 stall, stock internals, 150 wet shot of Nitrous, and custom burnt chip(pcmforless.com)....i was wondering if i would have the problem of maxing 3rd gear out without my cam installed?the cam i am buying later will be the zzx cam, but money is short and wanted to see if i could get away without it for a few months??? i got a lot of street racing events at local tracks, and was hoping that the gears would not hurt me at the end of the track...thanx for any/all of your help

I'd say with the 373 you will run out of gear. My car has 373 and I run out about 3/4 track and I'm at 5200rpm. The cars running 13.1 at 104mph.

you can always step up to 28" tall slicks, they are good for another 8-9 mph in the quarter easily.
