3.73 for sure Ihad 4.10s and switched back to 3.73s the 4.10s cost me 3/10 at the track.
Long tube headers will make more hp.

RE: choices

Shorty headers are a complete waste of money. A lot of $$$ and install effort for only 3-5 HP tops.

Longtubes will give you 15-25 HP to the wheels, so the gains are actually significant.

yeah, if you cant grip. My friend had some mickey thompson et's on the back with 4.30's and I actually beat him a few times just because he couldnt grip. I had stock tires and gears.
