Would L98 alum heads be good upgrades for an 82 Xfire?

LMAO...So, using NOS is NOT naturally aspirated, that IS BOOSTED or a Power adder just like adding a turbo or SC. If your running just two TBs, turn the NOS off and see what it does. I would be very curious at the specs and I see you are running a 4.09/4.10 gear. Ha, I'm just running a punny 3.31.

Melting Slicks
Nope, mid 12s right now. I know Ben is running 12.20s with a 383 so I guess we are doing something REALLY wrong if you are running 11s with a 355 motor NA. If I were to go to a bottle which I will never do, I could run 10s, but what's the point? Mine are 2.13 TBs and Ben's are 2.20, so again, we must be doing something wrong with a 383 motor. What ECM are you using and trans? I don't run slicks, just DR MT ET Street Rs. which hook pretty good. There was a guy with a bone stock 84 with a 125 shot and ran 11.70s. I just find it hard to believe you are running 11s on a 355 all motor, but whatever. Where in TX are you? Oh and mine is 100% street-able.
