Okay I was wondering how fast of times you guys have seen on stock ported heads. MY lt1 is a 383 with carb. Yes I converted it over to carb and installed in a 91 camaro with 6 speed and moser 9 inch. I have ran 11.31 at 120 mph with no nitrous or supercharger. I have only been once and as soon as the car is painted i am going back to see if I can tune on it a maybe see 10.99 or 11.10. Just wondering if you all have seen any lt1 with stock heads in the 10's. Future plans are for 200hp fogger kit and hoping to see 9.90.

 

I plan on it sooner or later....

 

I hit new bests this weekend with a 11.26 @ 122 MPH. The motor is a 383 with ported stock heads and a PCM I am tuning myself with LT1 edit. I am creeping up on 10's and I think once I get the 60' and tune worked out I will get there.

 

95 z28 th350 trand, 370 ci lt1 with ported gm lt1 heads, I have gone a best of 10.01 @ 134.6.
