ET does not equal horsepower, trap speed does, and your trap is WAY below what it should be, therefore is not making nearly the horsepower it should. I would say you are down a good 40rwhp from what the car should be making. A bolton LT1 traps 104-106, your car should be trapping around 111-112. GET A TUNE.

My bolt on car was trapping 105.5, shifting at close to 6k. What are your shift points?

i feel like those shift points should be slightly higher with the cam, even though its jsut a hotcam, also ls1 pull reall good in the higher speeds so i wouldn't sweat that to much. Get the car tuned, maybe get rid of those winter tires and just enjoy the car.

I' heard the shift points should be 6-6200. Shift higher after the tune, i bet u catch him! Look into pcmforless for the tuning, on a stock car they picked me up 18 horse. Now i have to have a reflash for the 503 cam and heads and its only 50 bucks for the reflash. They have really done right by me. Check it out. Just my .02

I have a procharger for stock LT1 that will make it scream.......I did 383 so I'm selling it. And then get it tuned

Back in 97 procharger had a 600b...worked great for Stock motors....and hot cam.
