232ft lbs
50 shot
200 hp
306tq
75 shot
230hp
325tq
100 shot
302hp
394tq
I will post the graph when they get it up.
305 TBI small cam (stock LT1 size) 6speed moser 12 bolt 4.10's On Nittor DR. on a Dyno Jet!
I was looking for 250hp and 350 tq on the 100 shot biggrin.gif I let the car cool good and got the bottle temp to 1,100 on the 100 shot. I pulls real good now. (I just need to learn to shift it faster now)

Yes. The stock snorkel intake is very small, especially with the cold start diverter (or whatever its called) sitting in the way. Even with an open element air cleaner, your fuel injectors still sit in the way of air flow. Thats why there is a 60 hp difference between the 305 TBI and the 305 TPI units stock (170hp TBI -> 230hp TPI).

Track times
Started out on Nittos and a 100 shot. I think my best with that setup was a 8.63 The tires were spinning pretty bad. So I got tired of that and put my et streets on and went a 8.32 (100 shot)
Then I put in the 150 jets and went a 8.05 1.70 60ft @ 85mph. then a 8.07,8.08,8.08.
I really wanted it to go in the 7's maybe with a little more traction and some tuning it will be there. The car ran great and I had a blast shifting the gears. I will try to get some video's up for you guys to see.
I also wanted to run a 200 shot but I didn't have any jets for a 200 shot.
Might just have to stick with the 150.
