I installed a FAST 90 Intake and Holley 90 TB on my small cam 346 with stock LS6 heads in a desperate attempt to get my ET below twelve seconds. I have not yet been to the track but I am very optimistic. Power is above 350 at 5000 rpm and stays above 360 beyond 6500.

Excellant. I think you have a very good chance of getting that 11.99 et. Nice broad power curve. I bet you have one heck of a daily driver. Also your power curve is relatively flat from 5500 to 6500 rpm.

You should definately port the intake and tb if you haven't already. Mill those LS6 heads after porting them a bit. That will guarantee 11's with good tires on the back.

Nice flat torque curve bro. Good do it yourself numbers. How much timing advance are you running ??

22 degrees from 4000 rpm on up. Experimented with 24 degrees max but the gain was so small I went back to 22 max.

My car made the most power with 28*. Sounds like your car didn't like 24*.

i just re read your sig. That is a very small cam. You ran a 12.01 with a 1.57 60' time. I don't think you need to work on your driving at all. Driver mod successfully installed. A little more hp and you are there. GOOD LUCK bro.

I can't see how you could miss 11's

Great numbers with samll cam and that Rearend and drivshaft.

Congrats on solid 11sec car.

You shouldn't have ANY problem getting into the 11's with that much power and a 12 bolt out back.

I think I would take that setup any day over many of the 420-430 RWHP cam-only graphs posted around here. Way to go with that "old school" cam, too.

Thanks, I am pleased with my results. I was never tempted by a large cam but I do sometimes wish I had gone with the good ole TR224.
