Question

That's it ?!? No one else wants to brag about their numbers? Shawn, your numbers are pretty comparable to mine although you do have considerably less low RPM and max torque however ....considerably more RPM to use. OnFlynZ .....you must have a beast there, surely that's not a 350.

What cams/heads are you all using?

Someone else post they're numbers (or times) please and tell me what cam/heads you are using. Feel free to elaborate on MPG and off idle response, low RPM torque feel. I'm just second guessing whether or not I should have gone the heads/cam route instead and want some feedback as to max power and low RPM torque and/or feel/response.

Advanced Induction ported lt1 heads, AI's 211 cam.. i guess that would be a short name for it?

stock ported LT1 heads for me...

best track ET has been an 11.91@117mph (negative DA that day) . I was on a 10 bolt @ that time. Best since then has been a 11.98@115 w/ my 12 bolt ~ in the summer.. another interesting note is I lost 30rwhp on the dyno after installing my 12 bolt, but the ET's don't really reflect it. partially due to the fact i now have a 3" steel DS vs. the 1LE.

Yes those numbers are off a stock short block with a .032 piston to deck. My heads are a combination of two porters. NightTrain66 and Dave of Flowtechinics. I was very sceptical of the flow numbers when I first saw them but the Raw HP of the end product backs them up.

It is a Beast that much is for sure. We were doing some fine tuning the other day and I nailed it at 55mph and it kicked sideways and carried the spin. I am putting a new set of Nitto 555RIIs on this week in hopes it will help traction some.

other then that it really is driveable. Can get hairy in the rain with the tight posi and 422 Lbs TQ down low but other then that very nice

BTW I only showed a 10hp loss with my Moser 12 bolt.

Are all these numbers you are giving, oneflynz, on juice or N/A, I noticed you have a dry kit on your website but you dont mention it at all when talking about your dyno numbers?
