What were the stock dyno numbers?

good numbers and I'm expecting big cam shaft specs - but it starts to fall off at 6200?? Again, I'm making the assumption is a decent sized cam that would pull hard up top.

Even still, I bet this car is insanely fast on the street and I bet it outperforms many other peakier setups at the strip too. The stock gears in this car are not well-matched to the power-band once you put a high rpm cam in it.
I'd guess duration is no more than 250 in either case but probably 230's/240's and an LSA between 109-112. Again, my guess.
AHP is not about huge cams on the street if you haven't noticed. They make smaller cams with lower LSA work well wit their heads.

^^^^^Me too. I'm !MSD but pretty well have everything else. If I had the intake I should be close to the #'s this combo posted above on a DJ.

We use the DynoJet correction factor on the DynaPack dyno. The numbers posted (DJ corrected factor numbers) will be very very close to what an actual DJ would read

Id guess this is an e85 car with around 13:1-13.5:1+ comp and a 240°ish cam. Too much torque for much else. That initial low speed torque spike I wouldn't pay much attention to either and call it 450 down low.
Nice numbers but I'd like to see some more details

We use the lowest correction factors available on the DynaPack.
We recently had a car that put down 605rwhp on the DynaPack go immediately after to a local DynoJet. Same car 4 hours later put down 592rwhp on the DynoJet. The DynaPack and DJ number not as far off as some like to think (when using the correct correction factors on the DynaPack).
