Sorry don't know all the specs. Vette Doctors built it.
It is an ls2 block with 4" crank to bring it to 402. Not sure the cam specs.
American racing headers, flowmaster exhaust,l76 intake with 90 mm tb (I think) and vararam.
Rebuilt 4l60e trans, 4000 stall converter, 4.10 gears. That pass was on 26" ET Streets and MT fronts.
I switched to a different combo after that so did not finish dialing it in but it will be back in the car next year.

Verdad Gallardo Mine are the TSP cnc version. Just keep in mind that I only have 375 ci, and my 4L80E eats 25 - 30 more RWHP than a 4L60E & 30 - 40 more than a M6 plus the 9" and 28" tall tires eats even more. Thats why I gave you the weight of my car and the other goods.
Does anyone have numbers with ported L92's?
I saw the SDPP site and they were claiming 358 max cfm.
I'd like to see what people are actually making power wise off those heads, they seem to be a very good flowing head for the price.

i have a 402 with Livernois Stage 3 L92s, and went 11.20@126 in a 6 speed car with a stock gear, stock 10 bolt, bone stock suspension, fully loaded, and stock wheels with bald *** nittos.
Ported L92's I'm still waiting to run mine. The last 2 runs the clutch stuck to the floor.
My ported L92's flow 346 intake & 225 exhaust @ .600.
I made 485/441.

Cartek just built a 441 for me with L92 heads and intake and the car made 530 rwhp and 630 peak torque. These #'s are on an f body with a non lock up 8" converter, th350 and a Moser 12 bolt. Compression is 13:1 and it's a hydrolic set up.
i think no one has seen "stellar" numbers with these heads because of the intake choices. i see very few using a carbed style intake. i really hope a super vic comes out for these heads, but for now i think gmpp's intake is the best choice for the racers. i'm using a carbed intake, and thank god it's not going in a 4th gen fbody.
