Ouch. Justin is a good friend and we don't make grudge matches between ourselves. Rather we whoop on everyone else.


Quik- VERY few people have made a solid 500+rwhp on a properly calibrated dynojet. Justin got a very good deal on the shortblock, and spent $2,200 TOTAL for the full assembled 5 axis CNC ported heads with an L92 intake.

Our Stage 3R's, AFR's, and Trickflows cost way more then that with a FAST 90/90 setup. These L92 heads are still very new, and to be honest I didn't think Justin's car would make what it did. Going through 1 3/4 headers with an L76 intake, the numbers are pretty decent. The compression is only 11:0.1 at that.

both 408s had PTV issues and they both had different heads on them(but both heads/valves managed to come apart the same way)<--installer error cough cough so u can't blame the heads!!!, the marks on the pistons are there to prove it. even ur old 6.0 with the t-rex cam had valve marks in the pistons! i also heard u wanted to change the other 7 pistons on your 408 because they have makrs in them from the vlaves whacking em.... i don't see that many people having probloms with L92's at all!!! like everyone else says the're new just give them time.

Hang on 1 3/4 headers, no intake and 505 and 475 torque? Okay-how about you get some 2" headers, forget about the nitrous and slap on a F1A-I bet you make 850 rwhp at 12 psi!!!

Sweet combo bro!!!!!

motor is 11:1 compression and is built loose for the bottle.

headers and hopefully somebody makes a damn intake for these heads soon, plus going speed density and underdrive pulley should help pick it up some too

Glad to see the car working great Justin! Now thats a plan that came together, 500+ is a great start for a nitrous motor!. But don't forget about us little shortblock guys We gotta make sure that bottom can take what you guys throw at it!!! The 300 should just start to warm the plugs
Chad what size are those runners? And do you have dealer programs? PM when you have a chance...

That is some great rpm for that L92 topend!

ya, Dave, the shortblock is perfect, i was rocking the shirt your wife gave me when i was at the track, i told everybody who built the shortblock, so i would never forget about who built the heart of my setup. i am more than happy on the results i got for how the setup is now. i hopefully when i finish everything how i want, the car should make a pretty strong five-something at the wheels.

car last week in a DA of +3000 feet went 11.53@124mph with a 1.9 60ft

this is on a stock 10 bolt, stock gear, stock 16s all the way around with nittos on the back, stock suspension that came on the car back in 1999, and it was hot and humid as a ****. my goal after i do suspension, rear end, and do the rest of the motor how i want, is to hit a decent 10 second time all motor, then ill spray it, 300 shot is what ill go with, i dont think i want to push it any more than that. should fly pretty good for a 6 speed with leather interior thats fully loaded. its going to suck when i have to put a cage in it, but its cool im going to need it

now thats sweet! congratulations! you got easy 10's in some good weather, if you can plant all that power.

ya, planting power, and not breaking, usually dont go together, how the car sits i would like a lower 11, after i finish everything motor wise, its got high 10 capabilities, then suspension and rear end should put it at a strong high 10 second car all motor

88LS1BLAZER-right on bro. At speed inc my car made 424.1hp 404.0tq. I went to vector motorsport's dyno(kirk)a week later and only dynoed 368hp 350tq. I then over time got the same motor on the same dyno to produce 463hp 414tq. I will soon have my 402ci w/l92 heads and l76 intake dynoed there soon....I hope it puts out there and most of all at the track.
