6.0 ltr iron block bored .030 over
Calles 4" forged crank
Crower 6.125" forged rods
Diamond 4.030" forged pistons
CNC custom LQ9 high compression heads 2.055 intake/1.70 exhaust valves
Cometic head gaskets
LSX 90MM intake manifold and T/B
Mezeire Electric water pump
ARP fastners top to bottom, front to back.
The motor actually made more torque than the 666 I showed. We used an MPH graph instead of a RPM graph to smooth it out. When we pulled it we went from 75mph to 125mph in 1.25 seconds. This was thru the TH-400, Moser 12 bolt with 3:73s and on slicks.

Never ran mine on in the 1/4 on motor but it ran a 6.80 in the 1/8th on motor. If you use a 1.57 conversition factor that would be a 10.67, my car weighs 3450 with me in it. The convertible probably weighs somewhere around 400LBS more than that so I would say low 11s on motor.

I think you'll run out of gear with that gear/tire combo on the spray if you even hook at all.
My heavy Trans Am went 11.05 with 3:42's and 28 inch slicks. I'm gonna lighten it up a little to see 10's.

Just make sure you go with a 90mm TB & intake.I've seen gains of 40-60rwhp with 90mm setup.

Engine dyno #'s in the sig and I have been over 750rwhp and over 850rwtq on the spray. I have a dual stage setup. I am playing with it now because I only want 725rwhp/700rwtq. Traction is needed.
