Final tune of my LS3 427 Camaro

How about some details on what kind of work you have done ?? Inquiring minds want to know . Gota love good old American Horse Power
 
That has to be one mean machine. With that kind of torque, traction has to a problem when you get on it.

Well I pulled the original LS1 motor and started fresh.

Its a brand new LS3 block from the 08-up Corvettes, 6.2L. So bare block came from Scoggin Dickey, then it went to my engine builder.

There it was mated up with a 4.1" Forged crank, one-off Wiseco forged 12:1 compression pistons matched to the heads/cam choice with valve reliefs cut into the pistons, TSP ported/polished 5-angle L92 heads (basically LS3 heads with solid valves which are better suited to high hp and high compression than the stock sodium filled valves), TSP hydraulic cam (251/259 on 111 lsa and a crazy .661 lift), loaded the heads with Yella Terra full roller rockers 1.7 and Livernois motorsports .690 double springs, hardened pushrods, forged connecting rods, LS6 oil pump.

They decked the block, bored it, stroked it, balanced it, and blueprinted it. Running a nice 12:1 CR, and it will spin safely up to 7250 RPM, redline set at 7100 for safety (not bad for a big V8). Resulting cubic inches put it at 427ci or if you like.. 7.0L.

As for the bolt-ons, its got a L76 90mm intake manifold, Nick Williams 90mm billet throttle body, Kooks 1 7/8" headers with 3.5" collectors, 42# injectors, 100mm intake lid and Z06 MAF, dual electronic cutouts just behind header collectors and in front of the cats, 3" true dual exhaust with X-pipe and magnaflow mufflers, full tubular upper and lower A-Arms from BMR (full adjustable), tubular K-member from BMR, additional BMR: subframes, adj panhard bar, adj lower control arms, adj torque arm. Trac-Tek relocation brackets, BMR 1" drop springs, Strano Re-valved Bilstiens set specifically for BMR 1" springs, stainless brake lines, 6-point Wolf roll bar with door swing outs, 5-point Stroud racing harnesses with camlock and crotch strap bars.

Trans is a built D&D T56 with every option and upgrade except the Viper shafts, LS7 clutch, and custom widened stock SS chrome wheels in the back so they are now 17x11 and running 315's out back.

I think that covers the majority of it lol.

Thanks. Yeah on street tires its a handful. It spun the tires shifting into 4th gear at Sacramento Raceway @ 120 mph right before the finish line. 1st and 2nd were completely useless lol and I had a couple hints of traction in 3rd... basically I was spinning the tires down the entire track, and never even got to full throttle.
