Ok, I'm having my setup fine tuned and Dyno'd May 15th...

the motor is the 383 stroker, 10.3cr
Dart Iron Eagles, 200cc runners, 72cc chambers 2.02/1.60 with 1.6 roller rockers
Comp Cams XR288HR, 236-I,242-E @0.050, 106 centerline, lift .555-I, .576-E, 110lsa
Edlebrock RPM AirGap dual plane, with a 1" 4hole tappered spacer, AED750HO
Hooker LTs 1 3/4x3", going to a Xover then spintechs and dumped b4 the axle

Going thru a built 700r4 and 2600 stall with 3.42 gears.

The motor dyno'd at the builders at 486hp @5800/478trq @5100 without the carb spacer

This is going into a 84 Camaro Z28, still near the original body weight, no fat trimming has occured yet. est @ 3400lbs

Any guesses on final rear wheel numbers and projected 1/4 mile?

Choice of rear tires will be Nitto DR's Nt555r 275/50/15 or
M/T ET Drags 28x10.5x15

With a 3.73 or 4.10 i think you could run low 11's.......i'm not so sure how the 700r4 works with first and second gear ratio.
11.20-11.50 is my guess.

First will be plenty deep, I think weight will be the issue and if it hooks up ( Nitto's Blah) low 11's here too
