    motors a 454 bored to a 468{at least thats what the paperwork says LOL}
    edelbrock alum heads
    performer rpm intake
    demon 750 carb
    comp roller,not 100% positive on duration,but when i bought the truck there were two cam cards,and since the truck sounds rowdy'r im guessing its the larger cam ,which specs out to a comp XE 284
    1.7 roller rockers,2 inch primarie headers,3.5 inch true dual exhaust into flowmaster 10 series race mufflers,then dumps right in front of the rear tires
    full MSD ignition,dist,cap,rotor,wires

    right now im having a few rather serious tuning issues,and cant seem to tune around them,and im tired of tracing it down,so this coming weds i purchased 3 hours dyno time to get it straightened out.

    heres what the dyno guy wants to do.

    5 full pulls,and wideband 02 monitoring at just about every speed/rpm

    i also get a full 1/4 mile run on the dyno,as well as a 4wd dyno run,see how much hp im losing through the drivetrain :haha:

    oh,man with the holiday and **** i forgot about posting the results lol,i havent even taken the vids off the camera or the pics

    anyways, in 2wd i put down 419rwhp and 501 tq

    with a 75 shot of juice on the barry grant single stage nitrous plate,it put down 499 hp and 622 tq.


    i never tried it in 4wd,aparently the balance was off on the buckshots amd the dyno guy didnt like the vibes from 40mph+ wierd though because it doesnt vibrate goin down the hiway :shrug:,ive been concentrating on work,and racing r/c touring cars on the weekends,ill try and get the vids up this weekend.

    the msd box was actually causing the problem,it was kicking in the soft touch rev control at all rpms. he threw on his personal 6al box from his 71 camaro,and it ran great,so i just bought a new one from the shop next door.

    my jetting was a little bit off,but not bad for just tuning it by ear/drive hell i didnt even time the thing with a light,just by sight and sound LOL.
