    6.2 dyno numbers

    well im going dyno the CC tomorrow night on a Mustang Dyno by the house. a buddy of mine owns the shop and is giving me an awsome deal on a few hours of dyno tuning.

    anyways these are a few details of the truck/motor.

    i want to know what yall guess the HP/TQ will be. im not too big on the HP/TQ numbers bc i want it to run great on the street/strip.

    custom cam (228/236 112+2)
    stock head gaskets

    damn, that's just basically full-bolt ons, and i think you're gonna be close to 500hp. I wanna say 453rwhp/440rwtq
    07 nnbs ecsb 5.3, full bolt on, Blown. 6.0 swap going in now, and maybe 100 shot. To be continued...

    whats your compression with milled heads and the stock gasket : 10:1- 10.5:1 ?
    i think you'll tip 400 pretty easy.. setup seems solid, dunno what your lift is, is it above .600?
    Simple: 408 on steroids!
    single digits coming soon!

    .588.602 I THINK ill have to check the cam card.
    no stock L92 compression is 10:5:1 (all the info ive been gathering) Richard at WCCH said to get a 11:1 i should mill the heads .024" but i went on the safe side so its roughly 10:9:1 id think i have no idea anyone knows how to get that figured out?

    id like to see what the truck runs before i start changing gears/stalls. im going with a performabuilt LVL2 with the billet 10.5" i think

    blown transmissions are about as useful as 97% of the guys on this forum
