Hey Bill what math are you using? .25% (331*.25 413.75/370*.25 462.5) trans loss? Ive always used .20-.22

Hehe!!! That is rwhp hp/ci. Crank hp/ci is: 1.27!!! ;)

(Like Todd said, rwhp is what we're really interested in!)

Surprised a built up 5.3 swap but no long tubes!!! Edit duh you are in California not exactly CARB certified to put in long tube headers relocating the cats and all.. So move to Montana and Swap in some Stainless works long tubes and a new Dyno tune and that engine will ERUPT the torque curve. May have the first official 12 second NA car!!

I believe Joe's stroker has done 12's N/A. My BB/S did it too, long ago.

Ha Ha legend has it that "No 4V Panther has done 12's N/A" I suspected this to be crappo!!

I think that the CARB should give a waiver for a set of Stainless works long tubes if you show em this dyno graph..

Look man.. That engine is BEGGING to be let loose :) (Plus maybe degree the cams too?)

The cams should be degreed, any respectable shop will always degree them upon installation. However, most don't know where to put them to acheive the best powerband. They assume the specs on the cam card is where they should be...how wrong they are.

Most recently I've ween 13% for manuals and %17% for automatics, but who knows how accurate that is.

So Todd what do you think I could do to extract more power NA? Should I can those cams and do a custom grind? I have no idea what the mystery cams are...other than what Mark said he thought they were (106400). They were billet so dunno. I may down the line have AED check them but right now they'll have to do as they are now.

I always hear discrepancies when comparing Mach I auto vs Marauder auto...essentially 15-18% on the Mach vs 20-25% on the Marauder....dunno:confused:

NICE! Don't be disappointed! Those are nice numbers! Think of it this way: 331 rwhp and 370rwtq is about 414hp @ the crank and you're getting about 1.18hp per ci. That's great! That torque is awesome too! 300rwtq @2,250 rpm! Now supercharge it!!!

P.S. I was 5hp off and Casey was 2nd @6hp off. ;)

You win THIS time, Obi Wan.....:cool:

Hey Bill, yeah those are good numbers the torque is great! You and Casey are right on point!! But yes pretty happy drivability is even better. Gone is the throttle tip in dive in RPMS and idles again like OE stuff. Cant complain a safe tune for Cali fuel. The tuner thinks the intake and cams aren't a good match because it peaks at 4875rpm. But she'll have to do for a while.
