Okay- cars been pretty much the same forever, and the cammed, exhausted, nitroused LS1s around here are owning me.
My combo has been the all forged sportsman block 327 (8.5:1), with e cam 1.7s and stock 95 cobra throttle body and intake, bone stock iron gt-40s with better springs, complete Aeromotive system with 42s and Pro m 80. FMS shortys offroad h and spintechs with tailpipes. All MSD with 6A. PA is a Vortech S-trim at 15psi, 2.95/6.87. The car passes CA smog in this fashion.
Last dyno showed 476 rwhp and 468 rwtq a tad shy of 6000 rpms (air fuel went to 12+), and last track outing with a best 60 of 1.8, the car went 12.1 at 120, and we revved to 6700 no problem.
Its had the same autologic chip forever, and the tune has remained the same, even since replacing the fuel system, so I think the tune could be alot better. I just bought a PMS for it so the tune should become alot better. I also picked up a pair of AFR 185s (60cc with ed curtis springs), and will pick up some compression since my gt 40s are 65cc, and bought an Anderson B-41 cam. I will match an already ported cobra lower I've had around to the heads and clean the heads up some. I will be putting a 2.85 pulley on the blower and spinning the piss out of it.
My question, for those that have similar setups, is the gains I will see, I'm thinking 50 rw, but have heard smaller numbers, and larger, any guesses, since the car will be down and not on a dyno for a month or so.
Thanks guys/gals, sorry its so long, and I usually hate on these "guess" threads, -Rob

I'm thinking you'll see at least 50 horsepower as long as the cam can make the 185's perform as well as they can. I would ditch the cobra intake for something that flows better. At your power level and with a more agressive cam you might want to look into doing an early model computer swap...Remember if you can't hook off the line you'll continue to get owned by the chevy boys. Might want to look at the suspension as well if you haven't already.

Oh and you'll most likely need to step up injectors size as well.

Somday the intake will change, but money is always limited, and I have to use what I have.
The suspension consists of Lakewood 90/10s up front, Competition engineering 3 way adjustables out back (on 50/50 right now), drag springs, air bag@25psi, welded subs. I have all stock control arms, but I have some adjustable weight jackers with sperical bushings, and I was going to box my uppers and have spericals for those too, just too lazy to install that stuff.

Still have the vibration, so Im going to pull the trans with the motor and make sure I didn't crush the pilot bearing or somthing during install.
Either way, I have an ATO built C-4 with manual valvebody on standby.

You could leave your motor the way it is and put on full rear suspension and you'd be in the 11's all day. That would stop them chevy boys from owning you. I know you wnat to hear more about engine mods, but seriously bro, you NEED good rear suspension to go fast. Period.

You may want to work on your driving before you waste time with more mods. ![[Wink]](wink.gif)
And you do know that with a 2.85 pulley you will be overspinning that S trim, right?

you can sell your cobra intake for 300 and pick up a used edelbrock rpm for 350
