I just got a set of PP stage 3 "ls6 style" heads with the "race port" hand finish option, 2.08 & 1.60 valves, and 59cc chambers. I am looking for 10's. Its an all bolt on m6 car, 346ci. Any help is greatly appreciated. Has to be n/a.

 

I know Lynda has gone 10's with her PP LS6-style race ported heads. Her car is also set up very well, and weighs about 3400 lbs. It's got the TSP Magic Stick, IIRC.

IMO, it's going to be very difficult to hit 10's in a heavy 'vert with just heads/cam. My 'vert weighed in at 3800 lbs (with me - at 170 lbs - in it). You're going to need to lose weight, and have a well above average horsepower setup (likely 470+) to overcome the 3500-3600 lb weight you're sitting at.

Whatever cam you get will probably need to be big... mid 230's duration intake, low 240's exhaust, I'd say.

And of course, you'll need a 12-bolt with 4.56 gears, a serious clutch (I have the Ram VDS/910), and a stout driveshaft - along with slicks.

Good luck!

 

I already have the 12 bolt, suspension is already set up, spec 3 just went out (couldn't handle low 11's) and vds/910 will be here by the end of the week. If the car makes the power, I'll get it into the 10's. I just need to know what cam to use to make the power.

 

well you already know what I said in the other post in Internal section

 

WOW, the spec 3 didn't handle 11's.... how long b/f you really tore it up... anyhow, 10's with h/c are very seldom... get a 150 shot and see what happens...
