Here are the specs: 11:1 compression ratio, LS6 fully ported heads, Lunati 4.125 stroke vrank, 4.100 bore.Cam specs are kind of general but will give you an idea: duration at .050 around 250, lift around .650, and it 's on a 111 LSA. And it's a solid roller cam.

At 2800 RPM 484 lbs/ft of torque, and 258 HP
At 3800 RPM 554 lbs/ft of torque, and 401 HP
At 4800 RPM 587 lbs/ft of torque, and 537 HP
At 5800 RPM 561 lbs/ft of torque, and 619 HP
Peak HP is at 6100 RPM and is 630 HP.
Peak torque is at 5200 RPM and is 600 lbs/ft.

 

got any links?

 

sounds intense. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

 

I take it that those are fwhp #'s? So with an m6 you would be looking at around 554rwhp.

Yep, they're FWHP. But hell, that's still an assload of power <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

 

Myron knows his $hit!! Keep in mind, they have been tuning GM EFI cars since the L98 TPI first came out, and they are dedicated engine builders and machinists to begin with. They are sometimes a little more $$, but they definitely knwo what they are doing!

 

I did'nt mean to sound like I was putting down the numbers. 554rwhp is impressive. That's a good 120 more rwhp than my little ole 346 makes.

Where is the dyno sheet?

 

There is a link on the side bar, we are a sponsor. www.tpis.com. We do no have a functional scanner right now, so I typed some of the numbers from it in.

 

Turtle, I changed your title. If TPIS has any other folks on the board email me at prostockjohn@hotmail.com and I will change their titles...

Those are some nice numbers...
