Power Ported Performance came through again and delivered my custom grind camshaft by Saturday, May 24th, 2008. I can't say enough good things about this company; they have taken care of me very well and met all of my deadlines; I gave them a deadline of just a week and a half for PPP Stage III Heads and a full Custom Grinded Camshaft and he didn't even blink an eye. You might think, "Ah, a week and a half isn't that bad at all!" But - one thing you have to remember - I'm on the west coast, 2200 miles away. And they still delivered as promised, when promised. I couldn't even get this kind of service out of our local speed shops.

The PPP Stage III heads are beautiful, they are everything he said that they would be and more. I can't wait to get this thing and bring her back to life. I lost her heart beat yesterday, but she'll soon be jump started.

The special order Precision Industries 3000 Stall 3-Clutch Torque Converter will be delivered on Tuesday, just as Power Ported Performance promised.

The following pictures are of PPP Stage III Heads and a PPP Custom Grind Cam. I just had to include the cam box in the pictures - gotta love their sense of humor! "Mango Warrior, Mango Powered.."

what are the flow rates on the 5.7 stage III heads, vs the flow rates of the 6.1 stage II heads?

**PPP-Tim** · #3 (**permalink**) 06-02-2008, 08:14 AM

5.7 stage 3 heads will flow approx. 360+cfm vs 6.1 stage2 heads 380cfm. The larger valves in the 6.1 and increase runner size help them outflow the 5.7.

Both the 5.7 stage 3 and 6.1 stage 2 heads have larger diameter valves then stock.

Those are great numbers on both. I thought the 6.1 would have a larger advantage, but good numbers nonetheless.

Stock vs stock= 6.1 Heads are way better.
Stage 2 5.7 PPP heads vs stock 6..1 = close to each other
Stage 2 5.7 PPP heads vs Stage 2 6.1 PPP heads = 6.1 is much better
Stage 3 5.7 PPP heads (with increased valve size) vs Stage 2 6.1 PPP heads = alittle closer

Our stage 3 5.7 heads are the highest flowing 5.7 units I have seen on the market.

Thanks for the comparison tim. I appreciate that, really cleared it up for me. Do you guys have a cam grind specifically for the forced induction applications or will i have to get a custom grind?

**PPP-Tim** · #7 (**permalink**) 06-04-2008, 07:32 AM

We have a turbo cam for 5.7, 6.1, and 426
We also have a twin screw supercharger cams for those same engines, and cams for centrifugal type ( Procharger ) superchargers. Each engine displacemnt has its own specific grind for the type of FI you choose.

In summary: Yes, we have a cam for you.

Thanks,

Tim

Great info Tim, thanks. The hardest part for me will be giving up the LOPE lol. If i were to go with a more lopey cam (such as the track warrior xl) as opposed to the FI cam, how much boost would be made? Or would i actually lose power. I know on some applications you can lose power without a cam that has been grinded to specs for a FI application

With turbo applications- you typicaly stay away from cams with a huge amount of lope. With a supercharger you can run a cam that has way more lope.

The actual determining factory to how much lope you can easliy run will come to transmission choice. With the auto, you can only run a certain amount of duration before it becomes hard to drive and tune. It will want to stall when put into gear, so you then have to raise idle to try to help it. Then what happens is that the idle is so high that you cant hear the lope of the cam anyway. It also helps if you have a higher stall converter, like 3000/3200rpm. If you get a manual car you will be able to pick a more aggressive cam.

ok i got ya. I didnt think of it like that (auto vs manual). I just assumed that it was the same. But i can see why now that you said that.
