GM Performance Parts has a package now that has the 295 hp 5.3L with a Hot Cam making 332hp @5500 and 352 ft lbs at 4600 rpms untuned and on 87 octane and still on the stock 9.5:1 compression at the flywheel. It makes 300 ft lbs or more from 2000 to 5750 rpms. Just thought some people would like to know this.

 

Good info, keep up the good work!

 

does the power start to taper off or drop off at 4600rpm or is there another reason the arent taking it higher

 

HP stays flat from 5300 to about 6000 for the most part. The numbers I listed where peak but they took it to 6000 rpms.

 

sounds like a candidate for a ls6 intake....

 

Is this a carbed engine like their 440hp 6.0 crate engine?

 

Nope, fuel injected.

 

I read the cam specs, it didn't look like a hot cam to me. I believe it was the hotter 5.3L cam (L33) and just poorly advertised. Page 70 in the new book

Cam:

.467" I
.479" E
196º I
201º E

 

Yea I read that but figured it was the stock specs b/c it list the HotCam part number on there but who knows.

 

Do you have a link to this?
