Lifted07Duramax

2000 LS1 stock cam, 5.3L stage 2.5 heads, b&b shorty headers, fast 90 with ported ls2 tb, UD pullies, 85mm MAF

398/391 with a way more torque down low than any cam only LS1
It did hit 402/393 but with a tad bit of knock up top so he richened it up to 12.4 I think

I hope to have the dyno graph up in a few days

Congrats!! That's damn nice and great tracking of gains along the way. Thanks for sharing. Must be fun to drive. Longtubes in the future?

Yep probably XSPower headers
I'd expect to hit at least 410/400

Nice, so how much HP/TQ is the cam going to net now? I like the way you went through with the progression of mods. Sheds a lot of light for us.

No clue, Id hope to atleast hit 450/420
Ill be going with an EPS 226/230 113 + 2

I knew I could only do these mods one step at a time and that in the end I'd have heads and cam so I did the heads first to give everyone a look at what a heads only car can do.

Anyone know what spec cam it would take to get a LS1 with stock heads up to 410/400 with all other bolt ons?

I've seen them hit over 400rwhp but usually 370-380 for torque is it

Nice numbers! I'm hoping to get some port and polished 5.3 heads for my car soon...

I think mine are milled 61 maybe 62cc

nightster

The buddy I'm getting mine from had them milled as well, I'm not sure how much.

I just looked at your numbers, and how in the world are you putting down those numbers without cam or heads?
I've never seen a C5 come close to those numbers with those mods

Interesting. Those numbers are awesome with a stock cam. I bet this setup would put a hurtin' on a lot of big cammed cars with stock heads and **** tunes.

I was pretty baffled myself. The uncorreted numbers were even crazier. Here's the link to my thread.

I like the comparison and difference of gains. We tested like that about 8-10 years ago. Only difference is it should be SAE correction since STD is always a higher # than what most people compare.
