Another spread worth reading. I know they kept the fuel injection but look at the power. They took a stock LS3 crate engine. With 1 3/4" headers and an electric water pump they made 493hp and 484tq. Then they added GM's cnc heads and only went from 493 to 503 hp and torque went from 484 to 497.
Then they swapped the cam for a Comp .617"/.624",231/239@ 0.050", and a 113 lsa.
HP jumped to 569 and torque to 521.
Better yet torque was 494@4,100 and stayed over 500 almost to 5,900.
Great read.
Title reads "Late Crate Update". Check it out online.

Also look at the article on the big block chev build-up and the 455 Olds.
Let's see an LS3 376 cubic inch making torque like old school BIG BLOCKS. Gotta love technology.

i have the new cc mag. reason i picked it up is because it finally has an article explaining the basic way to degree a cam in ls motors. along with ls specific cam degree parts and part no.s from comp cams.
if your a serious ls enthusiast i seriously reccomend picking up this issue.
the price alone is worth the info with illustrations for the basic cam degree steps in a ls engine article. imo

Interesting. You see the dyno setup ? Electric water pump, no accessories, Dyno headers ? (Prob use those huge dyno outside mufflers). No intake air cleaner/ducting.
Sounds like the old SAE "gross" HP days that rated the old musclecar bigblocks so high.
