226/234 @ .050 628/604 113 lsa

With this cam and an LSA supercharger with a 2.55 pulley, it put down 629HP/620TQ with 11 psi. The kicker, at or off idle, before 2000 rpm was 520 lbft of torque!!! Stock ly6 except a cam and spring swap. What do you guys think? Granted it was in a Chevelle, I think?, What do you guys think?

Stock blower? If everything else is stock I'd say those numbers are great. My V bone stock put down 455/450. I would love to get close to those numbers with just a cam swap lol.

Yea, stock blower with pulley swap. 91 octane. The fact that he has that much tq down low is crazy! For a truck that would be insane!

Garbage, will never work.

That cam has 4.00 degrees of overlap.

So what that means is,

It chops a little and it keeps cylinder pressures manageable.

If there was less overlap, it would probably make more torque down low but at the risk of higher cylinder pressures.

For a truck, you'll never see that number even if you swapped that drivetrain in.

But it would be close....and fun.

He could have went more, but didnt want to run meth. Heres the vid.

If thats a true dyno pull, that's totally awesome
for a stock motor with just a cam. is it a 5.3 or a 6.0 ?

ly6 = 6.0

Horsepower: 385 hp @ 5600 rpm
Torque: 400 lb-ft @ 4400 rpm

6.0/lsa cam/2.55 only really good numbers! c7z's are only putting down 550ish to the ground

kinda has me rethinking my 6.2/boost build

4 gen 6.0

What boost build are you doing?
