Dyno numbers.. So I finally got to the dyno today. Pretty happy with the numbers. Surprised how consistent the pulls were across different timing curves
Heres a quick run down of the setup
Ls6 block
Stock bottom
Comp cam 281LR HR13
Vic jr intake
Holley HP ultra 750 carb
AFR heads 205 cc springs matched to cam
Comp cam push rods
Trunion rebuild
Doug Thorley long tube headers 2.5" exhaust w Magnaflow straight thru mufflers
Cut outs
T56
3:73 w 12 bolt
MY PEAK 463.3 RWHP @6300 rpm
But only 415 lb ft of torque @5300 rpm
Now heres where it gets tricky for me personally.
I bought some cut outs n expected a slight increase (figure for all the loudness better get something out of it) but nothing. No increase or drop
And I tried timing curves from 24-36 degrees and as you can see from the pics of the graph.. Pretty much dead on. It peaked @ 28degrees. But as i raised n lowered it only real difference was in torque.
Kinda curious as to what you guys think, any ideas or tricks to gain a little extra?

Not familiar with that grind but that is nice numbers. If only the automatic guys could pull that high just to satisfy them. They allow the converter screwing up the numbers to upset them.

Right?!? I gotta a buddy with a similar setup, but hes about 30 hp under me.. He cant get me in the streets.
