302hp..

i think its pretty shitty LOL.. i need some quarter-mile guessings..

how many hp loss will give me the Stall..

sorry about my english!

this was a 3rd gear run

 

Well if you would spin it up to 6500rpm or so and let it peak,you would have higher numbers.5200rpm where yall stopped,it was just getting started.tq curve is nice though.very broad

 

Yeah why did you cut off so early in the run? These motors love to rev, so let it

 

I made peak HP with my cam only at 6500 rpm

 

Thats the point, he shut off at 5200 rpm

 

thats true.. i wasnt driving or operating the dyno they just told me the number so.. that cam should peak at what rpm..

its the stall converter making a bigger drivetrain loss...
how much RWHP have a COMPLETE STOCK silverado

 

my truck did 306hp with the k&n, edelbrock shorties, spacer, u/d pulley, stock 3.73 and I did it on 22' rims. and its an 09 rcsb

we basically had the same truck with the same bolt ons except you have a cam and stall. So im guessing you could of got some better numbers if you hadnt shut it off so early. I would expect at least 25 more hp out of that.

 

the TB spacer is pointless... shorties are pointless also .. my truck ( with the 5.3).. made around 360hp and 330ish tq IIRC 224 cam long tubes, intake and tune ,converter locked

 

:werd on what Daryn C said.

get some long tubes, throw some more RPMs at that thing and have fun! i say 330 easy
