Here is a LPE C6 in the same boat w/360 tq. I suppose 424HP is OK these days. Blazeone hit the nail on the head about the trade off. Peak numbers are far less important than the actual curve itself. But peak numbers sell packages (whats the pckg called?) and what a sacrifice, look at the size of that cam. Please tell me that the slugs were flycut and the heads were shaved because that log needs much more dynamic/static compression. How much time do you spend 6000 rpm+?
I assume you have 4:10's. I can't imagine building/ordering a street motor and not making max torque the #1 priority but thats just me.
Take it to the track and see what it traps.

Having those kind of guys running around here with the resources at their disposal is a HUGE benefit.
I've seen it happen too.
There are two local guys in a similar (not quite the same) boat.(Monster cam stuffed in an otherwise stock motor/gear shaking their heads back and forth about why their car "Feals slow")
Go to the track.

360 rwhp is fine for a H/C package designed for a street car. Not everyone wants a lopey cam that idles like crap. JMHO.

I'll be looking forward to it! And there's nuthin' wrong with a big bumpstick, as long as you've got the right gearing and compression. I think LPE bumps the CR up to about 10.8-11.0-1 in that package so you're OK there. In fact, IIRC the duration on that cam is under 230 w/ 114 LSA so it's not like you're running anything real radical. Still, I bet 4.10 gears would make it scream.

dude stock cars with bolts on make 360rwhp
if u are looking to make that much power, i will sell you some stock ls6 heads and cam
point is with a cam as big as he is using, he should be making more power than his car did.
There are cam only cars making about the same power with a cam that big.

I'll venture to guess he is unfortunatley at stock compression & even quench for that matter. Just look at his graph.
BTW I did not mean to call out the combo you bought. Obviously all that matters is your happy not how it compares to other combo's or cams. Input and learning is all this place is about so please do not take anything I or anyone says personally. Four pages of "thumbs ups" does nobody any good.
Mark what heads did you get ?!
