i may be getting some stock 5.3 heads and ive been looking at the asa cam and some 1.8 rockers how do you think this setup would work together im not wanting to rev past 6 grand dont really care what the peak numbers are i just want a nice sounding idle and good torque thru the rpm range. should i be 370rwhp range or better what should i expect

Though most will say get a custom cam and save the money on going with 1.8's, I think that if you did go that route you will have a stout combo.
The ASA cam .525-.525 226-236 110ls will be .556-.556 226-236 110ls w/1.8's combined with 5.3l heads added compression should be pretty snappy down low with good power under the curve. It will lope pretty hard too. The big exhaust split should work well with your MAC mid length headers. I'd expect close to 400rwhp, probably 390ish. You may want to consider getting those heads ported or some stock LS6 heads and be about 420rwhp.

FWIW, a friend of mine has the ASA cam in his camaro. LS6 intake, lt headers, stock heads. His dyno graph is strange, huge torque (400+) across the most of the pull, but near stock hp. Ran on a mustang dyno. Idle sounds awesome and very good street manners.

Yeah I will definitly get the heads ported with bigger valves plus it should be very easy on the springs and valves 400 rwhp sure does sound like fun

That is not possible. Horsepower is a mathematical relationship derived from the torque value.

It is possible but your redline would be under 5250 or whatever the hp calculation number is. Think diesel. Huge torque little hp due to the low rpm. Either way something is wrong with that car unless is was built for a class where hp is limited but torque is not. (thinks wrx)

Given what he wrote below it realyl isn't possible. If he is making 400+ torque anywhere, he would be way above stock power levels.

Oh I agree 100% that it is incredibly unlikely but not unpossible. :-p

I'll bite. The guy above is claiming 400+ torque and stock power levels. A stock LS1 never makes more than 340 fwtq. Therefore, if he makes 400 tq anywhere on the curve, he would have to make more power than a stock LS1 at that point of the curve. In this example it is actually unpossible.

I guess I should have worded my post better. His last pull was at a dyno day about 3-4 yrs ago with a local club, about 16 cars ran that morning so there was nothing wrong with the dyno. I dont have a pic of his graph but from memory the torque curve was nice and flat and the torque came in early. And yes, the lines intersected on the graph but I just dont remember at what rpm. HP was in the 340-350 range and I meant stock internals, he has lid, intake, exhaust, sd tune, etc. TQ just barely topped 400, 404 if I remember right. His pull had most of us scratching our heads at the dyno day how it broke 400 tq with a relatively low hp, especially on a low(er) lift cam.

Calculation: [(torque x rpm) / 5,252] = hp

Tried the equation with a couple different rpms:

380 hp @ 5000 rpm
342 hp @ 4500 rpm
304 hp @ 4000 rpm

May car with a Hotcam made 381/373 with a torque peak at 5000 rpm and a power peak at 5950 rpm (which would have yielded 336 rwtq at that rpm). The ASA cam should be superior to the Hotcam particularly in the upper rpms. Seems like it should have done better. However, every car is different.

Yeah I dont know man, talked to him today and he said it put down 343/406 and he was going to try to find where he put the graph. Again, it was a dyno day, mustang dyno, nobody else seemed to have off readings. I guess the operator could have set up the dyno wrong on just his car.
