HPE megadeath cam NEED HELP!!
Like I said, go over to LS1GTO.com and search over there. Everyone and their third cousin's sister's grand daughter is running that cam. You can check out what heads they are running and what numbers they are making. You're not going to find what you're looking for here.
The HPE Megadeth has been around a while and uses XE-R lobes. Folks used to run it years ago here. But it's a reverse duration camshaft and F-body's have terrible exhaust setups compared to GTOs or Vettes, so our cars don't love it as much...
Why would he not be able to find what he is looking for here?
LS heads are LS heads as long as it's cathedral versus cathedral? Valve events are also valve events they don't change due to what car they are being used in.

but it sure is cool to post the youtube vid of your car idleing how badass is sounds.
IMHO, Id get a smaller cam and a good set of heads. Power down low will make the car much more fun to drive, and having a wider powerband can put you in front of cars with higher peak power.
AI ported 243/799s and a mid- high 230s cam with the correct boltons will make some serious power, and not just peak. It will make power down low.
My wife's car is running a mid sized cam (EPS 227/230 .614/.609 113 +1) with stock 799s and makes 330ft/lbs @ 2500rpm.

so when i pick up my stage 2 ported 243s (heads will be bare) and upgrade the rockers/lifters/springs/valves to match the cams requirement then i should have no problem with this
I think he was talkin about the vett and gto have better exhaust. Meaning they don't use y pipes and go into a single exhaust like a f body. Its a better cam for a car with true duals. A cam like that needs a good exhaust system
well an x pipe isnt really that hard to fab up or just plain out purchase one, so far for exhaust i got LTs to a CME but i wanted a true dual for a while and since this sparked up my motivation for my car so i figured after i gathered all my parts i'll have a semi build going on

Verdad Gallardo Yes the true duals is what I refer to. But the head flow on the ls is still heavily biased to the intake. It can make power, but most would be better served with a cam matched to their heads.
Well I saw a "D" pipe on another thread on here which is essentially a X and a H pipe as one in holy matrimony. I was going to pick up a fast 90/90 for my new intake. I got a whole laundry list of things I need for this upgrade the one I'm worried the most is the Heads and it's internals
Speaking of heads Martin@Tick I was looking for the valve train package and springs you speak of but couldnt seem to find them is the correct ones I need, although I did find the SLP dual timing chain which I will be purchasing
Go back and check now. If you're running stock rockers use the Platinum .660" spring kit. If you're currently running after market rockers use the Max Pressure .650" kit.
Alright so I've settled on the options for the heads and it's respective internals they will be ported 243s, the max pressure .650 springs since I'll be using aftermarket rockers. But I am troubled which rockers to use, 1.8s will lower my comp right and some were saying stick with 1.7s so now what? Which ones will suffice?

1.8's will raise the lift, the duration, and make the ramp rate of the lobes too aggressive for the springs you will be using.
Use 1.7 ratio rockers.

alright so i finally decided on the Heads, i found a great deal and a good way to afford some great heads, instead of the ported 243s i will be purchasing Dart Pro 205cc heads 2.02 intake 1.60 exhaust 62cc chambers does this sound like a better choice than ported 243s?
