219 int and 228 exh i believe is the spec on it at .525. Ls6 valves, and an Ls6 intake also, what needs to be done to the heads to make it to the 400 rwhp mark or beyond? Only other mods are hooker headers with y-pipe and a corsa cat back with no cats. Also how much tunning is gonna be involved and what is recommended for the best tune?

You will probably need a fast90/90 and good heads (afr/etp) etc to make that with the hotcam.

if your gonna run a good set of heads then upgrade the game. there's no point in running a cam that wont take advantage of the added air flow. i've rarely seen any good H/C packages with the hot cam. cam only w/ bolt ons i've seen ~380rwhp. tuning with this cam wont be much different then any other cam, you'll want to optimize your timing curve for best power and driveability.

Have that setup, but 6.0liter intake rather than FAST or any TB mods. Hit 347.6rwhp witht he hotcam and storebought tune but remember, I've got like at least 23% drivetrain loss - so I suppose I'm hitting somehere around 425hp at the crank.

you're going to need a set of heads to get your hotcam to 400rwhp. i got 375 rwhp, without heads for me to get to 400 rwhp the only thing that i could count on would be a ported TB, electric water pump, and underdrive pulley... i doubt that would get me there.

...ya know, Nitrous would get you there,... and then some!

The hotcam is a niche cam. It fullfills certain needs, but not all. If your main concern is rwhp numbers, look elsewhere.

To partially answer your question, with LT headers, ORY, hooker catback, LS6 intake, my bottleneck was in my intake.

I agree, so many cams better than hotcam and runs alot smoother too. 224/228 is a great choice and will make good power.

Would it be cheaper to go with new heads or do up the ones i have i do have a local machine shop local.

I do plan on running at least a 100 shot after the cam is installed id like to see 500-550 rwhp after its all done, but getting the 400 rwhp mark na would be very nice.

dude, you start out with like 20+ rwhp more than us ls1 guys.

on a side note - that doesn't seem like much of a cam when using an ls6...i've seen 224 cams put down those numbers in an ls1.
