You don't need any 500 cfm head to make more power on a 500 inch LS1. Who cares how much hp per inch you are making when hp by itself it what matters. The 500 inches brings the power for even a 420 cfrm head down to an rpm level that can really live on the street. This is what the bigger street engines are about plain and simple not ultimate hp per inch.
i will be getting in touch with you about a 5.4L mod motor this winter
I agree with the guy saying there isn't a head out there to flow w/ the higher cubed motors....yet.

I want to know when those heads are going to be released for public purchase.
Gonna be interesting to see if it puts down the same RWHP or close...to a 427-454ci with ported LS7 heads and a FAST/LS7 intake set-up.
I'm thinking its gonna be right around the same power. 600-625 RWHP, maybe a little more.
When do you think it will dyno?
CR?
Cam specs?
tranny?
Gears?

11.8:1
around 258/268 and .700 lift
c6 z06 with stock 3.42
if it makes under 625, i will be very disappointed. i know peak hp isn't the only factor with this big of a motor but still....
for future comparison purposes, i consistently trapped 136-137 on my 427 making 590rwhp in +800 to +1000 DA.

I am definitely curious to see what it dyno's, but I will bet that if your similar 427 combo dyno'd at 590rwp.... my guess will be 681rwp with the same heads intake combo. What do I get if I win? LOL.

^ i wish...im thinking that's close to where we will eventually end up. 675 would be nice. i think 700 is definitely possible with this bottom end if you go all out and spend the money on All Pro heads, custom intake manifold, etc. fun stuff.
results for now are 650hp/600tq
kpa reading of 93 up top with the fast 102 intake and ls7 tb
ordering a NW 102mm TB. other than that, i just want to drive the car around for a while. i probably wont race it til the spring anyway so we'll **** with other stuff later. maybe a bigger cam, custom airbridge/air filter setup, maybe speed density, cutouts etc. i dont wanna get rid of the stock NPP catback.
also, from what i was told by the shop, ERL sent us a cam they liked instead of the cam we specced out. kinda annoying if true. who knows. it definitely idles better and lopes less than my 427 did. hopefully at least the comrpession ratio is where i wanted it.

Are you sure the kpa reduction isnt because of your intake filter or tract?
Or did you log it with no air intake connected to the throttle?
If so sounds like you need at least to port the 90mm throttle. Let us know how the 102mm throttle goes with that.
In theory a gain of 6 kpa could give you 5%+ more power
What was your total timing at wot?

next plan of attack is to start with the 102mm tb and see if we need to build a custom pipe from the tb with a big filter on the end. no idea right now.
ill ask my tuner about timing when i pick up the car on wednesday
650 RWHP is pretty good though, with that top end.

ITB is currently too much of a pain in the *** for a street car IMO: https://ls1tech.com/forums/generatio...installed.html
If it was a simple plug and play application with documented gains, I would think about it.

Don't see how anyone can ask for a better idle than that for a big cube engine.
Heads flow 372cfm at 650. Modified AFR 245's.
Final Cam specs are 650lift 260 duration @50 on a 114ls on 1.7 ratio
He obviously has less drivetrain loss than we would because of that tranny he's using.
