Still have the GTO?
11 Bravo how much tq differance do you think the N/A will have vs the FI?

11 Bravo : usually these is an Avg of 20+ rwtq differance between na/FI and as the FI gets higher there differance becomes greater compared to that of the N/A including a S/C
a 500 rwhp turbo car is gonna be close the same tq as hp and in alot fo cases they produce more tq than HP
here are 20 pages of N/A dyno numbers , granted there are a few odd ball numbers in there AND some of the numbers listed at boosted as in FI numbers

Let me make something clear when I tallk about FI i am talking about Turbos (if anyone hasnt already figured that out) unless stated otherwise
the boosted list

while yours not doubt is 100% user friendly are you in the 9's n/a?

No, I sold it to a guy in England. I'm thinking about doing another one now though....
I think you guys are going to be susprised at what the NA game will bring in the next year or two.
BIG cubes make a car very driveable. Forget about poor street manners. I'm thinking:
LS2 402 or larger
CNC L92 Heads
Ported L76 Intake
Custom Cam
SCR 13:1-14:1
DCR 9:0 or more
E85
600-700rwhp anyone? And it can be very driveable. I bet you could hit 600rwhp with a "small" 238/242 LSK lobed cam, and have gobs of usable power all over. A 427-455 cube motor could probably crack 700-750rwhp with an individual runner intake. All speculation of course but we will see how far off it is pretty soon.
Basically what I am trying to say is NA can be a very formidable setup if done right, and it will be cheaper than forced induction. Although if you want to max out both setups, of course the boost will take you further.

550 rw can get you into the 10's completely streetable NA with minor weight reduction. Not uncommon at ALL with a lsx stroker N/A.

Top end on a stroker is nasty. I would put money on a 500 rw stroker destroying a 500 rwhp blown stock motor any day of the week.

i never drove a big cammed 402 but ive had a 346 with heads & a g5x3 which is a big cam for a 346 and it drove totally fine, totally streetable. I dont understand where everyone thinks NA is so unstreetable. maybe if your talk 14.1 comprresion with gigantic solid roller, then yea ok.
I also had a twin turbo with a stock cam & heads and it drove like a stock LS1.
if your looking for smooth 600 plus HP go FI but if 520-550rwhp is all you want Id go 402. watch the videos of a NA 500rwhp C6 z06 pull a FI 600rwhp KB cobra. Ive seen this twice so far and they were different cars & drivers.

I dont have the graph from before on hand, but it was making 420 ft/lb at about ~2300 rpm. IT's getting a full tune in a couple weeks and i'll post the graph for you.

There was an article in CHP recently where a forged mild streetable cam 402ci made 580hp and cost just under $10K U.S. to build. A procharged, forged LS1 will make serious power depending on how much boost, for about the same money doing it yourself and rebuilding your LS1 motor. You'll need to find a new set of heads though, but not totally necessary. To keep the cost down, I would look for an LQ9 head because of the 72cc combustion chambers. These can be found on the 6.0L Cadillac Escalade and they are aluminum and can be ported easily.
