Oh, sorry. I guess realistically, I'm looking at 25-30 across the board huh? Hopefully more for how much it's costing me. I think the tune alone will speak wonders. And the heads are really just what I need to make this thing scream.
i think you will be happy with the afr heads, i had a set on a sbc 383 and they are awesome. I went with a ported ls6 head on my 402 for now. I will step up later, I am also taking the car to speed inc to get tuned (5 hour haul) I will be there on July 30. Good luck
maybe start with the basics, check MAF NEW PLUGS, AIR FILTER, A/F ratio is it 12.7:1/ 13:1? good luck, just my 2 cents before you start throwing big $$$ to fix. oh how high are you revving RPM'S ? i could fax you the page from the book dyno proven performance on FAST intake, pm me a fax #.

I don't have a fax #. I don't doubt that I made a good decision with the FAST 92, my setup is just not primed to take advvantage of it yet. I believe I will see incredible gains with the AFR 205's and especially with Speed Inc. doing the tuning, i'm really excited!! I'm trying to be optimistic with the expectation of 25-30 but secretly i'm really hoping for quite a bit more than that!!

I'm running the stock maf, I had a Granantelli but Speed inc. said to have the stock maf on it for tuning purposes when I get it to them. A/F ratio is good, K&N FIPK.

i know you are doing hella work already, and you dont want to hear anything about another part, but....
What about changing out the cam while you are having all that work done? YOu have a very mild cam, and it would be in your best interest (you want bigger nuimbers) to swap that out while the motor is being played with. I dont know what you want as far as duration goes (drivability, where the power comes on, etc), but how about something with a lift aroung .600 and perhaps more overlap\tighter LSa?
Take advantage of those new heads and Fast92, and a cam is a relatively cheap by comparison mod with all you are doing.

that question has no single answer because of the many variables. Tuning is a huge issue with that, as a good tune can make a big cam drive like a dream, or a shitty tune can make a small cam (like yours) have shitty drivability.
As a reference, take what i drive for example. I am not turning this into a chance to talk about my setup, just want to give you an example of something i can speak first hand about. I have heads and the rest, and my cam is a 236\240 .610 .610 111LSA.
Most would cal that a pretty good size cam, tight LSA, lots of overlap, etc. Most people would expect it to be a shitty DD cam. I tell you what, it drives beautifully. The only time i get bucking is if i drive it in 1st gear with real low rpms when i first fire it up and it isnt warmed up. The only other noticeable effect is that putting it in 6th gear doing 45-50mph like when stock isnt a good idea, as you can hear it (barely) bucking slightly due to the RPMs so low (under 1400). THATS IT!!! It drives beautifully. No stalling, isnt idling at 1k or anything, doesnt buck or surge all over, etc. Other then those 2 VERY VERY small issues (one of which is due to driving it while cold, and goes away once warm and the other is just due to trying to drive in the wrong gear), i have no issues with drivability.
So thats my experience. You have a manual trans, right? a cam in the high 220's low 230's would be DD without issue with a nice tune, i would imagine. There are many on here you can ask, as well as the dudes at SPEED INC.

Thanks for the info, i'll talk with Larry about it. It's just that I'm pretty much maxed out on funds for mods after the heads and installation. I almost went with Patriot heads instead of AFR 205's just to free up some cash for a Tex clutch but I don't want to regret not getting the best heads for my dream car, know what I mean? I imagine the cost of a cam like yours would be around $400? I wonder what the install would cost me?

yeah, cams usually run $350-$425 new. As for the install, i am not quite sure. I believe it is cheaper to do while having all that other stuff done at the same time, rather then just doing a cam. And you could recoup some of your money (200-300) by selling your cam after. I know how it feels to be tapped out. However, if u can manage the extra couple bills, and u and ur builder feels it is worth it, go for it. witht he other stuff you are doing, it doesnt make sense (to me anyway) to have such a conservative cam in there. Hell, sell some of the **** you got sitting around your garage or house and raise some funds for the cam if need be.
I dont mean to push you towards doing a cam. I understand money isnt flowing like water for everyone, and its easy to say "yeah go do it". However, with the big money and big performance parts you are putting on (afr heads and a fast), a mean cam will make a night and day difference.
Either way, best of luck to you. I wish you the best.

I've got one, I want to wait and make sure the 92 intake I have on it isn't cracked, (i'm gonna have speed inc. check it when they do the heads) before I sell my LS6. I didn't torque it down when I installed it! Stop by anyway, you still got my #?

Now you guys have got me thinking about installing the S16 cam with my heads. I could sell my current cam for $200 or so, sell my LS6 intake for $300 and get some money back. By adding the S16 cam, i'm looking at around another grand including install. I'm thinking i'll get around 50 RWHP (with heads & cam) with the excellent tuning Speed inc. is known for. What do you think?

thats a large cam. About the same as mine now. I love my cam. It isnt tame, however. I get a lil bucking if i have the rpm's to low. Just be aware. What are your goals? Do you want a top end screamer? Or do you want alot of off idle *****?
