man have i been asleep or something to miss all this fun?
I've got a lot going on but will say that there was a dyno pull after that one that did make 504rwhp. The stuff works.
Thanks for all the compliments. Car does have quite a history.
The only detail i will leave you is this setup ran 11.17 with some real issues. That is what i'm working on now.

I think there is a lot of potential in these heads, or anything 21* for that matter, I wonder what an all out LT1 with these and a good matching solid roller and single plane would do???

That car has always been a favourite of mine if its the same car im thinking of which is a 93 Yellow Formula? Ran 10.98 if not faster iirc when he made the compilation he made on youtube. I guess we'll be seeing some more results from him this year when he goes to the track with it!
But...couldn't have lost to a better guy! And Phil if you're reading this...Frank is the reason i dumped my life's savings at Advanced Induction in 2011!!! Thank him.
thanks for the reminder LOL
Bullets fit way better, but single chambers just sound w/ the true duals and X or H. You can hear it good in those vids.
Drivability is no problem...but i'm used to driving a big cam M6. You can't let off the clutch and expect it to cruise at 3mph, but you can certiainly roll and let it idle through a parking lot. I think the tune has a lot to do with it. With the old motor i drove it daily for a while between dedicated daily drivers and that cam was no less likely to jump than the new one.

there a little small for a big inch combo. 21* is good but a 18* or less would be the way go for a all out race combination.

True, but I was thinking of a lt1 spesific head, the best I have seen is 21*, I agree though if I was going through the effort to convert headds it would not be anything more than 18*, but I am personally thinking of staying with an LT spesific casting...

run against you mentally screwed me way up. All day i had been limping that blown clutch and had a rythm down...in the right lane. Well...line up against the bada$$ Ai equipped Impy and despite supposed lane choice they stuck me in the left lane for the first time ALL day. On the vid you can see i all but snored at the line.

Alan, Don't get down on yourself for that one mistake because you can drive the hell out of that six speed. I was proud to get the opportunity to race you.
This is one of my favorite pics of your car.

The 21* TFS are badass heads still, and seemed to work more then good enough on this medium cammed 6500rpm 396, but just don't have the size to feed a max effort high rpm stroker.
For me, a "max effort" NA LT1 build would be a 13:1 SB2.2 headed 410 with a Dominator flange Supervic and nasty 27x/28x solid roller with over .700 lift. You know, a street car .
...I promise I'll make one when I win the lotto .

Afr 227 is the biggest head that's ltx specific and its even a little small for a max effort stroker.

IIRC AI said they don't have the porting potential of their traditional TFS packages, so they still recommend the 23* TFS package for their serious stroker setups. As far as gen2 specific heads go, AI TFS heads or ported AFRs would probably be the go-to castings for most...although there are some nice CNC'd Dart heads floating around, and Brodix will convert any head they make into reverse cooled for you from the factory for $400.

I saw that someone else posted up that Jeff Creech at CAM has tuned it for almost 10 years now. I will leak a little something here...probably going away from the LT1 pcm if all goes well.
Oh yeah i remember. Hope your car is doing well. Those telstars are famous...i bought them from Shon Herron who used them on the bolt-on record holding silver camaro he had for years before doing an lsx swap.
