AI 200cc CNC heads, Guess my hp
I just got my AI 200cc CNC ported heads bolted on & can’t wait to get everything going and tweaked on. They look sick, like the pics they put on their site of the 190’s with all the flanges cut. They also machined everything so it fit together without having to grind on bolt holes.

All I care about is what it runs, but everyone wants to “race” the flow bench so lets get that out of the way first.….
Lift Intake Exhaust (no pipes)
.100 72.1 60.4
.200 148 116
.300 205 153
.400 247 173
.500 275 188
.600 284 194
.700 285 197
I know they all pretty much look the same these days. Ai says the actual flow numbers don’t mean much & that there are different ways to get the same flow or dyno number, but one of those ways will perform better than the others. We’re gonna find out soon.
Obviously the heads alone are just a part of the story. Here is the low down on the rest of the car:
355 cid LT1 block with a stock crank, Manly sportsman rods, 4.030” Mahle Powerpack’s, Main & head studs, double roller chain W/ e-water pump, solid roller, comp pro mag 1.6 rockers, AI ported “street/strip” LT-1 intake, AS&M 58mm TB, hooker 1 ¾ long tubes, slp 2OTL, 42 lb SVO’s. I’ve got a m6, 4.56’s in a moser 12bolt.
The car is full weight with all existing factory options & systems present and accounted for, and a nice PG amp and complimenting speakers. Ok, maby not all of them ( !EGR, !CAT ECT…)
I had wanted a hot 355 for street duties that I’ll drag race a few times a year. I wanted 440+ rwhp and at least 120mph traps. I wasn’t sure about the solid, but after my experience with the comp-r’s
I told Phil I wanted to try the morel hydraulics with the new head and cam. He suggested a mild SR to eliminate the hassle of a HR. He also pointed out that the added spring pressure would serve as ‘insurance’ since I mayyyy, COUGH #! miss a COUGH gear at some point COHGH/ HACK, over rev the engine. Not to worry though I am confident in my ‘mad rowing skillz’ 
. Sorry guys, no specs on this cam, but it ‘s about 10deg smaller than the usual suspect cams that go in most of the faster solid 355’s, and the same .050” duration I see 355/383 HR guys run. I am told It’s not as aggressive as the XE lobes people run and is like 8X something degrees to 200 something or another. In short, they say it’ll drive like a smaller cam, I guess we’ll see.
I have a mail-order tune from CAM, and will get on the dyno as soon I can. I just want it to run hard when we take it to the track afterwards, but dyno days are always cool. My old Ai topend with a HR went high 11’s so hopefully it’ll be faster this time!
So what do you guys think?

.2 143/110
.3 198/143
.4 243/171
.5 274/184
.6 284/196
.650 287/201
We're running the same engine set up Let me know what numbers and ET's you get. BTW those heads look sweet. I'd say Low 11's high 10's with you're set up.

Re: AI 200cc CNC heads, Guess my hp
What was under your $1000 valve covers that ran 10's if your Ai package went high 11's? Good luck with your 120+ if you're running as small of cam as you're trying to make it sound. Holly crap 4.56 gear whats that like on the highway? I'll bet you're a second and 100 hp off of Ricks car

FASTFATBOY- The car weighs about 3700 w/me in it.
96 Flame- Thanks for chiming in. Your expert opinion is always highly valued and will be taken into consideration. It would be a major accomplishment to be within 1 sec of rick's car.... which kinda puts me 1 sec ahead of your car
. I just don't think I can beat a drag car like that with a 100% 6-speed street/ weekend racer w/AC, that I bought a set of slicks for. Maby you can give me some pointers on tuning and setup and we can get there together. The 10 sec pass with my old setup was on the bottle.
Check it out. http://videos.streetfire.net/search/...84ce212c53.htm
Do you have any videos or slips of your 3800# car running what you claim ("if you're running as small of cam as you're trying to make it sound.")? Serriously, your e-check cammed car is faster than most of your LE buddies that have more aggressive stuff. If so, it would (at the least) be nice to see the evidence of your results, as I am going to (and have in the past) document my progress.
4:56 gears are sweeeet. Even on the high way. You can find out for your self if you have $200 for a ring and pinion, or you can just keep on posting what you 'heard' and not what you did.
Also the $1000 valve cover thing is a joke, I guess it's a sad state of affairs when even that needs to be explained.
Enough of this troll correcting, it's tiresome and boaring.

Re: AI 200cc CNC heads, Guess my hp
are you still working on the suspension? i take it your car started at the 14 slip and is at the 12.15 now. its weird years ago and i mean years, 2 guys i know in the carolina f-body club was running 12.2's with a LT1 with only cam, headers, 12 bolt with 4:10's and a tune , CAI as well. as a great movie once said (with a twist) "A car is like a box of chocolates, you never know what you gonna get". hope you get the et to match the mph. as far as respect goes in my eyes people have to earn mine , it is never given easily. hopefully when i finish mine (maybe spring, depends if i go to scotland for vac or not) i am hoping for low 11's motor mid 10's bottle with first stage. like i said though , you never know what you gonna get lol. good luck to all and enjoy this expensive hobby.

Re: AI 200cc CNC heads, Guess my hp
Anything less than 475rwhp would be a dissapointment I would think. Since you seemed to be on AI's wagon and bashing LE stuff in the other post, I'll throw in my 2 cents.
These 200cc heads that Rick has laid down over 500rwhp thru an auto with a larger solid roller than you claim to be getting. I would think Rick's car would have laid down 550rwhp with a manual tranny... so you having a smaller cam and the same heads and a little smaller cubes... anything less than 475rwhp with your M6 will shed some light on these "AI200cc" heads. These heads sound like they perform, no doubting that. Its just funny how everyone that has AI stuff uses ricks car as a gauge... instead of their own, so use yours against Rick's.
Post results when ya get them... even if they arent what you expect.
