NEDyno can do it. Mike (kid with the caprice) said he is willing to help, but your car will need dyno time in order to do it. So, you may as well have NEDyno do it.

What kind of tuning?? i for somereason dont think you need your spark plugs changed:eh:

Is it and LT1? need a chip??if so what does the chip need to do?

He's building up an LT1. Going with a 391 stroked block and AFR heads. The stock tune will not even come close to running that motor. So, he is going to need some dyno time in order to get it running right. Probably going to need some new injectors (I know he will for a fact), maybe a larger fuel pump too.

if im right i beleive the stock injectors are 24lbs and theres no way they will feed this motor.

Well, maybe call hypertech, see if the programer can accomodate the needed adjustments, FWIW N/A is a waste of $$ in those cars there too heavy imo, i'd put a stock motor with boost and pop them like chicklets before i spend 4-6k on a 420rwhp car that may run hi 11's and run like a pro stocker

Well, the 391 stroker SHOULD put down about 450HP at the wheels, if not more. Thats not too bad. You're not going to make much more power then that off a stock LT1 block. If you want to make more power, you are going to need to spend big money on an aftermarket block. So, its not a bad route. he is getting the entire motor for $5000, which is a slammin deal. Either way, I have a buddy with the programming software (LT1-Edit and Tunercat). All we need is dyno time.

Your going to need LT1 tuning, 1994-2002 F-bodies need to get the PCM reprogrammed, only the 1993 uses a chip.

Who is building the motor? I hope someone that knows the LT1.

You can check out my Camaro SS and my 396 Stroker on my website.

www.96Z28SS.cz28.com

Don't assume that because its a 391 stroker your going to get 450rwhp. Cam selection is a big deal in the LT1's and they go from being streetable to not streetfriendly very quickly.

thats why hes looking for a good tuner.....he's buying the motor from speedomotive and they told him to find a good tuner to help him decide on the cam.

Nothing is ever their fault :song:

I would avoid Quest also. If you want an all out drag car then they can build you a motor. If you want a street car then they aren't the ones to build you a motor.

But I'd like to here his story cause I think i know the story but would like to here it from the owner.

I got a few stories same ones Marc does.

450hp at the wheels with a 391 is a long shot. With that kind of motor, if the setup and programmer are just right, those #s might be obtainable. Ive seen a tune done Via email, then the same car with a PCM/dyno tune in person with a wideband O2, net almost 50 more hp... So It could be done. its all in the cam and heads with LT1s..
I'm not waltzing in here claiming to be a know-it-all, but from what ive seen around these cars, and knowing the guys i do, to put 450 NA to the wheels, you need more displacement, and porting outside of AFR. AFR's (i dunno if your going with the 210cc's or bigger) but they are known to have great castings, but can be made much, much better with outside porting..

FWIW A guy I know has a 383 by raceprep, and custom tuning by a guy out in CA where he lives, and hes pushing around 390 at the wheels, but torque is in the mid 4's..
Fastest NA Impala/caprice I know of making that kind of hp is a 398 buit by norris racing, previously owned by Keith brantley in FL, running 11.50s... Granted thats with a pretty well setup and lightened imp, but still..
24lb injectors are ok to around 400hp NA, at 100% duty cycle (WOT) I would definitely upgrade to be safe (to keep the duty cycle from being in the 80-90 range around town), but also because I would go to an SVO injector, pushed to there duty cycle and failpoint, stock GMs lock shut, rather than open, and boom. :bash: Even a 24svo would be ok, but id go to a 30. But im not the tuner, he might say otherwise.

Ed wright is one of the best LT1 tuners, but you will pay dearly for him, (his tunes are like 2-400 bucks.
My buddy Karl has run 12.60s with his NA 350, with the same tiny a$$ cam I run (crane "227" 210-224@.050) and a set of Agostino sp? ported AFRs and mid 11s with his 383 combo in the same car on a Ed wright tune, .

I thought Id share my Info on LT1s since i have one.

My tune isnt even close to right, yet it still nets me 13s, but i know its not right. Its alright, since when the new alum heads and XE cam go in, its gonna need ALOT more tuning..:thumbsup:

400$ is a gift if the guys the best,tuners i know get $100/hr for DFI type systems

fwiw 96z28ss has more experience than any1 else on here in my opinion on this subject, i believe he has a pretty nice motor and his makes like 420/30 if i'm not mistaken, i can't see gettin much more than that out of 1 of those motors and i find his pretty impressive

If hes gettin that at the wheels, thats a damn stout motor, and yes its impressive :worship2:

I should restate my above post about Ed: He is the "best " with known "off the shelf" cams for " E-Mail programming" He obviously would have more trouble trying to send you a program over email if you have a custom grind or a not so normal setup. But, if hes in person for the dyno tune with the irregular setup, again, hes awesome. This guy Bill from Long island flew him up to LI to tune his new supercharged stroker combo.. (this car is also deep in the 11's) :hmm: So to be flown up to tune a car, hes gotta be doing somethin right!

My 396 LT4 motor put 434rwhp, that was only 10 minutes of chassis tuning, I ran into some ignition problems so I stopped.
I'm fixing my ignition problem right now. So i will hopefully have new numbers in the next few weeks.

Gm really screwed us on these motors, there like a SBC but then there not. The intakes on these cars are really holding us back from making good power. If you want to spend $2500 for a sheet metal intake be my guest, I know I'm not spending that.

I have spent more than $14k on my drivetrain.

If you want to make serious power for short money on a stock bottom end, trade the LT1 in for an LS1.

I think those intake cab be improved by cuttin the top off and effectivly gutting it then smoothing it out as best you can and then weld the top back on:eh:

Rob And that is the exact reason why I've been telling him to get in touch with you. I also think that's why he posted it here. Speedomotive refuses to build him a motor until he finds a good tuner and comes up with some other parts reccomendations before they start. They told him they want him to be happy with wht they send him. And he's not looking for 450 at the wheels, he does however want to see 500 at the flywheel. He was leaning towards AFR 190cc's?? Enough of my jacking his thread, I'll let him fill in the rest assuming he gets near a computer in the next day or two. Thought or opinions Rob??

Well 500fwhp=400rwhp with 20% drivetrain loss

I'mm pretty sure he'll need more than a 190 to make those #'s

Good Luck

You should pretty much listen to rob, he has the nicest lt1-lt4 396 stroker I have seen, and as for the 450rwhp....good luck but I wouldnt count on that, maybe 420. Nedyno will get it done right the first time.:smokin:

AFR 190's out of the box won't get him what he wants.
i would get the AFR Raised Runner 210 or 220's with the AFR port and polish and buy a LT4 intake and port that to match.

I went the wrong route on my motor I went with LT4 GM heads and intake for $1,300 then proceeded to spend $2000 in port & polish to get them to flow and have the proper velocity.

So learn from me and get a set of Good AFR heads.

Crank doesn't need to be a high end piece, just make sure its Forged and made for the LT1 one piece rear main seal.

Rods I would go with a 5.85 length so that the Wrist pin stays away from the rings.

Pistons get a good set of Forged JE or CP pistons.

Rings I went with a set of Total Seal Gapless rings.

Longer stroke you need a Canton Oil Pan, rods hit the stock pan.

Get an eletric waterpump no need for the engine to drive it, and for it to leak on the FUCKING opti-spark.

Throttle body 58mm is good enough, I went with the monoblade but its overkill and to get it to idle is a pain in the ass.
You may want to get a Holley 58mm throttle body with the NOS fittings built in, its a trick piece.

Compression Hmmm daily driver? no more than 11.0 The good thing is the LT1 is reversed cool so it can take the higher compression with no problems although I would do 10.5.

Headers got to get a set of Mid length or Long tube headers.
mufflex y-pipe and don't Fuck around and get a 4" mufflex.
The single 2.5" and 3" exhaust on these F-bodys just aren't enough. And a true dual set up on these cars make the car undriveable on certain roads.

What else?? ahh Just ask if you have a question.

That should make over 400rwhp

Actually I do know someone that can build a stong T56 the guys down in CT East Side Performance they take the internals and swap in Viper parts. They did a customer of ours T56 and he dumps the clutch at 5000rpm at the track with a slick and runs mid 10's and puts down over 575rwhp. And drives the car on the street. Id say it a strong tranny and clutch.

We work with them alot, Just tell him the guys at NEDYNO sent ya.
Ask for Ken or Guy They should be able to give ya an ball park figure on what it will cost.

I've seen them take alot of abuse without breaking.
Well $2,200 for a built tranny will be worth it cause replacing the t56 gets expensive lets say $600 for each tranny, that mean you bought 3.5 tranny.
I like to spend the money once then never have to worry about it again.

I can tell you right now that the LT1 is the inferior engine.

i put more than that to the wheels with a 355. with an "inferior" 1st gen SBC

I wouldnt doubt that for a second.
In my opinion I think its much easier to get over 400hp from a 1st gen, not even stroking it, over an LT1. My father has a motor on a stand in the garage that only has like 9:1 compression and still estimated by PK machine to be an "around 400hp" motor.. I have 10:25:1 compression with simular flowing heads and internals. But like I said above my tune is off and tuning is a huge part of big hp lost or gained.
Even with proper tuning, my motor is/will be a far cry from 400.
I agree with the dumb opticrap GM decided to put on the front of the motor. Considering the main killer of optis is operation above 7k rpm, few guys have converted to HEI setups, but its pretty costly just to rev that high, especially with a stroker.

the SBC ramjet is i great intake, you could just take that intake, and put all the EFI stuff on a normal small block, make more power, keep the EFI, only thing you need is a stand alone ignition setup, i hall efect or optical trigger can be sent to the fuel computer without much dificulty.

I should have stated "stock"... Too bad the ramjet won't fit on either the LT1 or LS1.

Another nice intake for cheap is that tunnel ram from weiand i think its like 3-400 but i dont know if its lt1 compatible and or would fit under the hood/windshield of the F body's

I don't want it for an f-body ;-)

with out doing any modifications to the intake. The only options you have are the stock intake or GMPP dual plane intake to convert it to a carb.
