SPRAYED Z

I have a 388 lt1 forged bottom end and using a flat top forged piston built for nitrous. Im also using AFR 210 heads that were also max ported. Lt4 intake and LT headers, bullet, dump. Backed by a th400 trans and a 4.10 gear on 28s.
I will be using a 250 shot minimum and would like to know what the hardcore guys recommend for this setup!

What converter should be used?
What cam specs if any? I would like to be HR still
What size throttle body?
anyone with a similar setup to this?

This will be on a stock pcm and im looking to take it all the way to 7000 rpm. SO I need my parts to match, thanks guys

NO help from the bigshots? or is because I have a LT1?

have you posted this in the LT1 section? may get more responses in there.
you could even try camaroz28.com i got alot of LT1 info from there.

your torque converter is going to depend on the cam and where your powerband is at.
as for throttle body, i say the bigger the better but most likely your restiction will be the intake.

Really I see most guys still running a lt1 intake that is ported and easily going to 7k rpms.

I posted in the lt1 section too

are you going to tap the intake for nozzles or what? 250 isn't going to fly through a plate that well.....

I can flow 400 through my plate from N20 outlet with hardlines. There are ways to get that done. I am running around 250 on my setup.




As far as cams and stuff you need to contact Elliott portworks and he'll take care of ya...I would also recommend a converted single plane with your setup...stock intake will be your downfall, but is budget friendly.

Like others have said coverter will be dependant on hp/tq curves. I run aYank SS 3800 in my car.

Well I used to have a Forged 383 LT1 and eventually was going to go Nitrous. Just could never get a 4L60e to hold together and 4L80e's were not as prevalent and then TH350/400 was not optimal for the amount of Street Miles the car gets.

BUT all that aside to answer the question as in if I was doing this would be....

Converter- Set up with Nitrous in mind. Pick a good company like Circle D, Yank, or even Protorque. RPM would be based on their recommondation but I think it would certainly be tightend up a little bit.

Cam- As much as the motor allows for, probably more exhaust duration then normal, again would be a question for a cam company or a Guru like Lloyd E.

TB- You can stay stock sized or even go Mono Blade. The intakes though starve the front 2 cyl anyways so your looking beyond a plate kit. You really need a Direct Port for 250 shot. Dont even mess around.

MANY people spray more than a 200 shot with a plate kit
