lt1 dyno tune

[z28rob18]

ok starting a project soon so ive been pricing everything out and one thing i havent yet is a dyno tune. i need some reccomendations and prices. were building a 383 with a 200 shot and maybe a fab 9" b4 the tune. were lookin for about 450whp on motor and about 650whp on the spray. if u know of any shops or are a shop in the jersey area let me know. we will be using the stock 95 computer and if you'd lik more info let me know.

450rwhp with a 383? Better have some sweet ass heads, and a rock solid valvetrain.

[z28rob18]

450whp outta a 383 shouldnt be that hard a set of le2 heads and a custom cam 234/242 .612/.612 should get it there he rates the le2 heads at 410+hp and thats on a 350 the extra cubes will give it the extra power. so we should be close

[LTb1ow]

The extra cubes will boost your torque curve but you really should get the LE3s.

[NJSPEEDER]

I agree with ShowNoMercy about the heads. When people talk about the HP that heads are capable of, they are talking about max air flow. Cubes can't trick that, maybe you can grab a few more ponies, but max air flow is the same no matter what engine you through them on unless you go boosted and start jamming air into them.

Were are you getting the cam cut? Before I do a custom cam I usually call comp, crane, lunati, and a few shops to get ideas for specs. Just see what they are all thinking for the RPM range and power you want to run.

[z28rob18]

lloyd is probably who will cut the cam and the specs i posted r the specs he thinks will be used. and id love to go le3 but its kind of a budget and he reccomends starting with a set of after market heads. but i u guys hav any better ideas for the same price id love to here them i want to be at about that 450hp point.

T4Ps.

Its possible. A lot of work and money is a 100% def.

[z28rob18]

those r some good #s thats wat im lookin for pretty much the same as i want to do except 11:8.1 compression and i have 1 3/4" midtubes.

Another setup, Bret is a good guy, I am not sure whether people on here feel that way, but send him an email @ Bauer engines.

[LTb1ow]

Another one,

Again, lots of time, patience and money. But completely doable.

[z28rob18]

ok so wat r these t4p heads? who makes them and where do i find them. and brett is? u hav got me real interested in this

[LTb1ow]

Bret Bauer, engine/cam guy from NY. He used to spec all the cams for Lloyd but he switched cam suppliers.

[z28rob18]

so ur sayin to email him to grind me a cam and use the le2 heads that i planned?

[LTb1ow]

You could, but I would see what he can offer. The T4P heads shown above were from him, so you really need to talk to some suppliers and porters and see what you have the money for.

[z28rob18]

alright thanx for this ill email him and get some info

[LTb1ow]

And also, you need to figure out what you are gonna use the car for, making 450 at 7k won't do you much if you plan on streeting it.

[Pampered-Z]

450 HP on a streetable 383 is not going to be a problem. Lingenfelter's 383 made 420HP, 50 state legal with the little 211/219 cam.

Just remember you want a cam that is going to make the power in the 6500-6800 RPM range. You don't want to try spinning to or over 7K with a stock EMC and opti.

Depending on your budget, I good set of ported LT1 heads will work fine, LT4 would be better, and aftermarket even better. Trickflow just announced a 21 degree LT1 head that is suppose to have some big flow numbers? I haven't seen any real data on them though. I'd love to try a set out on my setup!

My own opinion is to just not go cheap on the valve train, spend the few extra dollars when you get the heads and go with, double springs, upgrade lifters, hardened pushrods, guide plates. With high compression and nitris you really want to control the valve train, and it sounds like you are going to be running a fairly aggressive cam for that much nitris.

What the heads will support is going to effect cam selection, but in general, ... If you want the car streetable, be careful with your cam selection, the stock ECM can only be tweaked so far before the cam surge will prevent the car from idling and having any street manners. You're probably going to want a cam in the 236-242 duration with a tighter LSA to bleed off some of the compression since you're planning a 200 shot and still make power in the target RPM. Some of the big nitris cams really need an after market EMC and ign. system.

thanks for all the info guys the car will be and is my DD but it gets track duties as much as i can go. the cam that i listed was wat lloyd elliot said he would most likly grind for this i told him its my DD and he said opperatng range is lik 2200-6400rpm range and im looking into heads now and wat i can do. because 450rwhp is wat we want if not more.

[LTb1ow]

I see you joined ls1lt1

[z28rob18]

yea i did lol tryin to get intouch wit that bret bauer lol but i looked in that one section real quick and decided to post on that one guys question lol i might be on there a bit but i usually stay n ls1tech check here and its been awhile but i also am on camaroforums but i dont go on there much cuz its mostly stupid stuff bein talked about. do u know anything about the lingenfelter heads the ones that r lik 1400 they dont give details

[LTb1ow]

Never really researched Lingenfelter stuff.

[z28rob18]

so say i do hit my goal of about 650rwhp on spray wat kinda times should i be running if i get it to hook?

[LTb1ow]

11s. Until you break anything stock left on it.

[z28rob18]

wont be much stock buyin a new rear wit 4:10s and a new driveshaft with a torque arm and sway bar
