OK I have got just about everything I need for the new motor. I got the 383 short block together(10.5:1comp) . AFR190 heads, miniram, 58mm TB, 30lb SVO injectors, t56 tranny out of a 96 camaro waiting for me back in the states, NX wet kit(adj 50-175)

I am still in Germany but I will be back home in a couple months and I want everything to be waiting for me so I can lock my self in the garage with a couple cases of Corona and get to work....
I have done a gazillion searches and I have it down to two cams.

1-xe230/236
2-xe236/242

I have noticed alot of people using the 230/236 and they say they love it but they always know someone with the 236/242 and say that it would kick *** in a 383. I have surfed around at camaroz28.com and searched what the lt1 guys are using and I get the same response from them... I will be using either 3.73 or 4.10 gears depending on what cam i get. Also I would like to use 1.6rr's to get more lift(the springs are good to go)

I want this to be a strong NA engine and just use the bottle for that biggerfish at the track.....

So as of right now I have everything but the valvetrain and its time to get it.

Is the xe236/242 a little to much for her or just right? Any body allready been down this path and could help me out I would appreciate it.

And yes I know I will need alot of prom tuning but I have been screwing around with that the past six months or so.

sounds like it's going to be a monster..... i'm building the exact setup but stealthed for mine......

the xe282hr cam is perfect for your setup...... enough power to throw the rearend to a thousand peices and calm enough to be streeteble......

**warning* though, this cam hit my rods bad....... the lobes are practically square and stroker clearence unless a good rod is used will be a problem.......

your combo should thump out 500hp at the flywheel with around 492ftlbs.........

everthing that iv'e seen in books that use that cam produced around 490hp and well over 500ftlb or torque.....

i had to send mine back for a small base circle grind and right now their out of cores... they should be in soon hopefully and i can have my beast running as well.......

by chance how much block clearence did you go with???

everbody i know and called said .050 is good how much do you have??

let us know and i can't wait to see a video or hear a sound clip of that.....

rocc4u

I had the short block put together at strokermotor in the Dallas area.
I talked to Nu-tek about these cams and they can have them in a small base circle, that is really what you need to make sure of.

I have read a few of your post and I think once you get a grind with a smaller base you will be fine with your set up.

If you wanna acheck out the site go to www.strokermotor.com

I am in a very very very similar situation. I have the same trans, heads, basically same manifold, 406, etc. I have nitrous too but see that as backup. See sig.

I need a valve train also. I have called Comp cams, Crane cams, TPIS, LT1 motorsports, posted on LS1.com, lt1forum, TGO, corvette forum, and emailed many many people that have done this or similar before me. I feel that our engines are on the border between a solid and a hydraulic roller cam. If you have a roller block, your choice is easier. But if you are me or others that need retrofits anyway solid may be better.

Give me a rundown of what you want out of the car. Quarter mile, idle, engine internals, exhaust. From what I have seen, I am going a single pattern cam. I see AFR cars run very well with single patterns. Like the magic 219 219 cam, or the ZZX or the becoming popular 242 242 solid TPIS sells. The exhaust port of an afr head is very strong and IMO, a dual pattern is not needed. But, those comp cams are cheap!

Lethalracer has that cam in a 383 in a 91 Z, and went 12.40's @ 116 on street tires. Get it.

rocc4u

88gta383-What cam are you refering to?

I took a look at the combos that are posted on www.afr.com
They have a few 383 set ups and there is two that damn near the same except for the cam.

The first combo uses the xe230/236 and produced 480 hp and the second used the xe236/242 and produced 500hp(20hp increase)
I know these are on carbed engines but it is still a good comparison. From what I have read the 230/236 is perfect for a 350 and the 236/242 would be just the same for a 383. The only thing I would like to know is how streetable it would be. I dont want to be sitting at a red light reving to 1800 to keep her running.
As far as the exhaust will go I am still a little undecided. I am leaning towards the 1 3/4 SLP but I may go with the Hooker SC.

Thanks, Rocc

Rocc4U - I had the exact combination that you are building. My cam was a custom Comp XE 230/236 .544/.555 with 1.6rr and ground on a 112 lsa 4 degs advance.

We tuned the motor on a Dynojet and made 385hp at 6450 rpm. The torque came in at 419 @ 4400 rpm. The torque number is a little scewed due to the torque converter flash.

Two recommendations for you:
1. Install Comp 987-16 springs on the heads. The AFR springs are mediocre at best.
2. While putting on new springs, install Titanium retainers. These light weight retainers are good for a few hundred more rpm.

I ran the car after tuning on the Dynojet. It went 11.81@115 with street tires and full exhaust including cats. Further tweaking resulted in consistent et's of 11.70 at 116.5 again with the same tires and exhaust.

I have since gone to a solid roller 248/248 .614/.614 112 lsa, ported the AFR's, 36# injectors , 3" y-pipe, no cats and a 4" Mufflex system. I haven't made it to the track yet but am expecting 11.50's.

236-242 He's getting around 8-10 inches of vacuum and it idles at 900 rpms.

rocc4u

So your telling me that I paid an extra 175.00 to upgrade my springs and valves for pretty much midiocre.....I have never heard anything bad about the AFR springs.
I however did not get titanium guides but I think I might install them before its all over.

So what I am hearing from you guys is go for the 236/242. Thats what I wanted to hear. I am someone that believes in "Go big or Go home". But just to be safe I wanted to make sure before I kicked myself in the A$$.

It will still be a couple months before I get to Texas and start putting it all together, That is if I dont end up in a big sand box over in Iraq first.

iTrader: (4)

thats why i went with the 282hr cam.....

it has a little more vaccum and enough to have a shred of power brakes.....

if ya need a small base circle grind, i can give ya the part number for mine... it's nothing but the 282hr with 112* lsa for streetability... according to comp with 112 i won't lose any hp or torque...... iv'e included a link to a sound clip of that cam, remember it's open headers so don't let it scare ya into thinking too much overlap!! lol...........

Yeah if you could throw that part number at me I would appreciate it.

Oh yeah and that thing sounds bad ***. Good job.

thats not my car......... i wish it was........ that came from a dude at another fbody board.......

i'll yell at comp and get that part no

heres ya go.....

good luck and i hope it's as good as ya want!!!

rocc4u

I will give them a call. I just dont want to get the 230/236 and in a couple months wishing I would have gone just a little bigger.

I am also trying to keep it a little streetable also..

LETHALRACER

I am the guy 89gta383 was refering to. I have the 236/242 in my car and it runs fine. I have 10.5"hg at 800rpm idle. I have bigger heads but I can spin a lot of tire at a 45 punch. I think my moter will go 119 with some traction. Go with the 3316/3317 and use 1.6 rockers. You will be much happier. I run a vacuum resivior just to be safe. The idle is a little choppy but it sounds wicked. By the way I am personally switching to the ZZX cam from TPIS. Check your INT/EXH flow ratio. Over 80% is single cam territory. I forgot the cam is on a 112lsa with +4 deg advance.

rocc4u

So You think Get a grind like badgta says

part 08-000-8
grind cs3315s-3316shr112+4

but get it 3316s-3317s ???

How is your car when your just driving around and not getting on it? You wouldnt happen to have a video or sound clip would ya?

LETHALRACER

I know for a fact that the 242 side of the cam is the 3317. I am not sure about the intake. The car drives every day just fine. I would get the cam I have in my sig. I drove it to NC from TN and got 24mpg average. I also have a 4,000 Vigilante and that makes it hard to tell if there are any problems on the low end. But all types of cruising only take about 12% throttle. I get no bogs or lack of pull. The only thing I did do was increase my low speed lock up to 42mph insead of 35. Actually I did have a stock converter for a while and it ran fine like that to. The power came on later but there was still enough low end to do what ever I wanted the car to do. All I have is VHS of the car. Sorry. Good luck with what ever you choose.

rocc4u

I am about 95% sure that will be the cam in my plan. I would just like to hear it so I can get a chubby over how mean it sounds. I have heard a couple 230/236 set ups...Thanks alot. I am gonna drink one for ya....

LETHALRACER

Maby a dumb question but are you in the Army? I am a Staff Sergeant at Ft. Bragg with the 82 ABN.

rocc4u

Was it the beer or the Cowboy Jersey that gave me away?? I am stationed here in Katterbach, Germany. I came from the 101st and I will be at Ft Hood in a couple of months. The Army calls me a Aircraft Mechanic but you know how that goes....You do what needs to be done and if you get time you do your job.
How long you been at Bragg???

LETHALRACER

I spent my first four years at Campbell. I was in the 3/502nd Scout platoon. I can't wait to go back there. I have been at Bragg for about seven months. This place sucks. I am here waiting to start the SF Q course in March. I think it was the Germany thing that got my attention. I will sellect 5th SF group when I have compleated the course. I liked Tennessee. I assume you worked over in Avaition. I drove a red 91. When did you leave there. I am on Staff Duty right now.

Hey, good you guys have stuff in common. Lets leave that to the PMs.

LETHALRACER

Thanks for the tip. I will remember that next time.

rocc4u

I was there from 97 to 00. I have a couple friends that should be on their way over there for assesment pretty soon. Good luck with SF.
Also thanks alot for the info on the cam.
You got any pics of your car?
Take it easy, Rocc

LETHALRACER

I had some good picks but I don't know what happend to them in the move.

IrocStan

Would you guys have the same recomendations when using an Lt1 intake rather than the Miniram?

Austin

rocc4u

Yup , It would be pretty much the same. They are Basically the same thing. It still depends on where you want to make your power at though.
rocc

Matt87GTA

At the F ease.....

63W20/92A20 here.

LETHALRACER

A friend of mine uses the LT1 intake and I am not sure he is happy with it. Actualy he is in the process of looking for a Miniram. The Miniram uses a three in runner. It is not big on the torque figures so you might as will use the bigger cam and shoot for hp. I am not sure how long the LT1 runner is. If I could do it all over again I would adapt a Victor Jr. manifold and a 1200cfm throttle body.

rocc4u

Couldnt have said it better myself MAtt.......Any of you guys going to the big sandbox soon. I think I am

LETHALRACER

I was schedualed to but the Q course got in the way of that. I am sure after that I will though. I am glad it got put off for a while. My wife and I found out yesterday that she is pregnant.

GofasterFirebird

I was under the impression that the mini ram was designed after the LT1 intake. Speaking chronologically and in design.

Matt87GTA

Myron will tell you differently.

No word on me (us) going at this point, but the directives to change the training plan to include more and more NBC training just keep rollin in......

Congrats Lethal!

What does Mryon say?

LETHALRACER

Thanks Matt. We have been trying for two years. All I can say isw that *** blessed us at the perfect moment. You never know what is in store for you.

Matt87GTA

Well I really can't speak for Myron or TPIS........ But basically the Miniram came to market before the LT1 intake found its way onto the LT1 engine.....

Call TPIS and ask them for yourself:

952-448-6021

Don't bother Emailing them, they likely won't respond to it.... Myron despises all of the "Internet Experts" out there that claim this and that and rarely responds to that type of question via Email....... Actually they rarely respond to it at all, but you can give it a try.

GofasterFirebird

iTrader: (3)

GM copied TPIS? TPIS claims that the mini was out in 1991. I would assume that the LT1 was designed too. Who knows

rocc4u

Does Anybody have a video or a sound clip of a car with the 23/242 in it????

I am still beating my head on walls to decide on what cam I want.

Brad

I have no sound clip and no FIRST HAND experience since I am still installing my engine, but just go with the 236/242. I had Nu-tek Motorsports build my 396 and I told Nick pretty much the same things that you have mentioned. I don't mind some tuning, but I wanted a streetable cam because I end up stuck in traffic sometimes. He personally picked out the grind for me which was 236/242 112 .555 int / .576 exh (with 1.6 rockers). I realize I have a few more cubes than you, but I still think that your 383 would be fine with that cam.

rocc4u

Thats what I am really leaning towards but just like you I dont want to have it stalling out on me or suckin *** in traffic because I will be driving it all the time.
