LT1 Tune

[Phantom409]

Well if you still have the # of the guy you got it from see if he can tell you what cam he put in it.
If I had to bet it's probibly a Comp Cam, it's the most common.

The way I told you to go about the tune cost a little but in the end you will be confident that it's right and not leaning out on the top end or on the bottom end.

The way Joel told you would get you close but to be able to tune it right and get the best performance IMO is to know just what you are dealing with.

Sorry Kyle but I will have to disagree with you. I have tuned several cars without knowing cam specs. You simply give the car what it needs via wideband, that's all. The only time you need cam specs is if you are wasting money on a mail order tune.

I have tried to figure out what cam it has but I cannot get answers so I have given up on that.

I'm not sure I have what it takes to tune it, I would need to do alot of research...

[Phantom409]

Well James that's cool

I've tried the wideband thing and it didn't work, I fouled out 7 sets of plugs.

I paid 50.00 for a BIN file and with a little tweeking I was on the road and put down almost 400RWHP (shy by 20) and I think with a dyno and a little more tweeking I should be able to get real close.

The problem with mine was that the Fast & Slow O2's and the timing table, that was way off as well as the injector constant.

With out the stuff to burn and play with my chip I would have been lost.

From what I have been told with the stock computer is that anything with more than a .500 lift will mess up the computer and the timing.
I have found that to be true and that's why I point people in the direction I do.

My cam is 226/234 dur @ .050 .556/.568 for Lift & 108 LSA
It's not the biggiest you can get but with my combo it works well

Adam, ther are several ways and I'm sure that some one will be able to help you out.

A good site for info is http://www.CZ28.com
Look in there coputer tunnig section, it's loaded with tons of help topics.

Thanks for the help, I don't have any money right now anyways but hope to have it tuned before next season. I will do some more research

hey man id like more info on that cam. ive been looking at the comp 224/230 on a 110, and the AI 224/234 on a 110, but ive never seen cam specs like yours before im intrigued - and i like tight lsa ratios. who makes the cam and do you have any videos? how worked are your heads if at all? think it would work well on a stock cube and heads motor?

[Phantom409]

Well Joel this is a custom grind by Lazer Cams & they are no longer around
His website quit working and his phone is MIA

The guy was way cool too, he new his stuff and my car performs just like he said it would.

My heads are AFR 195's with a port match and I'm running 42lb SVO's to help my 383 put down the pwr. along with a 52mm TB and I'm running a MSD 6AL with NGK plugs.

You might want to look at the GM 847 if you are loking for a cam.

There is a guy on there called Chedder (Will) and he had a 94Z with this cam, 9" rear & N2o and was running 10's.
That was on a 383 Stroker also.

i think that cam might be a little big for me but ill check it out. I want to avoid anything higher than 6200 rpm, and ive read the 847 likes seeing the limit of the tachometer

306 is always a winner too

i want one that still has torque. ive read too many people complaining about that cam being dead under 3k. ...not the cam for me.
