All lt1s in vettes are 4 bolt, and some 97's got left overs with 4 bolt mains.

I will talk cars all day long, doesn't matter what kind it is :)

I and he work on both, that's why I lumped them together.

You mean LT-1 ;) I will take getting 30 mpg to the track and running faster times than the old LT-1

Not all are 2 bolt mains, some...

It has an after market adjustable wastegate, the vacuum line goes directly to the waste gate actuator on the fender wall. I was under the impression that the computer was controlling the boost. The...

Alright, update time. Pulled the plugs, they looked good,fuel 45psi at idle with vacuum line still plugged in, his MODIS read ~11 for a/f ratio at wot. Vacuum was around 15-16 at idle.

checked all...

Sounds good man, I appreciate it.

Lol, I don't know the guy, and it isn't even my car. My buddy is not an internet guy, which makes it even tougher. My realm of knowledge is pretty limited to SBC's specifically LT1s and I try to help...

There is no boost controller. It is a wastegate with an air line on it, specifically the one from fwd motion. In 2nd or 3rd it will never go above 10 psi, maybe 8.

He does have an adjustable fuel...

I fully get where you are coming from. I know he has an a/f gauge, and I know it is not the same as a wide band. It is running a tad rich, and I think he had it mail order tuned tune it slightly rich...

Found out some more info. It has an adjustable waste gate. Ignition timing is at 12 degrees. Cam timing was set when he got the motor from fwdmotion.

Here is a video. I was wrong, the blow off valve is not staying open.

you can see it kisses 16 psi, and then never reaches it again. 60-75 is really bad.

HkS I believe. I will have him pull the plugs. Him and I are both SBC/v8 guys, this is new territory for us, lol.

Is that the guy at the track I see all the time with the ridiculous Laser?

See, he has people said they are too little and too much. He did what he was recommended by fwdmotion, and the computer is tuned for the set up he has.

I could be...

Thanks guys. I convinced him to get it out of storage tonight. We will give it a try, and I will upload videos if we can't figure it out.

Since it's topping out at 16 psi, do you think it is venting into the atmosphere at some point? He knows that the intake, exhaust manifold and probably an upgrade fuel rail are ideal, but he didn't...

To make sure they are not leaking? Can this be done in neutral? I will take a video. I'm trying to convince him to take it out of storage

Where can I find a 2 piece intake and how much are they usually? Would It need to be ported to accommodate the 52mm tb? That should be pretty straight foreward.

how do you get a blow off valve to...

He does have a snap on MODIS, I'm not sure if that would be able to give him (or you) any answers?

It does not. Maybe I can give halves on one with him because I want it for my car.

I'm trying to help my buddy figure out his car. He has a 1989 shelby Daytona. It has a 2.2l enforcer II long block with the stage II head, 475 cam, 53 lb injectors, walbro 255 pump. The turbo is a...

How much?
