John i just wanna let you know you are the MAN!!! i got a manifold, fuel rail, and injectors for $125!!! from a 93 LT1.... ive started to read up like crazy on prom burning so it will run GREAT! What do you guys think of this LT1 Manifold stuff??? Also, John what kind of intake did you have before you switched (ported stock, big mouth, SLP runners ported plenum??? what??)

 

I was running a stock ported TPI ntake before the swap.

That '93 LT1 you picked up doesn't have the fuel crossover in the front like the 94-97 do. It's in the rear with the FPR. Might be a little tighter fit around the distributor.

All in all great price. When you sending it to me for mod?

john im going to try doing the mods myself with some help by the guy thats swapping in the built 355 as we speak..... So you dont think the 93 lt1 manifold will work????? Also, is there anyway i could borrow that distributor template for a weekend in like im guessing it will be like 2 months before i need it????

 

I didn't say the 93 won't work, it just might be tight back there.

Borrow my template? No, I can't loose sight of it as I can't make another one without a standard intake like a LG4 or TPI. Maybe you should look into getting a junk LG4 intake to use to help locate the hole. It would be cheaper then having me do the whole thing.

 

John,

I've been reading the posts and watching your progress. I've checked your pages on the conversion, too. Nice work, man.

If I were you, I'd protect that template as well. You may be on to something big. If you can find a small job shop in your area with an NC mill and no work, you might be able to set them up with some work. One short program and your in business. Just indicate the intake into position and push the "start" button.

Of course, you would be their "field sales person" and get the appropriate percentage of the fees. They could even manufacture the billet spacer rings for the distributor, making for a rather complete operation. I would think you could be profitable milling the distributor hole, drilling and tapping the clamp bolt, and providing a spacer ring. What would that be worth, when you consider it costs $130.00 just to have eight cylinders bored to a standard oversize?

Would anyone here spend $100.00 to have their LT1 intake prepped for install on a "regular" SBC?

Yep, I would In fact, I already did. John is making mine, and he said it should be ready Monday, cant wait to wrap my grubby hands around that puppy! It'll be a while before I can use it, though. I'm pretty strapped for cash right now cause I am finally moving out of the house

 

Ohh my bad John i didnt know you only had one.... i thought you would have made 20 of them by now.... yeah i even have an extra bare TPI manifold i was going to port out... i just thought you might wanna hook a fellow thirdgenner out

 

It seems all the LT1 intakes are spoken for.

 

Thanks Vader for the good comments. I did the swap because it needed to be done. Part because my engine needed more air and part because I was tired of hearing people say it can't be done. ANYTHING can be done, it's just a matter of how involved it is. I don't believe it's that hard of a mod.
I was a machinest in my formor life and know a few things about machine work. Thats one of the reasons I did this. Also I don't want any localk shop getting involved, I don't need them. I am making a jig to do the bolt pattern exact every time with a basic hand drill. And my template, well I'll hang onto it.

 

dang $130 just to get it bored..its only about $64 a here. I would pay$100 to have the distributor hole lined up and bored and the spacer made.

 

My brother who was real big into camaros when I was a young one. He's had one for 14 years, thirdgens only. I showed him johns at the thirdgen gathering, and was like take a look at this.
He said, "what? It's an LT1 intake."
ME: Yes, on a first gen block...used to be a TPI engine.
HIM: So, they used to make conversion kits.

No clue if he's right. He said back when he was real big on moding his 91 (this was back in 93-95) he said a company made them.

Anyone ever heard of this company?

i got a question for the lt1 intake guru. i just bought a 93 intake as well, for 90 bucks. think id be able to mill the top of it for a front fuel rail crossover? or is there a serious lack of meat up there. i hav not picked up a set of rails yet. otherwise ill have to get trick with some AN fittings. also BIG QUESTION- i checked out how sbc gaskets look on it, what did you do if anything about the center egr ports on the heads? i think a set of gasket with plugs to block them off? of add some jb weld to the intake.

 

Does anyone know the N/A hp limitations of a stock LT1 manifold on a 383, it seems like most LT1 engines have ported manifolds and I just found this LT1 manifold made by edelbrock:
http://www.dougrippie.com/drm/induct...ponents.htm#C4 Performer LT1 Manifold
Anyone have flow #'s for the mini-ram, stock LT1, ported LT1, and this edelbrock one? It would be a shame to cut up a new $450 manifold, but it would still be cheaper than the mini-ram with possibly the same HP potential. Hopefully someone can catch on to the point I'm trying to get across.

 

John can i just sell my 93 fuel rail and get a 94+ fuel rail?????

 

No, the intakes are differand, you would have to machine a slot in the top front for the crossover and I'm not sure if there's enough metal there.

 

One more question john ill prolly send you the money to have my manifold done a few months down the road your still doing it for $100 right??? also heres my question what should i do abbout the prom with the lt1?????

 

I never mentioned a price. That was Vader, I have told people to e-mail me privately for a price on exactly what they need down from just the distributor hole to a complete kit including everything. Be aware, I am out of intakes though. I am currently searching for more. of course you could send one to me also.

Looks like I better get start on converting those LS1 intakes for our thridgens!

That templet is not that hard to make.... If i had a 327 or larger I would want the LT1 intake but it would be overkill for my 305 for which a hopped up stock intake ported and all will be fine. Now, if someone can mod the LT1 intake for vortec type heads......LT1 and Fastburns with a nice cam on a 383.....droooolllllllllll...humm what would that be like on a 327?

Thats what I thought when I first heard this. I've never seen one of those intakes off the car, but I am willing to bet it is next to impossible to just mod one of those and be able to put it on.

 

John what is everyone with maf gonna do with the prom??? it wont even run with the stock chip will it??

 

It'll probally run, but not great. You will need an aftermarket or custom prom. I would stay away from the basic aftermarket ones. They are for known basic combonations. How many LT1/L98's are out there? One.
I would think about burning your own are get a Ed Wright chip.

John i figure you know something about prom burning..... does the i posted a link for a stock LT1 Maf table on your other LT1 subjust could you program that onto a TPI prom???? is it any help.... dang im gonna have to get into prom burning!

 

I do burn my own proms. Speed Density only, I know nothing of the MAF tables.

 

Have you given any thought to the LT4 intake? I know a lot of the 4th gen guys put them on their LT1s. I'll shoot you an e-mail. I'm very interested in this conversion.

 

How well would the LT1 intake work on a 305??

John

 

A STOCK lt1 intake would work WAY better on a 305 than a STOCK TPI Intake.... thats for sure!

 

All I know is a LT4 intake won't bolt to LT1 heads. I have heard the ports are higher and the bolt pattern is maybe differant.
The 4th gen guys usually change both intake and heads. Where do you think all the spare LT1 intakes come from? Their certainly not converting to carb!

 

I don't have any idea. As far as I know no-one has tried and tested it. Wanna be first?
I was first with a 383.

 

John why is your car so slow for what you have????

 

You're right about the ports being higher. The bolt pattern is the same, though. Now that I think about it, it would be way too much trouble to make it work. There's only minor differences in the port height, but it's enough.

 

How much taller are the ports what abought the with that may be a good intake to try to adapt to the vortec heads.

 

What do you mean slow? I pulled a 13.44 at almost 105mph in SECOND GEAR!
My tranny was sick and i didn't get a 2-3 shift till 7200rpm, by that time i was cross the traps.

 

????????

 

Didn't make much sense to you either eh?

 

I think what Earl is saying is that both the LT4 and Vortec heads/manifolds have the raised intake ports on them, so they might match up pretty well compared to trying an LT4 manifold on an LT1 head or a Vortec manifold on a regular SBC head. Anybody up for a gasket comparison between the LT1, LT4, and Vortec manifolds?

If I get a chance this weekend I will see if I can find a set of lt4 gaskets I have a set of vortec already atozone will hopfully have a set in stock.

 

Is the Miniram Still better than this setup?

 

Maybe, maybe not. But it's 3 times more expensive...
