Since I have to pull my intake manifold off again I am thinking of doing the LT1 intake conversion on my L98. I found one for sale that is already converted to work on the L98.


Has anyone else here done this?

Do I have to swap ECM?

I'm obviously going to do more research before I make a final decision.

Thanks,
Jeff

i had one on my camaro for a few years. they work great if done right.

He had the distributor hole built up and then machined so that it's a nice flat surface. Sounds like he did it right.

shouldn't there be a minor angle to the dist mount boss??? It has to do with the way the intake is cast or something.

You won't need to change the ECM, perhaps retune, yes, but not replace.

Jeff, I would be interested in the intake if you passed up on it.

you could get away with just swapping the intake. a retune would be ideal.

Normally yes but from what he told me he had material added and it machined at the angle so that angled spacers wouldn't be necessary.


I wonder if I could use the fuel rail covers with this swap. I know that I'd have to cut them to go around the distributor.

Jeff - I will let you know. He wants $430 with the AFPR, Injectors, Remote T-stat housing and fuel rails.

Ok, cool. That sounds like a fair deal. The AFPR is $100, the fuel rails ain't cheap, either.

What injectors?

yes you can use the rail covers. it just need the bolts.

That's a good price for a complete package.

Well, he sold it to someone else.

lesson learned... snooze = looze... Sad...

You can do the conversion yourself, used LT1 intakes are not that expensive.

@Jeff - FYI - I was just at my local U-Pick-It lot. There is a 1993 Camaro Z28 in there, with the manifold. I can get the manifold, with rails (and injectors for what those POS's are worth), for $50.00.

Let me know, I am going back tomorrow w/tools.

Thanks Andy. That is awesome of you to offer. I am going to wait. The bolt and go of that other one just got me excited.

Well, if you change your mind, you have until about 3pm tomorrow (EST) to let me know!

it's raining... the damned salvage yard usually closes when it rains - too oily and slick out there.

there is a stealth ram on cf for sale thats been modified for c4's

I saw that too. Very tempting. Probably sell before I have the extra cash though.

Stealth ram --- SOLD. I hate being broke.

broke sucks... so now the $50 intake from the upickit lot looks pretty damned good, eh?

I've got the CAD files for a standard SBC intake, if you eed the pattern for the distributor hole.

The knowledge contained within this forum never ceases to amaze!

I am not sure how I would do the angled spacer though. Looks like LT1intake.com went away...

The one you are looking at, it's not through RedRose on the other forum is it? The one I got from him years ago was advertised much as you describe; distributor hole done, ready to bolt on and go. The distributor depth was incorrect, I didn't check it, and the oil pump drive was only engaged by about .010. The drive let go at 6K on the dyno and I lost oil pressure. That's the reason there is a 383 in my car now.

Regardless, be sure to check the depth on the distributor. A simple paste on the cam gear is all it would have taken for me to see there was a problem.

Josh- the one that I was looking at was on thirdgen.org

Thanks for the heads up!
