When LT1 intakes are converted for L98 use with a distributor, where do they get the measurements for locating the hole for the distributor? And if I'm not mistaken, where do they get their info on the correct angle, if any, for the where the dist. collar rests and is tightened to the intake? These questions are the biggest reasons I've never looked too seriously at a converted LT1 intake.

it's a bit of a hit/miss process from what I understand.

You line up where the dist shaft goes, and it is vertical to the drive from the cam and oil pump... Add a touch of wiggle room, and then tap in a bolt to hold the dist to the intake... that's where the angle plays it's game... some simply get a piece of machined aluminum, like a thick washer, to make up the gap, a little gasket or RTV and that should be that.

I am sure if you do a google search on LT1 intake on L98. I am sure that the dimensions you want are there. Also, you might want to add a coolant line that spans the intake - this would cut down on pressure building inside the heads, remember the old L98 intakes are wet, and the LT1 is dry. Drill a hole, an AN fitting, some nice braided line to span the distance. It would keep the L98 coolant flow consistent.

I don't remember the details regarding head bolt to manifold fitment... I know mods are required when adapting to a Vortec head.

There used to be a guy who did/sold them at www.lt1intake.com but that site is no longer there

You have to drill the dizzy hole (accurately) and they used to sell a metal ring to weld on there to make it flush (used to be on ebay but I can't find it now).

Here's an article, not super in depth but has basic ideas:

This guy recommends using a standard manifold as a template:

Read that and you'll be an expert

Thanks Andy. I'd imagine the you can transfer the bolt holes from a gasket for the hold down bolts. The dist. hole though, I'm not sure where guys get their locations. I'd guess you can flip an oem over and, taking measurements from the manufacturing of it, generate the needed location.
It's not so much that I wanna do this myself, but I've considered buying one already converted, but then my original questions come back into play. How do you know it's been done correctly?

Did you look at what I posted???

Hi Matt,
I did look a good bit at what you posted. I'm pretty sure I'm gonna need to go thru an do it again as well. And don't think I don't appreciate your post, but we had my daughter's annual party here at the ranch, which means I was either cleaning or out shopping for supplies for both the party AND to help us get thru the lack-o-water due to a main break a few yards from our house. Lemme tell ya, yesterday we had "Grand Lake dayton" at the base of my driveway as there was prolly about 50+ gallons/minute going by. Thanks to both of you for your responses.

Sorry, after I read that post it makes me sound like a dick. I didn't mean it in a negative sense, more of a "oh my gosh, it's all right there, didn't you see it?" kind of way. Sounds like you were quite busy so I understand. Pretty much all the info you need is in those links.

I did see a guy selling a complete converted setup on CF the other day for a good price, though.

Thanks, I saw that one, and there's been another for sale as well. But in keeping with my opening post, I still wonder if these intakes have been done correctly, or "close enough," if you get my drift. I guess I'm just gonna have to break down and join in those threads to find out how they were done.

That's a hard one to call... unless you know the machinist.

I would almost do it my self if I knew a good CNC guy. Which I do...

If you need one, I have an COMPLETE LT1 intake, with rails, OEM injectors, EGR valve, throttle cable bracket, MAS, MAF, throttle body with IAC and TPS. Fits all LT1s but is specifically 1994-96.

I am a fan of the EGR valve, I think that a kit might exist to relocate the valve from where it lives to a more or less remote position.

I haven't fully made up my mind to go this way, but just out of curiosity, how much would the selling price be for that setup?

That's a good question... I don't know the prevailing price range right now. I will research and get a good number.

Just in case you're interested, just saw a converted LT1 intake on that "other" forum. In the C4 Parts for Sale section.

Thanks Joel, but for now, things are on the way back burner. There's also a guy trying to get a group purchase together on that forum for FIRST intakes. I'd really like to get in on that, but I don't have the $$ to go that route.

The first is nice, but it is not plug and play either. You need to modify the fuel lines, fuel pressure regulator, etc. Also the TPS is mounted goofy under the tb and is a pia to set. But seems to perform well.

If looking at the first, I would also consider the edlebrock pro flow.

The Pro Flow has been looked at, but again too pricey after all is said and done. I've gotten to the point of either keeping the SuperRam, or maybe a set of ported out SLP's that aren't siamesed too badly. I like the idea of the low-end torque, and from what I've read, they'll rev up to just about where I want them too. This is one of those decisions that probably will not be final until it's all bolted down.

Keep the superram. When I went from my ported SLPs to the SR the difference was very noticeable. I wouldhave never switch back.

If it ain't broke....

Thanks for the input. I'll take this as sage advice.
