If somebody could post some pictures for me, I would appreciate it. Email me and let me know.

This installation took me a solid 5 days to complete. I took it all apart on Friday, May 14. Then spent Saturday and Sunday getting it bolted on. Didn't work on it again until this past Friday evening, and completely finished the manifold installation at about 1:30 a.m. Sunday (Saturday night). Spent all day Sunday changing the knock sensor (somebody way over tightened that thing before.)

My complaints about the work that John did were these:
1.) He did not drill the mounting holes perfectly and I had to oblong several of them.
2.) He did not grind the bolt surfaces down parallel with the gasket surface.
3.) The distributor hole is too big. It is super hard to set the timing, and I'm really sweating over the distributor/cam gear wearing too much. It is something that I plan on checking after a few miles.

I will say this about John (this is the guy who owns http://www.LT1intake.com if you don't know who I am talking about). He seemed like an honest person who wanted to help me out in the installation of this intake. I was having a few problems with the Corvette/Camaro differences, and he offered to send me Camaro parts to try, but I was able to get my stuff to work through modifications. I can definately say that on a business level he is a standup guy.

After I got the Intake on, I noticed that the throttle body would not work without modification. What I was able to do was remove the cooling line nipple that John had installed and put in a 45* elbow in its place that allowed the trottle cable mechanism to function without hitting the line. You can see the pictures of what was in the manifold before I changed it, and what I changed it to. I left the passenger side nipple alone.

When I went to install the air pump, it hit the cruise control cable holder. I ground this off, and installed it backwards. Not a big deal. One thing though, that material is as hard as a minsiter's d!ck. I used up a whole dremel stone just getting it off, and there was no way I could drill and tap it to put a bolt in it. So I just epoxyed it back on. Seems to be strong enough.

One of the differences in the L98 and LT1 I knew I would have to address was the distance from the throttle linkage bracket to the throttle body. I just bought the LT1 bracket, cut the L98 one up so that I had the holders for the cables correct, and I bent a piece of flatbar to give me a 1 inch space to correct for the difference in length. I have a picture of this too.

Using the Corvette fuel lines presented a problem with the placement of the schrade valve on the fuel lines. You can see in the before and after pictures what the problem was, and how I bent it to solve it. This was just a quick fix that I may try to buy another line somewhere and braze the valve on in another place so that it looks better.

So how does it run now yu ask???????? :D :D :D :D :D

It runs like a champ. Car feels quicker, but at the same time, I can feel the difference in the loss of instant torque, but it doesn't peak out real quick like before. Its just a little bit less torque, but its all there all the way through the power band. It doesn't fall on its face like it did before. I love it. :D

Shoot some pics my way and I'll see if I cant get em up here for you in the morning (when I get home from work)

More Info please because I'm thinking about doing this:
1. What size fuel injectors?
2. What type of distributor and coil?
3. Did you use a bigger throttle body?
4. Dyno numbers?

SpedRacr93

1. 24 lb injectors
2. MSD Pro Billet Small Diameter HEI distributor
3. GM coil
4. no, stock throttle body
5. Dyno, don't know, only finished it 2 days ago, but no plans for a dyno run unless I can make another forum dyno day at MTI in Houston. I expect in the vicinity of 300 at the wheels for both torque and horsepower. Before, I made 260 hp, 350 tq. and I had a small false knock too due to an overtightened sensor.
I will post quarter mile time when I get that though.

:cool: I've read another doing this mod on the thirdgen.org board.

Nice job, thats very impressive. Can you post a pic of the thermostat relocator please? What all, besides what you've mentioned allready, did you have to buy or replace in order for that mod to work? :cheers:

Could you just use an LT1 throttle cable and cruise cable instead of making a bracket?

SpedRacr93

Nope, LT1has throttle and cruise go through ASR module, and then one single cable goes up to the throttle body.

I guess you could say you have a LT-98 now huh! :lol: :lol: :lol:

KYVette90, I don't have the driver to upload pictures here with me, email me and I will try to do it this weekend.

I spent quite a bit on little stuff like heater hose, pipe nipples, and little stuff like that. Hell, the tap for the cooling sensor that I put into the thermostat housing was $35. What sucks about projects like this is that a lot of stuff that you buy you end up not using and you spent money on something you thought would work, but didn't.

In all honesty I didn't keep track of what I spent because I didn't want to know. I just knew I didn't want the T.P.I. any longer.

The GM stuff I bought was expensive too. Those LT4 fuel rail covers were expensive, then a lot of GM fasteners I used were overpriced too.

As far as modifying other things, I really can't think of anything else. The distributor was easy, I just went to a junkyard and cut the wires and plugs off of a late 90s pickup truck wiring harness and soldered them in. All of the wires are the same, just the plugs are different. And I mounted the coil to my AC bracket and just ran the wires under the fuel rail cover.

Its also important that you drill holes in the thermostat because you must have flow to get the warm water to get to the thermostat.
