Lt1 inakte, again.

I did a search about this conversion fot the TPI. And I found alot of talking and not much real life experince.
Has anyone used the lt1 intake conversion that use the car as a daily driver?? And put alot of miles with it?

I looked at www.lt1intake.com and saw that he ( john ) hade to make a new style shim to stop a oil leak? Where whas that oil leak? And why must you have it on a 5° angle?

And can you use the intake with ported 113 corvette alu heads?

And second. Is there any reason you whan to get this manifold instead of the HSR, I know the HSR is a bit more in price, but with the hood probleme on corvette the lt1intake mayby is the way to go?

Thanks..

John has put (I think) over 15,000 miles on his car with the intake, and there aren't any problems. The shim is needed for the distributor. It comes out at an angle, so the shim must also be angled. The intake will work with the vette heads.

Greasemonkey is right. I do have a daily driver with 15,000 miles on the LT1 intake.

He is also correct about the distributor angle. All gen 1 SBC's have the distributor at an angle. I didn't know this at first and made a flat spacer, the distributor didn't sit flat on the spacer and I had an oil leak.

some more questions..

Will the TB linkage not bind against the coolant hose ? Do you have to use a angle type of fitting on the hose if you have a stock TB?
How do you solve the probleme with the throttel linkage? Do you just unbolt the hold linkage "holder" from your TPI and bolt that on the new lt1 intake? Do you have to shorten the wires?

And will the fuel lines John sales fit the corvette set-up? They have to be really long compared to stock set-up. Wount that hurt preformance?

Is it hard to set the timing due to the fact you have a small distrubitor and the hole in the lt1intake is for a big one?

WHere do you put the t-house that John sales? And is there any probleme with coolant distribution on the engine? It seemes like the front of the enigne will have "more" coolant liquid going around then the back of the eninge due to the coolant routing..

WHat gasget do you use with the corvette alu heads and the lt1 intake?
And can you be sure you dont have to re-drill or file the holes on the intake, like some have?
Where have you ( john ) used JB weld on the intake? And will that hold during a long time of operation? Mayby its better to weld there?

Is it just to cut the wires that goes to your orginal distributor and solder them in to the '87-92 Camaro type of distributor? Is it the same colour on the wires?

What kind of adjus fuel pressure regulator will fit?

Hope you can help me..

Thanks--

devil..

John puts the fittings in the back of the intake now, so the TB linkage is not a problem.
Do you just unbolt the hold linkage "holder" from your TPI and bolt that on the new lt1 intake? Do you have to shorten the wires?
No, pick up a throttle cable bracket for a 93 F-body. I'm not sure on shortening the cables.
And will the fuel lines John sales fit the corvette set-up? They have to be really long compared to stock set-up. Wount that hurt preformance?
You have to ask John about the fuel rails, but I'm betting they'll fit. No, long fuel rails will not hurt performance.
WHere do you put the t-house that John sales? And is there any probleme with coolant distribution on the engine? It seemes like the front of the enigne will have "more" coolant liquid going around then the back of the eninge due to the coolant routing..
Mount it wherever you please, I'd just try and keep its height about where the T-stat is now. Coolant flow can be kinda complicated. Do a search.
WHat gasget do you use with the corvette alu heads and the lt1 intake?
Felpro 1205 most likely
And can you be sure you dont have to re-drill or file the holes on the intake, like some have?
Thats probably for the center bolt holes for the older style heads. If you tell John the correct style of heads, he'll set the holes up for that style.
What kind of adjus fuel pressure regulator will fit?
An AFPR for a 94-97 LT1. I'm not sure if the vette is different than they F-body's or not.

thanks

The next step is to find a nice cam to go with this.
The lt4 hot cam is expensive here in Sweden.
What should I use?
The comp cam 305 looks ok.
I can have a custom made cam aswell.

Keep this in minde when help me pick a cam

car is

corvette 1991
ported 113 alu heads
1,5 rr
headers
lt1 intake.

I dont whant to machine my heads to fit larger springs. So what ever aftermarket springs will be fine as long I dont need to put larger springs in..

I got accses to crane and comp cams..

since you have a stick, get the biggest cam you desire. you can street a big cam alot easier in a standard than an auto. i would also look at the cc306 or the comp cams XE grind that has like 236/242 duration at .050, thats not the actual duration, just off the top of my head it sounds somewhat right.
