Is there a reason why the hi-miler kits exclude the '93 and '94 LT1? I found a kit for '87-'92, and a kit for '95-'97, but nothing for my '94. Is the hose routing different or something, or are there hoses that are excluded from the kit that I will need? If I can make the '95+ kit work, I'm probably going to go ahead and buy it since I had 101K on the engine before I sent it in for the 383 rebuild.

 

Yes they are different...
Yes it can be made to work[the 95-7 kit]on a 93-4..
Very nice kit, although it is missing one 3/4 heater hose length..
[11 hoses needed 10 in the kit..]
The difference is the drivers side radiator hose has a 'tee' in it for 94[ not for 95],and the bleeder 'tee' for a 94 is a bleeder'pipe[no tee] for 95.. also you do the TB pypass like a 95-7[no coupler needed]
You need to find a bleeder pipe from 95-7, and route the hoses as in a 95-7..
Do a search.. I covered this recently in more detail [search LT1 tech for 'Goodyear hi miler'..]
It;s hard to Dremel those crimped hose clamps off while on the car, but not impossible...
Also, look at shoebox' tech page, and study the radiator and heater hose diagrams...

The motor is coming out and then going back in, so I should have decent access to everything. Thanks for the detailed explanation...it beats all of the other answers I've found so far!

 

Motor out it'll be easier.. and you'll find that the 95-7 'configuration' is better than the 93-4 anyway..
Hose set is VERY good for 100 bux..
Also, I had contacted Goodyear's engineering dep't about the 'missing hose' [they MAY have added the missing one... IF you get it and theres 11 hoses please let me know so I know that I did some good contacting them!]
Do the search.. I wrote more about it in other posts..
THE PLAN was to do a writeup on the replacement, and 'conversion', but thats on my 'to do ' list still..

EDIT:
To use 95-7 configuration on 93-4 you need a 'heater outlet hose
connector'[bleeder pipe] without the 'tee' on it, that the 93-4 has
[The 95-7 one doesn't have a tee] it is GM p/n 10262478 $35.07 GM list, about 18 or so from Jason Cromer..

 

I will let you know how many hoses the kit comes with when we get on it later this week (or early next week). I had searched through your previous responses and saw that you had mentioned that. Kind of sucks that they didn't get the kit complete the first time around...hopefully that's fixed now.

About this "heater outlet hose connector"...on the '95-'97 hoses and pipes diagram on Shoebox's web site, which part is that (as in, which number on the diagram)? I can't really place which piece you're talking about. Is it something I *have* to buy, or could I weld up the old tee or something? I'd rather not have to order one since I know it won't be here in time for the weekend.

Thanks for all of your help so far...it's greatly appreciated!

 

It's the 'bleeder pipe' [# 4 on both early and late heater hose diagrams on shoebox' site]
Early is a 'tee' later is a 'pipe'
You need the pipe since you don't use the 'tee' on 95-7..
You could cap it, or put a short length of hose on it, and plug it for now I would think..

 

Cool...I'll most likely just cap it since I'm a cheap bastard.

I'll let you know how everything turns out and if they include the extra hoses in the newer kit. Thanks again for all of your help!
