LT1 in thid gen
LT1 in thid gen Ran into a local partway through this swap and I would like to help him.
Obviously the f-body platform is not my strong point.
Believe it is an 89 and was a V6.
Anyone have pics of the crossmember notching for the AC?
How about a header recommendation. Never going to be a wild car 1 5/8" will be fine.
Was told a b-body PS line will be easier, agreed?
How about AC lines, stock f-body fine?
How about fuel?
Is it easy enough to put a high pressure pump in the tank and just run a relay harness?
How do you hookup the fuel lines to the rail as I assume it does not have the pushon lines. Tap the rail AN?? Adapters? Rubber line and hose clamp
If you think of anything I should have asked go ahead and address it.
Focus for this year is getting it together and driving, I think next winter it will get some gofast parts.
Will be running a 4L60E, engine and tranny are 96 b-body with the f-body tailshaft housing, think we will put a OBD1 pcm in it though so I can scan/log and load for him.

I think if you use the right high pressure rubber or fabric coated high pressure fuel line and clamps you should be fine as far as fuel lines. I have done similar things in the past on my third gens with higher pressure pumps and had no problems. As far as the other stuff, A/C lines should work from a f-body to F-body as the basic design of the chassis was pretty much the same from the third gen to the fourth gen...especially the early 4th gens. In other words...most everything remained at least close proximity to the earlier location as far as swapping stuff is concerned. Sorry I don't know what to do for the cross member and other concerns. Pictures of this would be awesome as you go through it.
You don't have to notch the CM just take a BFH and hit it a couple times just have to dent it (not much at all).
As for headers Hedman 68479 shorty and they are non smog version.I use the B-body ps line works fine you just have to bend it a little.
As for fuel a walbro 255 will do fine for the lines you can get the quick connectors off e-bay use the efi rubber hoses (auto parts store) and hose clamp them or crimp them. There is a few places that sell them IIRC $100.
The radiator hoses are 87-93 V-8 mustang upper for the lower and a 95 camaro Z28 for the upper both will need a little trimming to fit.

Any more input?
I asked here because I don't really have any other cause to go to thirdgen. I know I can find more info there just figured the serious guys might spend time in this LT1 targetted area.

The notching e frame looks way more professional than just banging it with a hammer.
If the 3rd gen was a 6cyl car of course that radiator will not work. The Lt1 radiator does have to stand away from the core support due to the angle on the neck. Alternative woud be to purchase a stock 3rd gen radiator or a Be Cool,Howe etc...
I strongly suggest searching the LtX/LsX swap section www.thirdgen.org they have a great amount of clean and proper conversions.

A 6 cyl radiator will work if it is a 3.1 beeing a 89 probally a 2.8
You have to notch the frame for a ls1 swap the compressor sits back a little more than a lt1. One way around it all would be get the vette acc. But I only know of 1 or 2 swaps that have working A/C's.

How did you route the B-Body P/S line? Do you have it along side the sway bar or attached to the k-member?

x2 for the Heddman shorty non-emission headers and matching Y pipe. They fit much better than anything else I know of and still make good power. Long tubes for third gens tend to hang really low.
Snag a V8 third gen radiator to be on the safe side. Even new they are cheap.
I always wanted to swap an LT1 into a tuned port third gen.....but not run the opti. I was going to mod the intake for the distributor, then just run the whole thing off the computer and harness for the tpi. Cover the opti hole up with the GM parts for carb'd lt1's.
Also x2 on the vette accesory drive. Will clear the frame with no notching.

OK guys I want to bring this back to the top.
The AC compressor with the b-body bracket wants to hit the idler arm bracket with the pulley/clutch and the crossmember with the rear of the pump/lines. I might have a f-body bracket laying around If I do we can try that. Want to try and keep solutions low budget, if someone knows of a Vette bracket and damper hub for cheap would be interested but being "vette" I am sure the prices are inflated.
Will a high pressure pump fit in the fuel tank fine or should we look for a TPI tank for it???
For the steam line I was thinking just "T" it into the heater line, sound like a plan?
Bare with me here, not terribly familiar with the f-bodies but have a pretty good grasp of the LT1. The b-body does a few things different despite having essentially the same engine.

Besides the vette acc drive....the F-body one fits AFTER you notch your third gen crossmember for it.

It should work fine, but if you can get a tank from a 91 or 92 TPI car it will be baffled so you don't lose pressure going around corners with less than a half tank. My 89 Formula 350 was bad about that.
For the steam line I was thinking just "T" it into the heater line, sound like a plan? sounds like a good plan, but I hope someone else chimes in here.

My replies are within your quote....don't think I did that quite right, but you can find it all. lol
