Starting S10 LS1 swap, what manifolds / headers? Starting an LS1 swap into my 94 S10 and can't find any good info on what manifolds or headers to use. JTR has some headers on their site, but it says they are 1.5" primaries. I think I've also heard that those don't fit that well. I bought the motor mounts from carshop on ebay. Here are some pix of the truck so far. I bought it with a bad engine.

JTR is the only company that produces a header for S10 swaps, and from what i gather from some dyno charts i've seen there barely better than stock manifolds...so there basically a waste. '98 f-body manifolds fit with just a little modification, you basically have to cut the flanges off the bottom and replace it with about a 10" section of tubing for clearance on the upper a-arm. I've heard you can just grind on the washer behind the bushing on the drivers a-arm but im kinda against that. The only clearance problem you have is the drivers side, passenger side fits really good with the proper tubing bent up.
Your only option for big primary headers is to buy a weld up kit from someone like HeadersbyED.com. I got a weld up kit from him but haven't installed it yet because my projects been on hold for a year or so, real nice kit. He water-jet cuts his flanges and you can get flanges up to 1/2" thick, got mine with 1 3/4 primaries and 2 1/2" collectors for better bottom end. They come with enough tubing for 36" primaries.

I had read somewhere that the F-body manifolds would fit with some work. The truck had some hedman 1.5" headers on it. I have even thought about ordering the flanges for the LS1 and making those headers work. I would rather run the manifolds. I think I'll have better steering clearance with the manifolds. Thanks for the input.

You might want to get in touch with Eric at http://www.turbotime.us/
They are working on Syclone Typhoon conversions (which use a 4x4 frame which is slightly different than your 2wd...but some of what they're doing might help). They have adapted a hydroboost system off an Astro Van which frees up a bunch of room around the brake booster...that should really help with your header clearance.
Good Luck!

I have pics of some of the problems I ran into and such. Even with the Sanderson headers I had clearance problems on the driver's side. www.geocities.com/jays_s10/ls1swap.html it's almost ready to go, just waiting on the headers to get back from Jet Hot and we will see if this bad boy will breathe or not hehehe.

Im going to be following pretty close to your design just for simplicity, i very seriously doubt i'll loose much power by having one primary a little shorter than the others. Im using 1 3/4 tubing though, so i should have ALOT of fun...lol.

Don't forget he also lies a lot, over promises, and takes 3 times longer than you think would be a long time. He has a Monte Carlo there now that is having it's 3rd birthday this year, just for an LS1 swap.

Lee's is nice, but no way in hell i'd pay his prices on parts so simple as motor mounts and no way i'd pay him 20g's to put an lt1 in my truck and even more for an ls1 (going by prices on there awhile back). Simple fabrication and common sense and you have yourself a swap, just as cleanly!

Actually Sanderson is working on some. I think they make them for JTR. They should have a set of 1.75 headers ready in about a month. I was told they have the driver's side done, but not the passenger. I'm waiting for those. They are pretty cheap too. I think the were around $400 coated and $300 uncoated.
