Well, after moving at a glacial pace for most of this year, I have some genuine progress to report on my S-15 swap. First up is the A/C compressor bracket. I didn't want to mutilate the frame any more than I have had to already for oil pan clearance, so I decided to mount the compressor up high like a 4.3 S-truck has originally. After looking at John B's bracket, (thanks for the inspiration, John!) I made one to hold the compressor higher and that would line up with the Corvette accessory drive needed for this chassis. The bracket is made from 3/4" aluminum plate, mounting an LT1 compressor and LT1 tensioner. The original Corvette tensioner is now an idler. Down next to the crank pulley is an additional idler I made to hold the belt away from the thermostat housing, mounted to the original compressor bracket. It took many hours on the milling machine and lathe, but I'm happy with the results.
Next are the headers. 1 3/4" longtubes, 3" collectors, entirely of 304L stainless. I'm no stranger to fabrication, but this was a challenge. Starting with a big box of bends, a pair of flanges, and two collectors from Stainlessworks (>-----sponsor), I cut, fit, tacked, and finally welded out a set of headers that clear everything, (even the upper A-arms at full suspension compression) and should help me get the most from the heads/cam swap that is planned. Now it's on to the rest of the exhaust system.
More updates as they happen.......

Hi David, NICE WORK, Is your steering shaft going to run thru the headers? Gonna be tight. I have a awd 93 that I'm working on, Ive been at it 1year this month. the headers are a real problem. I've tried about every oem manifold made. none will fit,i also have the shock towers to contend with. Pics of my truck at turbols6.com click on gallery, scroll down to TYHOONZ06. THANKS

Your truck looks good. Did you think before you started it would be as much work as it has turned into? Years ago, when I put the L98 TPI in my truck, it wasn't half as hard as this LS1 is turning out to be. Even though, I think it will be worth it when it is done.

Yeah, but even if I could get $400 each for them, (fat chance!) I'd still lose my a$$ because of all the time I have in them!

Does Lees High Tech have a website... or contact info? Please PM me.
Wondering if the pictured A/C bracket would fit in an 03 S10? I'd buy one

Does Stainless Works make a set of headers that will fit in the last model S10's? I haven't talked with Al in awhile... maybe I should give him a call. BTW, nice headers

Looks sweet! Do you have to take the body off the frame to do the swap? I want to know how hard it would be to swap a LS1 with a M6 into a 1992 S10 4.3L (longbox). Any idea on 1/4 mile times?

No, it was just easier while I was fabbing up the headers to raise the cab up off the frame with the lift after checking fit. The LS1 swap isn't all I'm doing with the truck. Many other mods, plus bodywork, paint, interior, yada, yada, yada. Maybe one day I'll have it back together......
It isn't really hard to swap into an S-truck, but it is a lot of work to do it right. Anyone with decent mechanical skills and lots (lots!) of patience can do it. Oh, yeah, don't forget to bring a bunch of money!
With a stock LS1, quarter mile times will be roughly similar to a stock LS1
F-body. The S-truck isn't as light as most people think, unless you have a 2wd regular cab short bed with no options. My 2wd extended cab with most power options was over 3400lbs.

I second the weight thing. Even though my truck has the half fiberglass stepside bed on the back it weighed about 3430 with me in it I'm 200 lbs. So the truck is about 3200 even. That's a reg cab truck with a 4.3 in it. It's not super super light like most people would think. I would compare it to a Z06 in terms of weight more than anything but again I have probiably the lightest combo truck you can get out there.
Also, I would like to comment on Lee's High Tech. The guy does great work, but he doesn't get things to people in the most timely manner alot of times. Now, his stuff is expensive but you do get what you pay for also. He may not even have a set of LS1 headers out yet. I know they were talking about it but who knows if anything ever came of it.

Thanks for the info.I presume it would be cheaper to swap a 350 or 383 stroker into a S10 then it would be to do an LS1 swap. Can the price of an LS1 S10 swap be ballparked?

I'm doing this on my 91.. but as for the weight comment, the weight of my truck right now is 2650 with me NOT in it. all stock
are you building it for just something nice or bagging it or are you coilover/4 link/hot rod style? I'm doing mine for 1 season of racing in the Super Stock class in the EFI nats, then its to do it the way i want.. shockwaves all around, 4 linked, etc..
nice work so far, it looks reallllllly good.

you're looking at ~3500 if you have the 700r4 and want a stock swap... even more if not... i'm building mine piece by piece.. gonna cost more, but its what i can afford right now. (dont forget motor mounts and the nickle and dime ****)

dcdime Thanks for the price range. What style suspension are you going to use when you race in the EFI Nats. I've seen a bunch of S10's at the drags in super stock or stock class.They had wheely bars and pieces cut out of the rollpan so that the wheely bars could move.
