OBS conversion success

[RedHeartbeat]

Well, the newly rebuilt 1998 LS1 and transmission are installed and working great! A little bit more fine tuning by the master programmer will be needed to finish it up.

I installed the Auburn limited slip diff this after afternoon. Found out I have 3.42 gears. 12 pinion and 41 ring gear teeth.

I started out with a 1998 PCM and harness. I sold the 1998 PCM and got a 2002 PCM from Allen. I repinned the 1998 harness as a 2002 harness.

There now resides in the transmission a Kevlar band, Kolene steels, Red Alto clutches and 9 clutch OD pack. The Transgo 4L60E-HD2 kit is fully installed with the .500 boost valve and clutch apply springs from the kit. There are now 2nd and 4th gear apply pistons from Superior and PATCO installed. All the plastic pistons have been removed and replaced with pinless accumulator pistons. The Precision Industries Vigilante 3600 torque convertor is HOT!! When I get on it the transmission acts like I have a stick shift and have side stepped the clutch.

The engine has rebuilt heads, Comp cam, 7.400 Comp pushrods, Manley dual springs with titanium retainers good to .650 lift, ARP rod bolts, LS2 20% larger volume oil pump, LS2 complete timing chain and sprockets, the crank was ground -.010 mains and -.020 rods. Stock pistons that were glass beaded were re-installed with the 100,000+ mile rings since everything was in perfect condition in the cylinders. I am using the stock F-body manifolds. For the intake I have a 90 degree silicone elbow to MAF to 3.5 tube to K&N filter mounted next to the fender. I mounted the air temp sensor by drilling a hole in the aluminum tube and putting a rubber wire hole grommet the appropriate size for the sensor.

I installed the 2005 electric fans and used the wiring diagram I posted earlier. It's working really sweet. I need a little sheet metal work done to mount the fans in permanently since there are no mounts to clip the lower section of the fans into the clips. The top mount to hold the new 34" radiator and electric fans also needs to be fabricated. The new radiator has fittings for an additional cooler on the driver side.

Next on the to-do list is to install the NX nitrous kit. I am thinking of going straight to the 150 HP pills. I am hoping that has me at 600 hp at the crank but that might just be wishful thinking.

The truck came equipped with a Gibson mandrel bent exhaust system. I had a muffler shop build a y-pipe. It looks a little cheesy but it works for now. It's 2.5" tubing both sides and merged by cutting out the area it met up with and then welding it together.

All I have to say right now is WHEW!!!!! It took a while but the results are worth the time and effort. The family has suffered but they know my pains and anguish after the other truck being stolen and that I would never be happy with the stock 1993 drivetrain.

wow, looks like your hardwork paid off, good job i bet that thing is a rocket! tranny sounds bullet proof. im kinda new here, what was yor old truck and how it get stolen? that is but its good to see you got a nother project to play with.

[GMCwantsLS1]

Good job! I'd love to be on my second conversion, but not the way you did it (truck stolen and all). We'll all have to meet at the track again soon!

[RedHeartbeat]

The old truck is the one in the avatar picture. I bought it brand new in 1992. Its a Victory red 92 xcab with 2000 escalade front clip, lowered 4/6 with chrome 1999 Corvette wagon wheels. It had a fiberglass tonneau cover. The engine was a 1998 F-body LS1 that I had put ported 2002 head upon. The transmission was built by me with most of the goodies I have in the new one. It had an Auburn LSD with 4.10s. For fans it had Camaro dual fans on a 34" radiator. I used the 1LE Camaro intake elbow which I bought for about $50 with the intake air temp sensor included. The stereo had two Audiobahn amps with Polk 4x6's and 2 10" Kicker CompVRs being enticed by a Panasonic CD head unit.

It was stolen in front of a salvage yard while I was picking up an engine for my son's car on Friday qualifying day here in Dallas during the spring race. Not one part of the truck has been found.

That's awesome Red!!!!

A stall with the LS1 is great! Keeps it in the power band all the time.
I know you live a tad north of me, but try to get it down here and we'll throw it on the dyno and fine tune it. Or meet up with us and we'll tune it at the track!
Or, just let me know what needs to be done and we'll get you another PCM.

Congratulations on the truck, I know it's been tough,

Hey Red thats awesome man. Hey what a way to start the brand spankin new 06 than with a kick ass truck! Hopefully someday Ill see it. BTW I got less than 2 months left out here in asscrackistan, WHOOOOHOOOO!!!

[RedHeartbeat]

Well, lets wind the clock up a little tighter and get your stint finished up over there so you'll be back here in the states just in time for race season. I know Super Chevy Show starts up in the Houston area some time just after you get back. That's a great show to attend!

Glad you got things together RHB, sounds sweet!! I'd like to see some pics. I finally got time today to work on mine. I was wire wheeling the frame on the passenger side and had a ground strap out of the way. I guess the windage from the grinder let the strap loose and it got caught uo in my wheel breaking the strap hitting me in the leg and then breaking 2 fingers on my right hand with leather gloves on. LOL What a bitch!! I still kept working and got the frame and crossmember painted. I need to paint the outside of the frame tomorrow and I'm ready to put the suspension back underneath it. I'll have some pics in the next couple of days for ya'll to see. I can't wait to meet you at the track when I get mine together so I can crack your ass!! LMAO Just kidding but it would be fun to race.

[RedHeartbeat]

Owww!!! Damn Lance, at least you had you're gloves on. I am glad to see you had time to work on it for a little while. It's a shame you got injured while doing it. I'm glad you were working smart. You easily could have lost those fingers instead of just breaking them. I caught my finger with the cutoff blade on my 4-1/2 grinder while cutting an exhuast pipe off. The wheel bit and then the blade and grinder came at my other hand. Luckily all I have is a scar. It easily could have taken the finger off, too. I wish I would have been wearing gloves that day. I do wear safety glasses all the time, though.

[NITROUS]

You were lucky too!! I had safety glasses, ear protection and gloves. I'll be OK, thanks for your concern. I can't wait to drop the motor in. I'm sure it will be at least another month before it's all together. We're fixing to start making gasoline again and you know what that means O.T. $$$$$$$$&# 036;$$$$$$$&#03 6;$$$ I hope I'm ready by Super Chevy, it would be awsome to meet you and some of the other guys there!
