The motor in my 95 k1500 has 215k miles and is getting tired, I'm debating rebuilding the TBI engine with new rings and bearings and staying with the stock 200hp, or putting one of my LT1s in it. I'd like to stay fuel injection, but I can't really use the opti since I need to be able to plow through puddles. I want to spend as little as possible, less than $1000 total no matter what I do since this is a beater and I have alot of parts laying around. I'm starting to read about using a vortec dizzy, and the opti just for the crank position. Is it as simple as that? Or does anyone have any other suggestions? I'm putting a $1000 cap on this since any more does not justify just going to a junkyard 5.3. I'm not looking for a ton of power, I don't want to have to change or rebuild my 4l60e. The LT1 I would use is the one in my car now, I have another one with heads/cam to replace it. I have optis, waterpumps, brackets, alternators, everything but a harness for the lt1 swap, but one big puddle in the open engine bay of the truck and the opti is a goner. If I rebuild the tbi engine I would just do headers and a couple throttled body spacers stacked and call it a day. I only tow 6000lbs every now and then and don't need 400hp.

 

Repin LT1 harness for 24x, run their crank reluctor, get teh AC delco crank sensor, and run a single plane with a vortec dizzy. Source the coil packs/PCM/connectors etc for cheap and you could def do this for under a grand. Toughest part would be making either the single plane for the LT1 or drilling an LT1 intake for a dizzy.

 

Is there any way to use the stock PCM? I'd rather just keep the same tune I have.

 

Just seal the opti. Dielectric grease on the weatherpak and light silicon bead on cap.
