Hello everyone. I'm posting here mainly to see if anybody can help me, or if anybody can point me in the right direction I need to go lol.

My friend has a 1992 chevy s10 regular cab short bed 2wd 4.3 auto with 170k miles on it he's trying to sell, and im thinking about sliding him $800 and taking it off his hands. The truck needs a brake booster (vacuum leak in the booster), fuel sending unit (new pump but the gauge doesn't work), a windshield and one tire to be a daily truck. He's done a lot of work to it recently but he wants something else. New edelbrock timing chain set, valve stem seals, new fuel pump, new cooling system, all the fluids flushed, new front pads and rotors and wheel bearings, new transmission and probably some more, it's fairly clean and well taken care of. However I want to ruin that streak and turn it into a drag truck. So I just want to know what all I really need to do with it, or where I need to go to ask someone else lol.

I want to convert the rear drum brakes to disks, upgrade both the front and rear brakes, put bigger tires and lighter wheels on the back and skinnier tires and lighter wheels on the front, slam it with some beefy lowering suspension, change the gears in the differential or replace the whole rear end, and either sell the v6 and trans and slap a ls 5.3 and 4l60e in it, or just turbo the 4.3 until it blows up and then slap the 5.3 in it lol. Just trying to see what the best options would be. I know I can't mate the 700r4 with an ls 5.3 (and I would want to if I could lol) so I would probably end up using a junkyard engine, junkyard 4l60e, and I'd like a holley terminator x max to power them both, but stock the 5.3 is almost a 200hp gain, for $700 lol. $3.50 per horsepower basically. With a cam and headers push it to around 500hp at the crank no ac or ps.

But the biggest thing I want to do first is get it running good with the parts I mentioned earlier replaced, upgrade the brakes, then lower it, then make it fast.

Thanks for any help you guys can give!
