So i have a 96 4.3 vortec that im going to pull out of a blazer that was given to be because it had knock and im wondering if it is worth rebuilding or not. Has anyone in here gone through one of these motors and is there any advice that should be known. I have a friend with a machine shop so the labor wont cost me anything and he has a crank for me too. I just wonder if i could find good deal on a different motor and be in it less in the long run...
4.3 vortec help

What are you going to put it in? How much hp do you think you will need? Those are great little engines for power to weight but a little more info would help answer your question.
Well im in the process of building a 95 wrangler... I've got dana 60s front and rear with 4.88 gears and plan on running around a 37" tire. Its just going to be a play toy so it is like its going to be a daily driver or any thing like that. I know the engine makes around 230 horse but they have good torque.

We used a '96 CPI Vortec 4.3 with a th 350 and 3.8 atlas in a buggy and it worked GREAT. the axles we ran 4.88s and detroits. Fun machine.
230 might be a little high in the HP range, I think stock they list it at 190. We did some flat top pistons, went through the heads, and ran 101 octane and had a solid 250 HP when we started racing. Fairly easy enging to work with...

I had southvalley machine go through it when we needed a rebuild. They did a great job. Sorry I can't be more specific. I took them just the long block without intake or front end, it didn't seem to bad cost wise...

your 96 comp sould be th same.
they (howell) striped all the stuff i did not need for off road.
that is some thing u may need to do.
i all so had fun to get my trans to shift.
i got my trans to transfercase adapter out of aplace in logan.
and then had to change out the output shaft from trans to mate to the transfercase.
you did get all the wiring ?
or are you going new wiring

jinx- did you have to replace all the timing gear assembly and cam or did you just use the original stuff.
340six-what was the name of the place you got your adapter at and how were there pricing? ive looked at advanced but they want an arm and a leg for theirs. Ill probably just go the same route you did for the wiring harness I have heard from a lot of people its worth the money.

The engine had 130k on it so we replaced everything while we had it out. It wasn't worth going cheap when we already had it out.
I'd need any spare parts for that engine let me know the buggy is gone and have shelf of parts.

do you need a complete rebuild?
because i can get you an 03 or newer eng compete for $650ish
then change your oil and temp gauges
the only thing i worked hard on was the nock senser.
