Been there done that.
waste of time and money.
yank it out and LS swap it, cost far less, makes far more power.


whilemit is fun to surprise ppl with, “yea its a v6”. Its a serious waste of money.

I'm pretty sure typing "99 4.3 s10" into google would have yielded more information.

They're great engines for small trucks. I had a 99 2 door blazer and while I always wanted to LS swap it, but the 4.3 power was just fine for my uses and got about 20mpg with a light foot and few mods like electric fan, underdrive crank pulley, modded airbox and filter, and free flowing muffler. The same engine in a RCSB s10 would have been pretty quick.

This engine came in two versions, the LF6 rated at 175 hp (130 kW) - 180 hp (130 kW), and the L35 rated at 180 - 200 hp (150 kW). Only the S-series pick-ups used the LF6, while the full-size trucks, vans and Blazer and Jimmy used the L35 version. The L35 was optional on the S-Series trucks.

My son has a 4.3 S10. It is PITIFUL. Granted, his is a TBI one; but still. It's PATHETIC. It's not detectably better than a 2.8 as far as I can tell, and not any better really than my step bro that has a 3.1 S10. Still totally inadequate. It's bad enough in the minitruck, but can't begin to imagine what possessed some "engineer" to think it was a good idea to put that steaming bucket of horse plop in a full-size truck. AFAIAC they should spend their eternity in Hell driving one around while everybody else gets LQ9s and L92s and such. Definitely not a topic for "performancetrucks.net". Maybe "gasmileagetrucks.net" or something.

I thought someone here said the 4.8 gets better gas mileage than the 4.3. It's a topic for "mashingthepedaltothefloorwaitingfortheothertwocyli nderstokickin.com".
