Got a 99 2 door tahoe. Its mint but i hate this fucking junk vortec power plant. Looking for mostly fuel mileage. Seeing how its roughly the same price to swap a 4bt and a 6bt, I can't make up my mind.
I graduate in the spring and pretty much already got a job. I could buy something else but I've never been big on car payments. Id rather waste my money turboing 20 year old piles of shit and pounding retail hole.

You think the 96+ Vortec engines are junk?
:?:
Maybe you have never experienced the joys of an early Vortec mill.
Lol.
If you are looking for mileage, then a 4BT would most likely be the better choice. I think I'd rather have the 6BT is the price is no different though.

6bt hands down. More power, smoother running, better support, not much difference in economy in similar sized rigs as that with 4bt's. ect...
-
How hard of a swap is it?

Tell me more about teh Vortec.....

If you aren't doing serious towing you can get an adaptor on eBay for $300-400 to use the gm tranny and then make mounts. Done.
If you are towing a lot then no gas tranny will stand up to the torque without gobs of money dumped in.

Agree on all accounts, not to mention also cheaper most of the time.

I am not saying it doesn't happen, but I have not experienced many failures with those engines, period. The most common issues were the people replacing the spider injectors when the real problem was the fuel pump, and intake gaskets just like any other GM engine of that era.
Fuck a TBI engine. They are the most under powered, fuel inefficient piles of fuck GM ever put into a truck.
I have seen claims of 30 MPG with a 4BT in a suburabn before. No idea how gutless the thing is, nor how gingerly the driver was with the go pedal.

Unless you know where they park the Frito-Lay trucks....

The only way I would run a 4bt is if the 6bt would not fit in the engine bay of what I was swaping it into.

People claim this with full size trucks too, but in reality it doesn't happen. In a 2wd chev half ton, I could see 25-27mpg highway but that is about it. In a suburban I think it would be about the same as the dodge truck it came out of, maybe a couple mpg better at most. 20-22mpg tops.
We get an honest hand calculated 17-18mpg on the highway in the work truck (02' 4x4 2500 ext cab short box 33" tires).

I drove a 63 chevy 1/2 ton the other day with a 6bt and trans out of a ups truck. not fast, but not slow either, 3.08 rearend 30 mpg :Jew:
wish it was mine, I'd slam it on the ground, and crank the boost to nog :noel:
