Ran across a deal on a Tahoe and a Yukon... One was a 95 and the other a 96... other than the fact that one is a Chev and the other is a GMC, I didn’t expect there to be a difference. HOWEVER... I found out that the 95 Tahoe has a Throttle Body injection Motor... and I have no experience with these and don’t know much about them.
My questions: Are Throttle Body motors less (or more) reliable than the Vortec? (I have a suburban with the vortec 5700 and it’s been indestructible)
Is there a reason I would want to pick one over the other?
I would be doing a bit of towing... which is the better pick? I would also be doing a lot of long distance highway trips... Is there a difference in the mileage?
Is there anything that i need to know one way or the other?

i'd go w/ the vortec. both are very good, but the vortec will get better fuel mileage.

Some of the vortecs also use throttle body injection. If one engine is a vortec and the other is a pre-vortec, the difference is about 50 horse power. The truck 350's were rated around 200 hp before the vortec heads, and 250 hp after. Vortec engines are not more or less reliable than other smallblocks. Vortec just refers to the cylinder heads. These heads are exceptional for a factory head. All the budget racers love em.

Go with the Vortec. More power, better mileage, and just simply more reliable.

TBI engines were a quick answer to fuel injection. They work on the same principle as a carburetor with one injectorbut are not as efficient as tuned port injection...each cylinder has an injector.
Vortec engines are 2 generations after TBI so are more efficient and powerful in high rpm range.

id chose the vortec..
the old TBI motors are crap. thats why they were replaced. the vortec can tow much more.
and the vortec would get better gas mileage

isx650 is correct. both are vortec in those year models. the throttle body will cost you more fuel.
