2.8 vs. 4.3

Comparing the late 80's 2.8 against the late 80's 4.3, how is gas mileage compared? HP? Reliablity? just over all pros and cons of both engines????

Re: 2.8 vs. 4.3

The 2.8 makes a good boat anchor, does that count? It isn't worth its weight in scrap.

I'd rather have a 2.5L four cylinder than a 2.8V6.

My Mom's 4.3L S10 Blazer with 190,000 miles gets around 16mpg city. The mains are probably so sloppy that no more bearing material even exists. Oil pressure is a solid 20psi but when it's cold outside it takes a couple minutes for a lifter to pump up. Buick's 3.8 and Chevy's 4.3 are the best V6s ever made.

Re: 2.8 vs. 4.3

I had an 89 Gmc Jimmy with the 4.3 and Was really impressed with it and i agree that the 4.3 is one of the best ones v-6's made
As far as the 2.8 They seam to be a half way decent motor in a 2wd corsica or cavelier but as soon as you put it in a 4wd You better start looking for a new motor Fast ....It might last but i know some one that replaced 3 2.8's in one year in an S-10 4x4
