4.3l to 2.8l Swap
 

How Practical is it?
LL2
The carbureted LL2 ("R-code") was produced from 1982 to 1988. Another LL2 ("R-code") with throttle body fuel injection was produced from 1986 to 1993. Output of the TBI version was 125 hp.
1986–1993 Chevrolet S-10/Chevrolet S-10 Blazer

this would happen in a 1989 chevy s10 blazer 4x4 4.3 engine Vin "W"

this is just a thought.
Thank You

why would you go from a 4.3l to a 2.8l. that doesnt make a whole lot of sense....:eek:

never said "I" was or am, Just a thought, always seeing guys going from 262 to 350's just wondering if anyone ever went down :icon_banana:

i would think that if they went down, it would be from a 350 to a 262. i personally have never heard anything good about the 2.8l. and pretty much every one knows that the 4 banger doesnt have any guts to it.

The only time they go down they still go up. thats when they swap in a 4bt diesel (pretty much a 4cyclinder). but I have never heard or read of anyone going down. always up. but whatever floats the boat

Ill take a 60 degree over any 90 degree v6 but I wouldn't swap one out. I'd pull a boat anchor 4.3 for a v8 any day of the week tho.



I don't understand why taking going from completely different families and comparing same families. I can see 2.8 to 3.1 or 3.4 60 degrees since they the same family and don't require all new parts. Compare a 3.3 to a 3.8 or a 4.3 90 degree v6.

The 2.8 is a crappy engine if you want to go down go with GM 3.8

The 2.8 wouldnt bolt in, the bellhousing is different. That said, if you had the transmission to go along with the 2.8, its certainly possible. The 4.3 is a far better engine than the 2.8 imo.

Thank You to all who replied, it was just a thought thats all, my dream is to drop a 350 into my blazer but ill wait till the 262 gives out on me first.

Would be interesting, Not sure why you would do this.
