X2...the fact that these are LS based motors is very exciting!! Hopefully the aftermarket picks up on these new Motors...a turbo kit on SCSB 4x4 4.3 would be sick

In a RCSB or LB truck, I would imagine they would run pretty decent. The older 4.3L's were the only decent entry-level V6 option available for a full-size truck, in my opinion. It was getting long in the tooth by the time the GMT800 debuted and was begging for a reboot for the GMT900s debut.

If I were to buy one, It would have to be 4WD RCSB W/T, 2/3 drop, single turbo setup, focused on lightweight full size truck performance. I think that combination would make for a great handling, decently quick truck at a very competitive price.

The 4.3 in a RCSB should run pretty good. They seem to make the same power that the previous 4.8's made. I'm sure it wont be long til we see one.

We have a '11 RCSB WT with the 4.3L. It's actually got decent power and pick up. I'm sure with a few bolt-ons it would be pretty quick.

They are refering to the NEW 4.3, it's completely different.

My company truck is a 2014 GMC Sierra 1500 CC/SB 4wd with the 4.3L V6 & 6spd auto. I am impressed with the little engine. I had a 1993 Chevy K1500 reg cab long bed 4wd with the old 4.3L V6 & 4L60E. The old 4.3 was a dog in the full-size trucks. It would kick out of OD all the time. The new 4.3 is impressive. It definitely needs a tune! It has a delay when pressing the gas pedal.

Glad to hear some first hand impressions, especially in a CCSB!!

I really do like the idea of making a modern-day, full size Syclone. All it needs is a turbo, order it in 4WD RCSB (I'd probably run RCLB because I'm weird) and a 2/4 or 3/5 drop.

Just got a 2014 4.3 rcsb 2wd, it's a company truck. From a stop it feels almost as fast as a stock NBS 5.3 rcsb.

The little V6 really really surprised me, it's fast for what it is and mileage is great. It needs a tune asap as mentioned, and I'm sure 3.73 gears shoud be an improvement over the stock 3.23 gears.
