I recently just rebuild a 4.3 v6. When i bought the truck the valve covers were not bolted down all the way so i blew all my oil out and shattered a piston. I had it bored .060 over and i have it running now. The only issue i have is that i live in florida its hot already, and now my engine being bored over is cookin. So now i have to find ways to keep it cool. Over all very reliable engines.

I have a 1990 Chevy K/1500 with a 4.3L V6 and i was wondering if i could get as much or close to as much HP as you guys did but with a TBI. And would it be possible to make it smog legal.

I’m building a 4.3 balance shaft motor. the only clearance issue was with the eldebrock intake. But after the head and intake gaskets were on it fit fine. It was close but then again I have my heads ten thousands.

I have a built 4.3 with the 23 degree heads and matching intake from GM. I also have another set of 18 degree head(aluminum)both sets are. The engine was a 2000 and my engine builder kept the balance shaft. in it. a first it had the iron vortec heads and Edelbrock intake. He estimated around 300 HP. Now with the Aluminum head and intake he said I should be around 350HP. I know it runs GREAT!! I have some pics. Special ground cam from Lunati. johneaton699@hotmail.com

I would love it if you guys did a build with TBI. I have a TBI and was looking into a Vortech Supercharger. I love the challenge of making power out of a V6 rather than another V8.

I built a 4.3 about 6 years ago using prebalancer block that came with a four barrel intake and carb. The intake weighed a ton. I wanted to go with vortech heads, so I sourced a late model marine four barrel intake from Chevrolet. That’s how I got a carb on my Vortech heads.
