Ways To Beef The 4.3

[jro909]

my buddy(not mine i retired my 4.3 almost a decade ago lol) has a 4.3 in a ECSB and its sort of a dog(obviously) and i'm trying to research some cheap ways to get a little extra out of it, its not a long term truck and not wanting to throw thousands at it..

A 4.3 is never going to make enough power for a fullsize truck.

 

The only thing you can really do, is give it a better mechanical advantage. What gears are in the truck now?

buy a 5.3. I never understood the 4.3. A friend has a 4.3 and always rags on me for having a bigger motor and says there is no need for it. All I have to say is its a truck and I bought it because its a truck, I need a truck for work, and Im going to use it like a truck. He works in a cubicle and has never hauled a single thing in the bed.

Gears are where its at for the 4.3L. Get a set of 4.10's in there and watch the gas gauge fly.

 

Tune and gears man...That's all I would do to it....everything else is a waste of money on that motor.

 

 

Although.....probably the cheapest thing he can do is trade it in for a V8 truck, If you haven't noticed, GMT-800's are not exactly expensive.

Try adding a B&M Torque Converter, Traveler Series to your truck. I added one of those to my V-6 C1500 and it made a noticeable difference. However, if your looking for your V6 truck to put you in a head lock, you'll need to go well beyond that. My suggestion, use the truck as a truck, and purchase another vehicle for the speed. That is what I did.

Our company truck ecsb has the 4.3 in it. Does its job for use, hauls more than its fair share in the bed but never tows. We have had 5000# in the bed! So far the leak link has been the 4L60, not the 4.3, however its a dog.
