Okay besides saying "put a 350 in it"...what could I do to a 4.3, 93 GMC Sierra, IN FRAME, to give it some more punch. I remember way back when I had a 229 CID Chevy Monza and I bought an "advance curve kit" for $12 for it at Harry's Hot Rod Shop". Wow...that $12.00 and 30 minutes of my time made that little dude launch.

 

Give it a good tune up with quality parts, consider a tuner chip that will change up the shift points...just putting a K&N filter it will DO NOTHING except make your wallet lite... the air coming in has to equally be able to go out... a ported and polished intake and headers... be sure to do the engine mods before having the turned chip done so that they can all be tweaked to work together...

 

What towing problems have people had?

 

This truck can handle anything
