I have a 97 1500 5.3 swapped. Planning on doing the on3 single kit. Looking for 600-650 rwhp. Has anyone used this kit? What modifications are needed to make it work on the older truck?

thanks!

 

There are a lot of reviews here, and elsewhere on the internet, of on3's kit and the modifications it needs.

You'd be better off talking to Trick or KB Racing and using one of their kits.

 

I have one of these kits on my truck . And if I was going to do it again I would definitely go with a more expensive kit. The bov was junk and never sealed even after 2 different springs so I ditched the gate and bov for precision and that was a extra 700 .. Downpipe vband location also blows so plan on getting rid of that also
