BTW- Nope, I don't think so. That's something easily searched out tho. You'll have more compression and actually,- you'll have the most powerful engine made with OEM parts for that generation of truck. More than the original PI motors anyway. - Excluding the lightning/SVT.

Before tuning it, I'd make it a little worth while. Like say LT's and intake.

 

LOL. The older I get, the more conservative my driving style. Plus it's really nice on your insurance when you don't have any speeding tickets in 8+ years. That coupled with running nothing but 93 in her exudes a lil more self control with my right foot. At one time, I was much like [MENTION=146035]Jackedup00[/MENTION]. Tore more cars up than I can count. It's when you start footing the repair bill that you gain a whole new perspective.

 

I've paid every repair bill I've gotten and I just now learned my lesson lol.

 

Right, I bet his vehicles run and hide as soon as they hear that key jingle.

 

My truck ain't running nowhere

 

And that's exactly why I included you in my statement my friend. You live and you learn. The more you have invested in something, the better care you take of it.

Now that's just being brash jbrew. I bet you destroyed a few things in your early years! LOL

 

Don't get me wrong,I'll still tear **** up but it will be in a truck I buy or build that I don't care about. If it breaks,oh well I'll find the part at a junkyard later.

 

Can I use 01 4.6 lower with tuning valve for my pi head swap

 

Its 99 pi upper with 01 heads on my npi bottom end

 

Thats because you broke its leg, heart and a lung
