i think i really caught the bug.. since i put on the 3.6 and my tune an not hitting 13.9999's at the track, i bought a 3.5 pulley and a.. oh no...... a 3.4. i know i wont be to bad with the 3.5 i have no kr at all, blips at part throttle an none throughout WOT, im gonna scan when i do my 3.5 and go from there.. but what do you really think of the 3.4, stay away without rocker or cam or other flow work such as heads? or Will i be fine if i install my water meth kit an get retuned/tweaked..

also this is just to keep me entertained until my motor is done being built.. block is about done.. its .20 over with hypertectic pistons, i had to have the crank cut an polished an i got a VS cam an the #90 springs, i also had the lim and supercharger port and polished

Gonna have to scan and see what happens. I didn't step down to a 3.4 on my 04 until I rockered it. Couldn't run it knock free without em. Now I have an SSIC and run a 3.2 and run knock free with 20* of timing

I'd be careful scan for KR def! I'm scared to throw on a 3.5 with my setup which is like exact motor mods as you. A 3.4 I think would require valvetrain mod or intercooler at the very least. Prove me wrong though as I know some cars come with more KR.

yea i tryed the 3.5 and was getting 2-3* of kr throughout a wot pull, so i just put the 3.6 back on with no kr at all, it wierd that tiny differance between the two it changes so much. so for now ill just run the 3.6 till i get my water meth on... and ill put the 3.4 on my motor build an not this one..
