Should i drop to a 3.0 on a Gen V or a 3.2?

[jayroca]

My Mods:
XPZ Cam w/Pushrods
Stg 2 or 3 Heads w/130# Springs
Ported Lim
Gen V w/ 3.4 pulley
N* LQ4
Intake
60# Injectors w/Fpr and Walboro Fuel Pump
Zzp Tune for Mods

I currently have NO KNOCK Would i be safe to run a 3.0 on the Gen V? Or try a 3.2? Im always scanning though.. Thanks!!!

So what will you do when you encounter KR? You can drop, but without the ability to change the tune, you'll pulley back up with Knock. So if you have no knock, I'd say enjoy the ride!

Pretty much sums it up. Most throw on a small pulley and tune around it to make it work

zzp tunes are rich so you could probly get away with a 3.2 but with the mods a 3.0-3.1 is doable with a real tune. If your spending money on those mods get a real tune, you wont believe what your losing. With that being said gauge your pulley around being able to run like 17-18 * timing with 11.7-12:1 afr knock free.

pulleys are easy to resale, I would go down a little at a time and resale the one you know you don't need and wont use anymore. Its always better to have more pulleys than less.

Cool i will try and 3.2... 3.0 to max out on pump gas... If im knock free... 2.8 for the grand finale... On e85 and a dyno tune
