Tell me your thoughts fellas. Motor is being built right now. Just haven`t decided on a cam. I want a BADASS sounding with good power all threw the power band! I want to be able to drive this car daily. Track maybe 8 times ayear. Wife drives the car! Gotta be safe with her, no dieing out!

Get a custom grind, usually cost the same as an off the shelf version and can get more power made specifically for your application

I was thinking the same on a custom grind. Also on the injects, they should be fine. I`m running a dual nozzle TNT wet kit. Thanks, guys!
