8.5 to 1

Dimond pistons w/ Oliver rods.

what rods and pistons are you running? what did you drop the compression to? I went the K.B. route. right now limited hp due to the rods. 466 rwhp. I met a guy at woodward dream cruise running 520 rwhp on a stock 04 mach motor. 1 yr old stil daily driving and into the boost alot.

o cool

No , it's a o4 Mach 1 block W/ Cobra parts bolted to it.

did you put a 2003 cobra engine in it?

No they don't make a kit for the Mach 1 . The block is from a Mach 1 Everything else is off a Cobra.

whipple makes a supercharger for a mach 1?

hey man does your engine kinda look like a 2003 - 2004 cobra engine?

Yes , the mid range on the 2.3 is much better,looks better to.....lol
