The motors were just put together an Innovation, and I am not impessed with the final hp(but that is not Innovation Marine's fault); my father ordered these motors and cams (short blocks before he passed away) -- 540's with a mild compression (doesn't help make hp, but is cost effective for fuel) and a mild cam with Gil exhaust and silent choice restrict how big a cam that can be utilized to gain more hp.

I am really suprised that there is not an aftermarket plenum with bigger cfm available for this application. I am not against throwing a Dart intake and an 1150 Dominator on top, but for now it will stay an EFI boat.
