One of my favorite motors out of my shop.....509 Chevy...420 B&M...Superchiller...Brodix 2+ by Yelvi....2 Nicherson 980 CFM 4150 flange Holley's...This thing will run low 9's at 118mph with 10# boost in a 780# Mirage jet hull(one of my old drag boats).It sounds like a fueler idling and except for the fuelers,it's probably the loudest boat out there.I guess I should lock out the advance so it won't surge so hard.
Garry That rig is one of my favorites also, cause it leaves like a V-Drive, and runs like a bat out of hell.
