I have not splashed it with the new motor yet. They are calling for snow this weekend. Man I gotta get my wife to move.

I know that's got to be killing you !! The way I handle things like that is to keep running thru my mind over and over....questions about "Did I do this...remember to do that, etc....so that when you do finally get it in the water you won't end up wasting time focusing stuff !!

But then again...that's half the fun of it !!

BTW...I have that same distributor and wires on both my Vortecs in the 255....no issues since I first set them up 3 years ago. Great job with the lay out and detail...looks professional !!

Thanks. It is supposed to be 37 on sunday, and continue to get warmer all week. I am thinking of going for a cold ride. I also have to get some fresh pics as the engine bay is cleaned up and rigged better. I am really happy with the results. I think I will keep this one longer than I kept my F18.

A point of reference for your speed lol it went 75 before with the 509 I had in the boat with about 525 hp and a worked prop.

Oh someone told me it went 78 with 630hp. I got 572hp with a 25p mirage plus. Splashed it today for the first time with the blower motor. Got it up to 60mph at 4300rpm. Was barely even into boost. Can't wait to let her rip.
