Hey Rob,
I know a guy that may have a left over 420HP/8.2GSI Volvo Penta test engine for like 7K.
It is a 502Mag with an AZ Speed EFI and GM wiring with MFEI-3 ECM.
You could rig the boat with a Konrad drive and this engine. Then when you get her back to Cal strip the engine of it accessories, wiring, ECM, and use every thing on your 572.
A 502 longblock is worth 3-4K and the AZ Speed Intake is worth $$ too.

Dont Waste your Money Just Put The drive On And The Boat will Be Pre Rigged For Your Big Motor And Just Buy Merc Assys For It And Your Good To Go ..Thats What I Did For My Boat The Parts Are Not That Much Money ..I Have All The Part #s For What You Are Gunna Do And This way You Can Have Coenhead Get Them For You

Lightspeed knows best...
And I would bet you still have plenty of time to get your engine to NY if you don't mind paying the shipping.

Damn Pat stop being right all the time....

Yeah thats what I found out this moring that it would have no value as a donor so now its a question of race to get the real motor done and hope all the parts come together when they say they will or spend 12k on a motor that I'm only going to get half value for in 6 months? I need to find a better hobbie.

I've learned a lot reading on this sight and piecing together stuff from used parts I've bought...

If you are still entertaining the thought of a donor/test engine, one of these would be a much better value.

Pat is that a Volvo ??? 425 hp ??

Yes it is... we sell all the volvo stuff too. They used to make motors up to 600 hp. Not shure if they still do though...

Rob,
Finally got the glass over the tank and . Did a few hours grinding to make everything look nice for gelcoating. Plus we flipped your deck over. Here are the first pics. The deck next to yours is the 24' deck we pulled out today.

The engine in the picture is a 2000 or 2001 model year Volvo Penta 420HP/8.2GSi.
Basically it is Volvo's version of the 502MagMPI. The main difference between the Merc and Volvo is the MPI Intake.
Merc used their own castings, Volvo used AZ Speed.
Gee I wonder which is better?
Gary, if you don't catch my sarcasm, The AZ Speed Volvo used is the same Merc uses on the 525...

Pat I would just like to see Rob's new bottom run some speed trials in a known motor. Volvo, Merc, ETC......... and we all know the 425 #s.
