351w Volvo + 351w Commander = ?

Hey Group. New to the site in the last week,or so and love it. I must love since my English springer spaniel is named Rudder, and I don't sail. Worked for a friend that had a CC dealership when I was in college. Traveled with one of the first BFN's in 1977. Have owned a 1972 Ski Tique, and numerous 18' SN's, and even a 2001 deluxe. Got out to start a trucking venture. Bought a 79SN in 1999, gutted, had stringers & floor put in, in 2001.
LOVE THIS SITE!!!!!

Now for the meat of the subject. I have a 351W commander showing 661 hrs, known the boat since new, and know the hrs are short.
Have done the tranny. Made an offer for complete Volvo 351w guts and heads (found the 3 marks today / GT40s!!) This engine was a low hour EFI engine in a Four Winds. Had a crack in a water jacket along the cam valley.

Question now can I put all of this in my block, and if so what do y'all think I will end up with?

Hey John, Thanks for the welcome. This site is just what I needed, looks like a great group. Y'know I had another springer named luckey, and my ex made me get rid of him. Gave him to my sister, and they just adored him. Lost him last year, and we all cryed. Rudder is 2, and now my sister has a 9 month old named Dexter. I know what you mean about being close, Rudder is my shadow.

rudderdad, agree with the love for the dogs,have three. English Setter, and two American Pointers.Pointers are required to hunt for their room and board, setter is in retirement,love them dogs.
Now to the meat of your question,why would you do anything to an engine with that amount of hours.If the maint. has been performed properly that moter is good for 12 to 1500 hrs.
If there is no issues,leaks, loss of power or strange noises why buy trouble????????
The GT 40s are a good addition as would be a good intake. Both would be boost in power, and easy on your pocket book.......boat dr

rudderdad,the plenum may be too tall for your cover,some of the older covers were real tight on space.
I would build the long block first,find a good block,transfer all the stuff to that engine . Then do a pan and elect. swap when you pull the old motor. That way you have a fresh motor that should last a long time.
Maybe a good time for the cam and intake upgrade,and stay with the carb setup,simple really is BETTER.........boat dr
