Honest answer I do not know, I wish the Guy I purchase the MID/LU kept the damage Block I was looking forward to use it as a benchmark since the history of my power head is not known. Per the machine shop its stock, but then again he told me the block did not need decking!

All of the V4 loopers have the bridgeport exhaust IIRC, the V-6's are the ones that changed in 88 and then in 92 added the finger ports. The only real change in the V-4's was in 88 going to larger 3.625 bore from the 3.5" bore of earlier years. And remember NYMACK, I'm not that far away and I have a pretty intimate knowledge of the V-4 loopers.

Thanks for the offer, I will let you know if I hit a wall , Did you see my answer in regards to the swap? Let me know if not I will proceed to rip it apart for blasting this weekend, I am very constructive/destructive on the weekend when I am not on call at work..

Ferm my offer still good if not I found a guy with two 25" for sale in Winter Haven

i have a pair of 1990 good 140 counters motors with 25" midsections i bought from BR yrs ago. mine have the 35 amp charging upgrade plus the larger V6 size foot.

I'm gonna have to hold off right now. I would really like to get it, but the wife is wanting a bigger boat now. She wants one where she doesn't have to sit on a bucket to go to the bathroom.

Dam FERM, I wish my wife would say that, I usually get "you are always buying something for that boat and not the house"

Smart girl , Its now a buyers market..

Anyone with blasting experience ? Will this El Cheapo work ?

Crank Clean Up
 

I am not going to use the the Crank from my old power head since it clearly shows a flaw on one of the journals.
I purchase a replacement crank from Ebay not knowing I will pick up an entire engine so I now have two crank on going back on Ebay.
I have since clean up my crank and lube it with 2 stroke oil and wrap it in plastic until I am ready for it.
Here are the before and after photos (crank inserted on the mid-section during the clean up)
Old crank now obsolete see #3 ?
