Ported promax block
200 promax block(painted) ported to 260 specs with all 6 new sleeves at time of build by James Perry. Has exhaust chest work, rod slot notches, and Oiler hole filled. Ran over 100 on an xb2002 loaded to fish with laser fuel injection, wasn’t blown up. Just needs to be honed/washed and built. $800 shipped in the lower 48.

Yep I’m running 1.75 gears though. I was experimenting and ported a 200 FF block myself that I ended up using the internals out of this one to build. My wife ended up giving me hell about it so I had to sell one or the other. That is the ONLY reason for selling it I really didn’t want to. My original plan was to keep it and put crank case injection on it with a horn.
Here’s a picture of the one I’m running now.

I had to end up sending this block to James to have all new sleeves put in it because it was already 30 over and I blew it up on number 6. He did a wild port job on this one and it looks great like always. I’m still breaking it in but it feels really strong so far.

I’m also running a set of James new reeds in this motor and so far they’re the best reeds I’ve ever run and they seal up to the blocks perfectly.

Surprisingly bottom and stayed about the same as the other motor, Probably due to how light the boat is. Yep James is the man!
