Someone on eBay was trying to get 600 or 700$ for just the cylinder. I have no clue what they are worth but I know there are at least 3 guys on pwctoday looking for one. I have one too that I am looking foreward to trying out this summer if nobody steps up and buys it. They are supposed to run pretty good and are pretty rare. I read somewhere that back in the day they were 2500$ new
I had that same motor back in the early 2000’s with dual blue sudco 38’s and a ocean pro head. I dont remember if the head was pp spacing or SX spacing but you need to ditch that stock head for a aftermarket one. Westcoast used to make on with removable domes so you could change the compression. I was running 195 compression with AV gas.
All i can say is that setup was one of the hardest pulling/fastest setups i ever built! Running a straight 15 skat in a 550 pump it was like a light switch.....on or off! Gave me tunnel vision! I think i was running a PJS full pipe, manifold and head pipe.
If i was you I’d hold on to that! Get the parts you need over time and build it! You wont regret it!
