For about $100 or less a new stock cam and lifters can be had. I would at least do that and have a fresh cam with no wear and new lifters. Not a whole lot more gets a comp cams 240 or 252. If I were going to run either engine that is the least I would do. The stock 250 cam (either one) is bigger than the stock 230 cam. Some people have had good luck with the Mercruser cam but I don't know how much they cost. Just a thought. Jay 6155
Thanks, I'll replace the CAM. Going all in with pistons and lump port head. I've decided to look at this engine for parts; i'll use the crankshaft for certain and the block if the one I pull out of the car is shot. I'll give a few more details on the other thread. It's a shame that I don't have an application for a stock 250. I'd buy a new crank if somebody could use this engine. I'll suggest that in the other thread.
