Jer,, how close is your engine to being done? Where are the pics? Boat engines are a different breed of engine than any other. Drag engines are loaded quite differently and for a much shorter time than a boat engine. When you think about it the stresses on a boat eng are phenominal(I know big word)and they are constantly loaded and unloaded just cruising across a lake. Closest I can think of is running Baja in a 4wd truck, minus the dust. Most of my experience machining was drags,some score and a little indy. Got to see some funky experiments, some worked, some didn't. If you learn from it then okiedokie. I did learn to ask lots of questions and if 10 answers were one way and 2 the other, then maybe the 10 were right. If any of us knew it all we wouldn't be on the boards, we'd be busy and filthy rich. do they make a Merlin flathead Rambler 6? idea
