So I have a little predicament here. My 85 150 fried 2 pistons, my guess was it ran too lean from the carb's being gunked up. Well I was bouncing around thinking about rebuilding it myself, boring it out and what not but I got a hold of a 175 powerhead of the same year. I know a lot of the parts are interchangeable but my questions is, would I be able to just swap the 175 powerhead with the 150?

The 175 that year is basically a 150 with larger carbs. It will bolt right in place. Good call.

Exhaust tuner might be different
