Re: Mercruiser 181 4 banger
The old 120 and 140 mercruiser motors were based off the Chevy II 153 engine. When the supply of those ran out we were using a mid 80's motor. There were some differences but they were close. We had to drill the front of the block for the mount. The 140 had a head with bigger ports than the 120. They were also 4" bore if I remember correctly. I like your idea on the strombergs.
