They came in some Chevy IIs. I wouldn't want one in a car heaver than that but a little '62 two door post with a built 4 cylinder would be fun. Probably not much savings in the build but different. Start with a 181 Mercruiser and you are already at 140 HP.
I put the 153 in my 47 CJ2A Jeep. The engine was carefully rebuilt ;.023 shim gasket to get quench at .043....steel tube header, modified distributor advance and rejetted stock carb.
The Jeep weighs about 2200 pounds, stock 5.13 gears, 4x4 and 3 speed. The engine runs great and the performance is better than the original 60 HP Red Devil flattie but just still adequate at best.
Maybe in a 2000 pound car with a 5 speed , hotter cam, more compression and carb you might have something until the next punk in a old 4 cylinder Interga blows ya off
