There are several things that I know about: 1)external fuel pump,
2) I will probably eliminate the water pump, 3) there
are marine versions of the carbs out there, but I've
always used an automotive version, 4) I have
a high-torque, low-power starter that I will use,
5) I believe they make a stainless steel head
gasket for salt water use, but I don't run
in salt water enough to worry about it, 6) I will
need a 502 flywheel, since my 454 one won't work.
: : : Was wondering if anyone has any experience dropping a
: : : 502/440HP in a boat. I have a deep-V with a built-up
: : : 454 (HP unknown) now, and want to move to a "stock"
: : : engine. Recommendations on stock vs modified 502s
: : : are welcome..
: : Thats how the 502 engine started out. It was a marine engine
: : The new Gen 6 502 has 450 hp with automotive exhaust. We've sold

: To convert a 502 for marine use what external parts are needed. Thermostat, cover etc.?
