It ran great and sounded good also. No problems.

Crazyhorse ,

how long does it take to break in a new cam.

i picked up my broke 502 today and the cam is in bad shape too.

We like to run the engine at no less than 1500 rpm for at least 20 minutes. Then we shut it off to change the oil and filter, followed by a run of 15-20 minutes. At the end of the second run the idle is set at 800 rpm. Any idea what you want to do for a replacement cam for the 502?

ive got twins and the other 502 runs fine.
both motors are "stock" so im going to put a stock cam back in it.
i dont really have a choice unless i want to spend even more money

That's true. What hp is your 502? Just wondering if Federal Mogul offers your camshaft.

they only have 390 hp but its enough to get me 80 mph in a 28 footer

the previous owner installed them.

they are basically big truck motors.
