525 EFI Valve Springs, Simple Question
#41
It's kind of funny that a lot of the people that will gleefully swing from the Mercury Engineer coin purse are the same people that would criticize a home built 502 with aftermarket heads, roller cam, EFI, and header exhaust system for "only" making 525 horsepower.

Man I thought I over paid for the ones I bought off ebay $10. That have been on 3 different motors. Off and on I don't know how many times adjusting valves. Never a drop of oil out of them. But I guess Mercury does know how to best pick money out of your pocket.
