Im getting ready to replace a timming chain in my merc 454. can I use a standard tuck chain and gears?
Quicksilver wants a fortune for them.
also is a double roller a better option?

So far as chain and gears the GM truck/car is the same as Merc. As for double roller, I wouldn't do it unless your going to build some big power and even then I might not do it.
the comp cams 7101 double roller timing chain cover clears the Gen VI housing without a problem and has needle thrust bearing for the cam surface.
and it has 8 positions for setting timing depending on the cam grind you want to run
I would also drill a 0.030" orifice hole on the cam bearing galley plug to act as a squirter on the back of your timing chain. this will keep the timing set lasting longer than the rest of the motor
