Cloyes C-3023X Timing Set 3 degrees advanced?
I have 112,000 miles on a stock 74 454 in my C10 and I'm going to replace the timing set soon before it jumps. A friend suggested using the Cloyes C-3023X double roller with adjustable crank gear and install it 3 degrees advanced.
He said the engine was detuned by GM to meet certain standards, and that using the crank gear to advance it would result in more vacuum, better idle, and better midrange torque.
I have a hard time believing it's possible to get something good for free, and I don't want to do this twice. Is his info correct?
