Timing Gear Drive

If its not 400 bucks, its a CAT> (mad dog, thunder chicken, insert distributor name here) I ran a CAT on a 451 and the whine was like a blower, but it was a dual idler Pete Jackson style. Not very good design if you ask me as the floating idler actually rocked between power and coast and there was no room for a line bored motor, If the gears were too close they would turn blue. I got a Milodon myself, have not installed it yet but liked the noise of a gear enough to buy another one for a small block (got it used, a week before I was going to buy a CAT before I shelled out the same for a decent chain and tensioner) its going on a 402 stroker.
