What do you guys think about this set up, is it a god solution a bit pricey i think. http://cgi.ebay.com/ebaymotors/460-...ryZ33566QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
Think you can buy very similar Edelbrock brand parts from Summit -- for about that same price. They're supposed to be the ultimate quiet drive, and you can basically eliminate all lash from the drive by fiddling with the idler. I'm a little surprised to see half-round teeth on a timing belt, but that could just be a patent issue of some sort. Most timing belts, the teeth have a more square profile. But you can buy a bunch of premium roller chain drive timing sets for the same money. Seems like a part that doesn't need reinvention.
God point BB the chain is'nt that noisy, and its a lot of money, and if I go for it, it's just for the bragging rightsand i will choose the Edelbrock part over this one for sure Thanks
Unlsess your running a full out race engine I'd save the money for other parts ... Belts are not really meant for street drivers
Well Fomoco it will be a 532 (maybe a 557) with some extra HP 500 i hope, but still not to wild to drive on the street, try to make it with a moderate cam, but i will use some god parts no cheap bad stuff, so it lasts for a while. I had a set up from a builder in the US for a 460 and he guarantied 500 hp on that one, well need the money first to the buildt short block, has big valve D0VE heads and intake, cam, carb and some other stuff. will have 9.8 :1 comp pistons.
Yes, thats what i've got, a brand new set to so the belt would be a waste of Ranchero$$$ Thanks all of you.
One thing a belt will do is eliminate any harmonics from the crank being sent into the cam and valve train. Doubble roller will allow some and a gear drive will allow a lot. Unless you plan on advancing or retarding you cam on a weekly bassis or spending most of your time above 7000 RPM stick with a doubble roller.

I would like to think that if the engineers did their work correctly the cam wouldn't be able to tell the difference, i.e., what kind of drive from crank to cam. I'm guessing that by 'harmonics' we are speaking about momentary crank accelerations due to firing impulses every 90 degrees? But why is the belt better at not transferring those to the cam?
My friend has gear drive in his 351c and if I had the noise of a supercharger in mine, it should for shore be one there to I think its like something is wrong with the engine, so I dont like them or to be exact the noise of them, the function are very god with the direct drive. At this time its the dbl. chain but if I win the lottery it will be the belt.
belt timing good for dyno racing or other forms of racing that you can tear down your engine every season! no good for daily drivers or cruizer. if you don't think so ?try to find a replacement at any store when you traveling! good luck!
I used to love it too, but then I got sick of it. As I result I took it out, and replaced it with a double roller chain and gear setup, and sold the geardrive on ebay. If I knew you liked them Sarah, I would have offered it to you. Dave
I should have described it as vibrations instead of harmonics. Vibration damper to some, harmonic balancer to me. The real advantage of a belt is the ease of cam adjustment.
Ditto that, and ask anyone with a Escort, Prelude, or Sentra that had their timing belt break; which bent the valves, and cracked the head. There used to be a notation in the Gates belt catalog, which indicated 'interference fit' on these and other applications. Translated, it meant no valve reliefs in piston in case belt breaks. JD
