gears or timing chains
need to know if the milodon timing gears are reliable and good for
drag racing or should i just go with a billet true rolling tiiming piece.
the gears cost more but if they realy work well that would be the
choice, i don't want to go with a belt, for some reason i don't like
the idea that the belt will start to crack just like a serpentine belt
thanx for looking and helping out

but you know I think about one small gear taking the punishiment
when a dbl roller chain is a unit of strenght, mmmm don't know,
and a dbl gear rotating that fast wonders if it would bind one day
or just chip a little at a time. im thinking of going with the milodon
system with 3 gears. well see
thanx :wink:

I can agre with previous poster except the same possibly applies to belts too. Gears do trasmit crank harmonics more into the cam.
I have built literally hundreds of engines over my lifetime. I have no idea how many and have never had a Cloyes True Roller Double Roller chain to break. I have engines in all horsepower ranges using the best Cloyes. Low to medium spring pressure engine I like the Hex-A-Just. It is much easier and is quicker to degree in. IN the high horsepowered and big strong spring pressure engine I like to use only the Cloyes Quik-Adjust which uses 6 perimter bolts in the two piece Billet Cam Gear. I have those on engines over 2,000 hp and with 460 # seat and over 1,250 lbs open pressures. No issues.
Do use Gear drives with engines using Roots styloe blowers with blower drives on front.
If it is a spring pressure lower than 225# seat I suggest the Cloyes Hex-Adjust. iF it is higer I suggest the Cloyes Quick-Adjust for more money. It is really nice.

you know when i was going for the timing chain the
Cloyes Quik-Adjust billet gears is the one i was looking at
i just think that the chain has more of a grip than a single
gear high in hp, need to realy lool cause if the chain
can go a good season with around 800hp than for the
price is right :wink:

The Jesel or C.V. products belt drives will run for several thousand race miles without a belt change and are the best choice if the budget allows. Bill
