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 :D |
Spend the money! If a timing chain breaks it will cost alot of dollars.

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. Ed |
X2 with Ed's info!

Ed and Robert;
What's ya'lls thoughts on the "Pete Jackson" style gear drives for a medium range blown street/strip SBC? |
I have sold a lot of those gear drives in the last year or so never had one come back they have been on street cars
|
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: |
