gear drive?
 

why can you not run a gear drive with a solid roller cam?

Who says you can't

I do and 3 others, We all run the Milodons. :D Its actually only 1 of a few things We can agree on. :shock:

thanks for the replys guys. ive just heard you couldnt but i didnt understand why.

I run a Donovan gear drive with a solid roller. A quality gear drive or belt is the only way to ensure accurate cam timing with long life.

i don't think i would use a belt drive system even if they gave it to me- :shock:
gear drive-- precision all the way 8)

WHY?

i just don't trust belts- ive seen too many (high dollar good belts) tear,crack,dryrot- ect...
your gear drive will ware a lil but at least it won't tear, or brake ect...

The gear drives usually are in blown applications. That I know off. The gear drives transfer alot of harmonics through the motor. The chain isnt so bad but the belt drive is FAR better in that area. Easy cam adj. I run a Jesel Belt and nothing else. My boss jeff on his Chevy Hemi has a jesel belt drive and on his 5 blower motors those are all gear drive.

Replace the belt every season!!

O K, just so I understand this. Its O K to have harmonics in a blown engine but not a unblown? Does the cam drive know or care if it has a blower up top. My Buddies 565 broke 2 high dollar chain sets with less than 75 passes both times. Belt drive kept leaking oil. Yes, 2 of the blown cars We know run the Milodons, so that was good enough for Us and no issues. He does put down a lot more passes than me, but I feel more comfortable with the gears. Replacing 4 chains, You can have a reliable gear drive for the same money. Popping a chain aint cheap, either. :?

The chain is transmitting the same harmonics a gear drive is.

Chains/Gear drives have been used a hell of a lot longer than belts.

The harmonics of a chain/gear are going to be absorbed by the balancer, right along with the crank harmonics.

If it's a blown motor, the blower belt absorbs the harmonics.

I think a lot of this is more wives tails than truth. If the harmonics were such an issue, you'd see cam bearings trashed on a regular basis.

So then what is so bad about a jesel belt drive then??????

they cost 800 - 1000 bucks. :P
