Building a blown 540 and dropped the block off last weekend one of the things i hadnt decided on was using a roller chain or a jesel belt drive. My motor shop guy told me i have a week or 2 ta decide since the crank and rods are still on order so he wont need a deff. answer till he gets to that point but i told him i will probaly go with the jesel drive.

the price difference is about $400 give or take a few $$$ but from what he said the jesel is far better for this type of motor.

I have never had anything except for a timing chain(never even had a gear drive) so i admit i dont have any "real knoledge" of a jesel belt drive so am i "right" by saying i want it? I know it supposedly wont transmit any harmonics like a chain will but are there any other benifits? or for that matter any drawbacks?
