Are cam gear drives better than a double roller chain? I know that chains do stretch after time, but is a gear drive that much better for a 460 drag engine? Ive raced alot of small block chevys in modifieds on a dirt track, but we ran a claimer rule so no one spent the extra money. I would like to run a gear drive on my 460 but are they really worth the extra money?

Thanx Rick
