What are the pros and cons of using gear drives vs using timing chains, besides the price difference. I'm getting ready to build up a '68 J-code 302 for my '46 Ford truck and was wondering what would be a better choice for this engine.------------------

Gear drives sound like you're out of power steering fluid. Cool at first, but you'll be changing it out for a chain drive w/i a month.  The best is a belt drive.  SteveW

What about a single idler gear drive? I've never heard one before?You'll get better timing acuracy with the gears, they are harsher on the valvetrain and they do sound aweful. Belt drives transmit less harmonics but are spendy. I "think" the best would be a dual gear setup with a reverse rotation cam....I don't even think they make them for SBF's though?

Thanks guys, this was the kind of input I was looking for. I think I'll use the timing chain for the 302.  ------------------
