Chain or Belt driven what is better?

From what I've been told, a gear drive on our particular engine would not be a good idea. The distance from the cam to crank gear is too great for the gear drive to run reliably in the space provided. I think they did exist for the older LA engines, but I don't know how reliable they were.
btw, that angle or distance from the cam to crank is what also makes for reliable and longer stroker motor possibilities.

Absolutely no reason to go to a gear drive, get a good double roller and call it good.

I disagree with the first part (quieter, a little more precise long-term), and totally agree with the second part.

No knock sensor, gear drives are louder than belt, or chain.... (unless it is specifically designated as a "quiet" drive.... otherwise, that blower whine is present). They are indeed more accurate though, and don't suffer from stretch at all..... 
Not sure if the cam/crank spacing is the same from LA to Magnum blocks though..... I know the lifter angle is different.... but, never really got down to any other nits on that topic.

I was thinking of my International 392, which has helical timing gears. For the (straight-cut) gears made for Dodge engines, you're absolutely correct.
This cracks me up - from the Summit catalog:
"Machined for that distinctive gear drive "noise" ".
Oh yeah, give me that good old "five-speed backing up at 30 MPH" sound for my V-8; just can't get enough of that sound.

I just looked at those in my Summit catalog, and it says "NOTE: Will not work on computer-controlled vehicles with knock sensors". I that us they're talking about? Do we have knock sensors per se?

Drop 120 for a timing chain and another 40 on a tensioner and spend the left over money on gas.
