    Here's a nice little vid about the various options:

    Especially interesting is his statement about the gears not being compatible with EFI systems because they can create noises that get picked up by the knock sensor. I have to wonder why they don't make timing gears with slanted teeth -- wouldn't that make them quieter?

    Also, when installing a timing belt, I assume you have to install some kind of plate to block off the oil supply to that area?

    That is mostly an old wives tale, run it because you like the sound or just because you want too. 650lb springs are not going to stretch a chain any amount that would matter, and like these guys say the serious guys run a RUBBER belt with valve springs with 4 times the spring pressure over stock.

    Are gear drives stronger than timing chains?

    I just looked up timing belt kits for the 440 on Summit. All are over $1k, with one almost $2k! Why are they so expensive? Just looking at the pictures, you might think it'd cost a couple hundred bucks, maybe $500 max.
