There's GM HEI's on Ebay for Way cheaper than the cost of the pertronix and run better imop. I got mine for $65 shipped and it ran perfectly. If you like the stock style dizzy than the pertronix will be the way to go, but the HEI's on ebay are hard to beat for the price. You just type in 292 chevy 6 hei and a ton will come up.
