Most Limited Late Model-level classes require a stock-style distributor. For Chevrolets, this means an HEI that includes the coil inside the distributor cap. We're using a high-power race HEI from Moroso that should provide plenty of spark well in excess of 8,000 rpm-where stock HEI distributors just can't keep up. We're also using Moroso's plug wires, which are already cut to the correct length and marked one through eight to make everything just a bit easier. By the way, the standard firing order for a Chevy small-block is 1, 8, 4, 3, 6, 5, 7, and 2.
