Electronic Ignition Conversion Kit, Fits 8-Cylinder Prestolite with Screw Cap from SIERRA Home -> Engine Systems -> Engine Parts->High-Performance Electronic Ignition Conversion Kits
They sense the current level in the coil and adjust the dwell to maintain peak energy throughout the entire RPM range. Peak current level is reached just prior to spark, so ignition energy is sustained with less heat buildup, which increases the lifespan of the coil and ignition module. Compared to the non-high performance kits, these develop on average three times more available energy between 3000 & 5000 RPM, and nearly double the available plug voltage.

Sierra-Tube-Exhaust from SIERRA Home -> Engine Systems -> Engine Parts
Some larger V-8 engines that create a large amount of back pressure use exhaust tubes rather than bellows. This helps to relieve the excessive pressure and eliminate problems with premature bellows failure. In the past, the exhaust bellows would blow up like a balloon and cause the drive shaft bellows to rub against the yoke and U-joints causing holes in the bellows.
