 The Vortec-style E-Tec heads...  The Vortec-style E-Tec heads and intake manifold use only 8 intake mounting bolts, instead of the normal 12. Note that they also go in straight up and down, not angled like stock GM bolts. They're also much easier to install. |  The Performance Distributors...  The Performance Distributors HEI is a mini power plant in itself, capable of providing enough electricity to ignite the primary boosters of the space shuttle! |  When we tested the Edelbrock...  When we tested the Edelbrock Q-Jet carb we had to bolt on this adapter plate. It's an easy task and made the carb tests a little more interesting. |
Testing The 'BotAfter it was built, the dyno staff at Speed-O-Motive bolted the 'Bot onto their DTS engine dyno for a full day's flogging. It turned out that it didn't take a whole day to see that this thing was like a gorilla. Basically, everything worked great right out of the box. We set the HEI at 36 degrees total advance and made sure fuel flow was at a steady 6 psi. The dyno pulls we made with each carb showed promising results across the board. Although peak power figures were slightly lower than what Edelbrock's 383 made, our engine was almost 30 ci smaller, so we knew we had a winner here.
The same set of 1 3/4-inch...
The same set of 1 3/4-inch headers were used in all tests. 1 5/8-inch headers may have made a little more torque, but we didn't have a set to try out.
