Firewall Mayhem
Crankshaft trigger mechanisms have been used in racing applications for a considerable length of time. In truth, they’ve actually been in service for decades. It’s a simple known fact that one of the best ways to improve engine performance is to ensure that the ignition timing is stable. That’s the whole purpose behind such a system, and that’s why racers regularly use them.

CURE FOR A CLUNKER
If you are towing your rig with a ’99-’06 General Motors truck, or a Chevy or GMC vehicle, there’s a good chance you have experienced a strange clunking noise when making slow turns. The clunking noise seems to originate from within the steering column, and some owners can actually feel a small vibration in conjunction with the clunking. If you have encountered this problem, it’s not your imagination, as there appears to be a unique conundrum associated with Chevy and GMC pickups, and their corresponding SUVs.

Okay, okay! After listening to oh so many of you, we are providing information you have been requesting, and perhaps searching for, for some time. That information is carburetor data, information that we used to take for granted but that has become more and more difficult to find of late. It seems that much of this data for numerous models and years has somehow slipped through the cracks. This could be mostly due to the age of the information, plus the fact that many of those applications are more rare today. We suppose there are numerous other reasons as to why this information has virtually dried up, so we present a basic listing here for the correct carburetor number for the respective engine application.
Camaro and Chevelle data is generally more readily available than, say, that of the late-’50s and early-’60s, so this is especially relevant for big-car owners. Luckily for those with such interests, over the years we have managed to assemble this difficult-to-obtain information by rubbing elbows with those who had such information. Figuring that many of you would be searching for such information over time, we compiled the data for a later date. It seems there wasn’t much need for it at the time, as this information was no longer relevant because it was “past the 10-year rule,” or pertained to years no longer allowed in drag race competition.
We hope you will bookmark this listing, and perhaps print it out and share it to keep it as a handy reference guide (in your glove compartment) to use at the swap meets you attend to help confirm the correctness of a carburetor or fuel injection on any ’58 -’61 Chevrolet or Corvette.
