Updating the Cooling System for LS Power
LS swaps are one of the hottest things going in the automotive aftermarket, and that includes shoehorning them into Corvettes that rolled out of St. Louis thirty or forty years before the LS1 debuted in 1997.

67-69 Tri-Power Carburetor Tuning/Troubleshooting
What is your first impression upon seeing all these carburetors in a row? Sheer terror or wondering why they would do something that crazy? A few of us actually must have them.

1955-1966 Corvette Fuel Pump Rebuild
[ view the Addendum here ] There was a time when a component would fail it would require repair or rebuild. But today we throw it into the appropriate recycle pile. Growing up in the 60s and 70s sometimes makes it difficult to trash anything; today it makes more fiscal sense to buy another one. […]
