How can I get more horsepower to my 93 C4?
The LT1 version costs approximately $35 dollars and you reuse the old sensor. This is a plug in modification after you drill a 7/8 inch hole in the air cleaner shroud and does slightly increase horsepower. There is a reported 3-5 horsepower increase but there are no published dyno runs to back this up.
What was the transmission on the Chevy Corvette C4?
GM tried to cover this by adding a new transmission known as the Doug Nash 4+3. But it was as weird as the name suggests, and it nearly ruined the car for the first six years. The Doug Nash 4+3 was a four-speed manual with an automatic overdrive on the top three gears.
How much torque does a 89 C4 have?
I did everything except the mufflers on my ’89 C4 and calculate that the net HP is now between 290 and 300 net (the stock engine is 245 net) and the torque is now around 370 ft/pounds versus a stock 340 ft/pounds. This means my car has between 45 and 55 less HP than the C5 but has 20 ft/pounds more torque.
What was the first year the C4 Corvette was made?
Keeping the 4+3 transmission right where it was with upgraded internals to improve its quality, by 1987 GM also gave its V8 roller hydraulic lifters for 245 horsepower, only to continue with a revised suspension system for 1988. All these small improvements led to the 1989 Corvette, the first C4 truly worthy of its badge.

When did the 3 speed manual transmission end?
The 3-speed lingered around during most of the 1970s in smaller numbers than the 1960s and by 1980 most 3-speed manuals were gone. The 4-speed eventually replaced it and was then replaced by the 5-speed. Today not many cars are equipped with manual transmissions.
