How much horse power does a 1984 Chevy Corvette have?

Answer 1

Unfortunately late seventies and early eighties were bad years for performance Corvettes. The SMOG police (Federal Government) were forcing American Manufacturers to kill performance with emision control standards, which were required before American Manufacturers were ready to cope with new engine designs.

The Stock 1984 C4 Corvette had a L98 engine which produced 250 HP. It wasn't until 1992, that Chevy introduced the LT1 350, which had 330 HP.

In 1990, GM also released the ZR-1 Corvette, with the LT5 engine and this one was a good performer. It had 32 values 4 overhead cams (2 on each side) and produced 375 HP. In 1993, Chevy changed the cylinder heads on the LT5 which netted in 405 HP.

The L98's exhaust system robbed a lot of the power from the 350 CI motors. Changing the L98 Vette's exhaust to headers will greatly increase the power. Add a new High Flow manifold and worked heads and you can get 330 HP relatively easy. Add a good cam and you should be able to make somewhere around 350 HP at the crank. Rear Wheel HP around 300 HP.

If you really want to get aggressive, swap the L98 for a LS1-LS6 motor. That will give you around 370-440 HP with new exhaust. I would not spend a whole lot on the L98 Motor. However, try header and something like Magnaflow mufflers first if you are on a budget. That is the most economical way to get 25% more HP from the L98. The stock exhaust ruined this motors HP. Torque specs were pretty good on these motors as the heads and intakes were tuned for torque, not HP.
