1996 Corvette Performance Review

Print Friendly and PDF

The performance figures and specifications listed below were compiled by Forum Member, Stan A (Stan Adelman) of Auto Performance Test Lab located in Atlanta, Georgia. The Corvette Action Center would like to thank Stan for allowing us to post his Performance Review Data here.

Regarding the stock LT4 horsepower numbers, Stan explains:

The LT4 really can vary in Horsepower and torque. Like I said, the average one on the street comes in between 350hp to 360hp. We have tested over 125 LT4 units since 1996 and found that less than 25% of the units come in under 345hp. About 15% come in between 360hp and 375hp. About 10% range between 375hp and 385hp. 2% have been found to hit the very low 390hp range. This is all stock from Bowling Green. Keep in mind that the torque also increases too. One unit came in on the dyno at 392hp/426lbs-ft torque @5850rpm. Very rare but still present out there. This is why there have been reports of LT4s running with or past ZR1-LT5 cars over the years. Basically, the LT4 will out run the LS1 in 75% of all cases.
