Question,,, I have a 1997 LS1 and trying to find out how much horse power this motor has is like pulling teeth. I went to the dealer and with the vin no. they found out nothing but the gear ratio is 3.15. All it says is it is a 5.7L, V-8 aluminum block and heads. Does any one know for sure. The dealer suggested I take it and do a dyno on it.

Thank you sir, funny though I had a 69, 350/350 4 speed, 4.11, carbureted and this one just feels like more balls. I am sure it is the fuel injection and all the new tech.

The method of rating HP changed in 1972. You can see this for yourself by comparing 71 and 72 specs for the same engines. The 72 numbers are much lower. In the practical sense, this means that 72-up horses are "stronger" than 71-earlier.

Those who choose an automatic transmission want transportation. Those who choose a manual transmission want to drive.

In 1972 they went to "net" horsepower ratings. The engines were rated with the accessories installed and with the additional drag they imposed on the engines. Hated the way it looked at the time, but understood why. Also, Corvette engine information plaques that appeared on the console did not come with horsepower listed as in previous years. Just omitted it because they seemed less appealing.

Today's base model Kia will probably outrun a vintage Corvette.
