Does anyone know of a physical diference between an L99 & an LT1 engine without tearing down the engine?
Thanks for your help.

On the drivers side of the block an LT1 will say 327 an L99 says 588 behind the drivers side head either 4300 or 5700 will be cast in as well take a guess at which is which.
