These anniversary ZL1 engines are not built to the original specs as stated in the ad. They have oval port heads, hydraulic roller cams and the compression is not 12 to 1 as the originals were, if memory serves me correctly they are 10 to 1. Other than that they are made of aluminum. I have used new blocks before but we used all the correct specs inside with 074 heads that are generally available.
