John, If you freshen up the motor to the right specs and so forth you will be in good shape. Most people work on the wrong end of a Z/28. You can keep the hood closed if you are happy with your rebuild and jack the back of the car up. That is where you have to work on the little 302. Minimum of 4:10's and if you have a chance to put an M20 trans in the car better yet. The key to that motor is the gearing. Even 4:56's would be OK on the street! Good luck! Sam
