Well the early Corvette 6's utilized the 911 truck block but a different head. I was able to find a nice truck block in Pa. Geez the Corvette heads are real pricy so using a standard 235 head. I do have the tri carb set up that came with the car. This is going to be a DRIVER not a trailer queen. Love the 6's and why I gravitate to the Stovebolt site. You folks are so helpful in fine tuning these old engines....get everything running right one can just throw any fiberglas boat hull on the frame and have a great time on the road!! Ha
