273 Commando

Thanks for all the comments! After reading them, visiting with a few more people, and doing a little more research I have made a decision. As mentioned before the car is original, matching numbers. In wanting to keep the car as close to original as possible, including the drive train, I have decided to retain the solid set-up. Many have suggested the Isky E 4 cam will work well. Thanks for your suggestions, I think that's the cam I will go with. Will keep ya'll posted.
