Thread: 327 heads/283

The double hump heads and 30-30 cams are old technology, but also very cool technology. Obviously, if your goal was as much hp as you could squeeze out of these engine there are more advanced combinations, but it looks like you realize that and just want something retro. No question that a lot of cars back then ran exactly this setup and sounded great and pulled strong. I knew of a few Chevys back in the 50's and 60's that were very strong performers running this equipment.

As mentioned, you will get very good at adjusting valves. As I remember, some guys ran the lash a little tighter at 28 and felt it ran better there. With the renewed interest in all things traditional these cams and heads are enjoying a new life. I think I remember some hot rod magazine doing a shootout where they compared these old cams to a modern hydraulic cam and the dyno showed throughout the rpm range that the modern cam put out more hp. But you can't modernize cool. Contrary to what some people may think, not every engine or car is put together with max hp as the goal, sometimes image is important too.

Oh, run either a loose converter or a stick setup. I put one of those cams in my 64 chevy and had to bump it into neutral at every red light.
