Hi 69conv. Now that's a new idea. Have ample clearance it's just that I spent more on adjustable rockers than a cam would cost. Wouldn't have to take the engine apart. The engine builder built my short block and is doing the dyno.
I wouldn't buy one single part. I'd start with the absolute tune and verify what you already have. Throwing parts and money can lead to driving cost with greater disappointments. If you find a faulty part or a problem, then make a smart purchase.
