Hey, that's a good idea Ohio-Dan to run a mild solid tappet cam on your little 305. You can get more power out of the smaller engine with a more aggressive profile than a hydraulic without sacrificing too much bottom end torque. I was wrestling with the idea of "warming over" my 305 in my 79 Camaro since I already have a stout 350 in my 78 Camaro. I guess the only drawbacks are noise and some extra maintenance but heck my slant six had solids in it and it went the last 100,00 miles of it's life without checking lash!
I think my 305 is going to get "recycled" with a solid cam but I doubt it will go 160,000 miles without even removing the valve covers before the next re-build like I got away with this time LOL.
