im needing opinions on what cam to buy for my 305 TPI car.its a MAF car and I have a stock engine. I don't race it ,merely drive it. im looking for more lift and duration WITHOUT hurting the excellent MPGs im now getting. im not looking for wild pie in the sky . I would just like to maximize my 305s potential.any one with experience on this subject??

 

Can try a smaller comp xe. Should run ok on stock tune but would run best with tuning. Something like the xr258hr. its similar duration to the stock L98 but much more aggressive lobe and higher lift. run with a beehive spring kit and it should clear stock heads for that lift just fine.

Just about any cam needs some tuning to make it worth the effort. Alittle step up would be xr264hr. 212/218, i would think this would be a nice runner with alittle ecm tweaking. Should run ok as is tho

 

Crane and Comp cams offer a "compu-cam" selection of camshafts for computer controlled vehicles.

 

A vid i threw together a long time ago about camshafts and what to look out for:
