Thoughts on a 225 rebuild

I would suggest you contact Doug Dutra ('Doctor Dodge') over on the www. slantsix.org forum about some new moderate lift/moderate duration cam grinds that make more torque (and thus mid-range HP) with a 1 BBL or 2 BBL carb. I am about to install a new one for the 1 BBL in a fresh engine rebuild; the 2 BBL version should breathe a bit more at mid to higher RPM's to match up with the better flow of the Super Six. These will work with stock or replacement stock springs (like the VS510's), and stock valve trains.
