Re: 350 for torque/mileage
268H is a cam grind profile. Good choice for truck or RV types.
I prefer the XE250H from Comp Cams for a bit lower RPM torque. It seems to work especially well if you have lower compression, stock heads, headers and want to cruise in the 1800-2500 RPM range. Below are links to dyno sheets for SBC (with DART heads).
