360 budget build questions.

What heads are you running? If your keeping the 2.73 gears, stock converter, and low compression pistons. i would look for a smaller cam with a tight lobe seperation. This will help boost cylinder pressure. Maybe an old isky grind like the 264 megacam on a 104 IC. This cam has low lift so you wont need any special head work or springs. i really doubt that 7.25 will last long though.
