Which cam?
Ive got a 81 monte carlo, 3:73 rear gear, 29" tall tire, turbo 350 trans, 327c.i. engine bored .040 w/flat-top pistons, de-stroked to 306c.i. ( it hink thats the correct #) pro toplink cnc heads w/2.080 valves. Edelbrock performer RPM intake and Holley 650 double pumper. engine came w/ 270 crane magnum cam. How much larger should I go to be able to take advantage of the engines RPM range. I'm willing to put in a stall converter. Car is primarily street driven. i believe the heads are 64 cc chamber.
