[4-speedfastback]

Any one familiar with this cam ? Its a Comp cam 275DEH   .462 In    .482 Ex   gross   .219 In  .235 Ex At .050  lobe separation is 110  my ??'s  are what kind of vac can I expect ? Will it be enough for pwr brakes ?  And I would like a lopey idle .    This is in a 66 383  .030 over and zero decked . With Keith Black flat top pistons w/valve reliefs .  Still don't know what heads to use its between 906 heads or original 516 heads either set will be warmed over slightly . What compression can I expect ?   Its all going in a 66 Charger  4speed and 391 gears  ,  not a drag car just a stout hot rod for weekend cruises .                       Thanks in advance.   Tim L.
