hi, i was wondering if anyone knew the stock cam specs for a 1969 4 barrel 351w. i am putting this engine into my 67 fastback. i am using the h.p. ford exhaust manifolds, a performer intake, 600 holley, C90Z stock heads with gasket porting, stock converter and plan to go with 3.89 gears. just wondering whether it would be worth bumping up the cam for these mild mods. was thinking about a comp cams high energy 268H with .456 lift and 218* at .050.
