I'm starting final assembly of 428CJ for a Superformance Cobra due in 5 weeks and looking back over my info may have missed something.. This car has power brakes and the cam i have installed is listed in their catalog as marginal for vacuum . I talked to cam rep. and they thought " should be OK " .... I don't want to have to change cam right after I install.. my engine is 428CJ 10.1-1 Edel alum. heads Alum flywheel 2x4 med. rise 2-550 holleys [ from past experience 2x4 less vacuum] cam in question is Comp. Cams 280H [230 @ .050 - .530 lift] Any experience with similar combination or this problem??? Ive recieved mixed opinions from my local group...THANKS Steve McD.
