Comp cams 12-432-8 ex282HR SBC

Summit RacingSummit Racing Verified Purchase

Installed the EX282HR roller cam in my 71 Z-28. Had a performance flat tappet cam, the added power is amazing!!The 282HR has more lift & duration, rev's faster; and generates more vacuum at idle!! And the sound is awesome! highly recommended!
