51-423-11 is rated 5.0 out of 5 by 1.
Rated 5 out of 5 by from Great Street/Strip 455 Olds Cam I've used this Cam in my last two engines (468 cu in Olds) and am very happy. I bought the suggested Springs, Retainers, etc (Kit) which is mandatory IMO. I drive my '81 Firebird daily and race it at the local strip regularly. Runs 115mph @ 11.5's in the 1/4 mile and 90+mph @ 7.3's in the 1/8 mile strips. Has a nice lope and just barely "street manners". Glad I bought it.
