I agree with the general consensus of this topic. The 484 & 509 MP cams can be made to run fast, reliabe & consistent. Maybe not FASTEST, but they're great proven bang for the buck.

Just my opinion, but some need to have the latest and greatest technology for whatever reason and that's ok.

Personally I've got about 4 long blocks, with all of them a 484 or 509 cam, waiting to go in a roller. Picked up the cams at swapmeets, some new, some slightly used.

The combo closest to dropping into my 69 Rr is......

.030 over 440
KB hypereutectics
.509 MP cam
516 bowl ported heads
2.08/1.74 valves
Holley SD intake
850 Holley DP
1&7/8" Hookers
3400 Coan converter
rev. man. valvebody
4.3 or 4.1 gear
