493 Engine Block Camshaft Upgrade Front View
|
The previous solid street roller (left) proved to be an outstanding cam in performance and durability in our 493 combo. The first cam in our test features .575-inch lift and 262 degrees of duration at .050-inch, and a 110 LSA (lobe separation angle). The Lunati VooDoo stick (right, PN 60334) will have to prove itself against one-bad-bumpstick. The VooDoo has more lift (.600-inch), less intake duration (255 at .050-inch), but similar exhaust duration (263 at .050-inch) and a similar LSA of 110 degrees. We thought these two competitors had the makings for a good bumpstick battle. View Related Article
