Track Thrash
We were curious to see how quick the R/T would quarter-mile with its fresh stroker combo. We mounted the Hoosier 30x9x15-inch slicks and 26-inch front skinnies before pulling up to the line. At this point the 950 HP and the 3.73s were still part of the R/T's equipment. Out of the hole, the slicks spun and we received a 1.60 60-foot time, but we still ran an impressive 10.70 at 126.40. We pulled around again and heated the Hoosiers again. This pass produced a no-spin 60-foot of 1.50, enabling the big B-Body to boogie to a quicker 10.56 at 126.10 mph! We can't tell you how happy we are to have a 10-second, pump gas, real street car.

Conclusion
Roller cams offer better lobe profiles than flat tappet sticks, thus better performance. We honestly can't say which bumpstick won our test. Using a chassis dyno with a loose converter was not conducive testing. We've heard of racers going quicker using a motor that showed less hp on the dyno. It's always in the combination. If it's in your budget, a roller cam matched to your combo is the biggest winner.

Note: Please read the captions to see the trials and tribulations we encountered to perform this cam test. We hope this prevents others from experiencing valvetrain component problems. Pay close attention and don't be afraid to ask questions on the cam tech line about your intended cam and valvetrain parts combo for your engine.
