Roller Cammed 318/360
Nice addition there buddy, er ramcharger.
The thing with the roller cam in the past, also, is there were no real street grinds. Only the brave or crazy did them. And they were large cams even by todays standards. Poor idle quality and power bands that start @ 4,000. Hell, the assoc. parts made for a real mean machine power plant, but not exactly what 90% of the people are looking for that monster.
Todays roller cams for the street will out power the similar solid or quick ramp Hyd. cams like said above, but the best thing about them is they do give out a better nicer broader torque curve that has very real world useage. The argument on roller vs. quick ramp Hyd. is often a bitter one when engauged. Both sides make very valid points to there use. It now becomes tasters choice.
Now, Crane and Comp to a degree offer smaller rollers for everyday useage in power bands that start as low as 1500 rpm's and emissions leagal cams that have starting rpm point as low as 800.
Another porblem with the MoPar camp is the corp. (Chrysler) did not make very flexable computers for cam changes or much anything else. Ealy Dakotas and Rams where you could find roller motors were held hostage to the computers narrow parameters and the tail pipe emission testers. Re-flashing or replacement was out. No such or true rare animal.
The future of these truck Magnum engines are junk yard or possible hot rod truck. The hot rod truck will have to wait until there in excess of 25 years old in New York to be exempt form tail pipe testing and free to hot rod as seen fit. Once there this old, there computer can be tossed/replaced or reinvented.
It is a long time to wait.
