We have 2 great FWD performance companies marketing sliders and the other roller cams for high performance modified TDs. I'm sure there are advantages and disadvantages of each and applications where one is better than the other. But as I keep modifying my 2.5 CB and going all big valve porting, I'm looking for the best reliable option for a 12 second car with 350 whp. Still a weekend street with occasional track tuner.
