Quote: Well this whole question was brought on becuase of the additive... We tried running a solid flat tappet with royal purple full synthetic and took some lobes off the cam . Should have known better. This car runs the 1/8 and we shift at 5500 and runs 7.20 consitantly or should I say ran... Its just a 440 that had a .590 purple shaft. Ran good and consistant had no complaints with performance. We dont really wanna turn that many Rs because we dont wanna spend the money to do so lol. So it sounds to me like unless we wanna turn mor RPM stick with the flat tappet and just keep the cam lube in stock.
A roller will make more power and if you keep the duration down you dont have to spin it higher and no you dont need additives... if the bottom end can turn higher and you have the flow I would turn it higher... RPMs make HP if your set up for it
