jdub396 Posted May 13, 2005 Report Share Posted May 13, 2005 Not sure what the stock Rocker Ratio is on 5.3's, but was thinking about slapping a set of rollers (w/ bigger ratio) on. How much, if any will I gain?? I will possible put a cam in, in the future, but for now, just wanted to do this....(if there's gain)??? Also...will I need to chance springs?

TurbochargedBerserker Posted May 13, 2005 Report Share Posted May 13, 2005 Depending on how wild you are going to go, I'd do either / or. Vinci / Crane makes a nice set with little hassle -- the even have that Crane exagerated lift thing (or something like that ) Quote Link to comment Share on other sites More sharing options...
jdub396 Posted May 14, 2005 Author Report Share Posted May 14, 2005 Can I expect any gain? Quote Link to comment Share on other sites More sharing options...
TurbochargedBerserker Posted May 14, 2005 Report Share Posted May 14, 2005 Absolutely. With these trucks in relatively stock form, you'll get about the same gains as from a cam. Quote Link to comment Share on other sites More sharing options...
SSLink Posted May 15, 2005 Report Share Posted May 15, 2005 You'll see small gains from the increase in lift and a couple degrees in effective duration but it's kind of an expensive mod for the HP you'll get. If you're going to do a cam at some point anyway, you can accomplish everything with just the right cam profile that you would with the higher ratio rockers plus a compatible grind. I would just swap in a high-lift cam with duration suited to your power and driveability goals. I think you'll be happier with the results and save some money in the long haul. With either choice you will need better valvesprings, and hardened pushrods are good insurance too. Quote Link to comment Share on other sites More sharing options...
