jlosh20s Posted December 17, 2009 Author Report Share Posted December 17, 2009 http://www.silveradoss.com/forums/index.php?showtopic=59633 i could see it being a wast n/a but should be pretty good gains with FI?? Quote Link to comment Share on other sites More sharing options...
sprayed99 Posted December 17, 2009 Report Share Posted December 17, 2009 (edited) i could see it being a wast n/a but should be pretty good gains with FI?? negative ghost rider.... LOL the stock rockers are the best thing out there other than a shaft mount jesel. the aftermarkets are heavier and move more mass over the valve. A ton of f-body guys tried the stock ratio rollers when they came out and actually lost power. I would change the cam and supporting valvetrain. Then get a set of the COMP trunion replacements or CHE precision bushing kit... then spin that sucker.

jlosh20s Posted December 17, 2009 Author Report Share Posted December 17, 2009 im aware that it would be a wast of time installing stock ratio arms that would be 1.7 on a 5.3 im looking at putting 1.8's ive read on a n/a motor it has put as much as 18hp to the wheels and i would think that you would get more with fi im not really worried about the roller portion im more interested in the extra lift so has any one doen this with a stock cam and supercharger if so what were the gains Quote Link to comment Share on other sites More sharing options...

Even after upgrading the trunion, they still dont have a roller tip and with aftermarket heads that have bronze valve guides will wear and put strain over the valves. The aftermarket rockers (harland sharp) are lighter than stock as a whole and over the valve at the tip, I know because I weighed them. But to the OP... Like everyone said, just get a cam it will be a way better gain. Good luck Quote Link to comment Share on other sites More sharing options...

Also I know that titanium retainers are pricey BUT they are 5 grams lighter than the stock ones and will help with your valvetrain. Quote Link to comment Share on other sites More sharing options...

Good luck More internet knowledge run-a-muck.... then tell me why guys are spinning 8K with stock rockers and are running them for 2-3 seasons with no problems?? Now if you are going to be a serious buy the jesel set up or run the trunion replacement. By trunion replacement I mean the CHE pricision bushing set up... If you know anything about that....
