So is there a down side to using higher ratio rockers? Why bother with the stock ratio then, everyone should put the highest ratio rockers in they can as long as their is enough piston to valve clearance and when your rebuilding an engine that shouldn't be a problem.
It depends on the profile of camshaft You're starting with. If the cam is mildly aggressive, say a Comp Cam 280 Magnum, it would be a nice bump in that cams effectiveness
w/o too much worry about having to run super-stiff pushrods & high spring loads. If it's an extreme velocity design based on pushing how much You can get away with on the
lifter dia. you're running, You have to be prepared to pay the freight for that, and Your build would have to warrant that. If it's a roller cam, well, you will be upgrading the
majority of those things anyway unless it's a mild street roller.....in which case there wouldn't be a need for the increased rocker ratio........................
