I found some used roller rockers, ratio 1:7. Could I use these on a stock 454. And if they worked would it help me much. or if they didn't work what would I have to do to use roller rockers.
Another question I have is how good are those Proform carbs. I have a 700 double pumper holley on the engine now but it ain't mine I would like to buy carb that works better or just as good as this carb does. Any advice is appreciated. Thanks
