Anyone know of a way to get 1.5 rockers on the exhaust and 1.6 on the intake without having to buy 2 sets of arms? I currently have a hydraulic 484 lift cam with adjustable mechanical cam rockers (1.5 on all). Already have taller valve covers too. Thanks

Vendors will sell mixed sets. Call up Hughes Engines and they'll take care of that for you.

Thanks

I just changed from stock to Crane 1.6's on all valves, and the 60ft improved by .03. Not much for all that money.

there is not enough to gain here by doing that change, with that cam !
look elsewhere for far greater of pickup and hp
carb/cam (bigger) , gear .converter etc
if you do this make sure of the coil bind issue that may exsist??

if you already have adjustable rockers you might want to check the true ratio of what you have. you may be wasting money by buying new stuff.

I guess that would make your cam 516/484??? Wouldn't you want more lift on the exhaust? What's the rest of the set-up? Those MP cams like a bunch of compression, high stall and tall gears to work well. If you're one of those 9:1, ex manifold, 3.23 guys the 1.6 isn't going to help anything.
