rocker arm ratio

[hotrod1994]

is there anything i have to do differently to run a 1.6 ratio on a sbc instead of a 1.5 rario

[fast75vega]

just install them and the push rods... then turn it over by hand to check clearances to make sure your not bottoming out the valve/springs. might have to change push rod length pending on cam size

ok it gonna be a farily mild cam solid flat tappet 525/525 with the 1.5 ratio

[hotrod1994]

and is it worth the extra ratio it will be a 355 with 10:1 c comp 294s soild cam pro comp aluminum heads hurricane intake and a holley 750 looking to get 450 out of it
comp cams cam quest said 500 hp with the combination and that cam

Check the wipe of the rocker on the valve tip. You might need to alter the push rod length.
