Oh boy here we go !!! Just bolt the engine together and don't worry about 04-.05 ratio.... For what your doing with the car it wont matter at all. Have a beer and enjoy the hobby and stop loosing sleep over thing that don't matter pity

No changes planned w/ this setup. It was very close to what it measured before w/ the same rockers and too-short pushrods; I was simply verifying the current net lift for spring setup purposes. wrench


Did you gain rocker ratio with the longer pushrod's, if so how much?
