i don't think you have enough tire to hurt anything except the engine when they break loose. back in the day we ran a 68 dart 440 and hemi 14-32 tire and didn't matter what gear, 4.10 to 5.38 pretty much ran same thing, just made converter work more, stock trans with vb. 1978 we ran 10.30 with hemi and 10.80 with 440. one trans. 6 years. 3.54 will give better cruise rpm.
