[shaks 442 clone]

i recently bought a 12 bolt rearend in a package deal got a gas tank rearend and front disc brake conversion kit for 400 bucks

i was wondering what was the gear ratio of a 1970 442 because i heard they were a limited slip differential and im getting ready to do my rearend i was thinking of 3.55 but i rather go with what the 442 originally had

hope someone can help me out
