stock 58 apache rear end question

[billo92]

okay so i got a 58 apache 3100 for $500 delivered. pretty sweet except it was rotted out all over. this was about 6 months ago and after getting 99% of the body work done its time to start mach-up and building the motor, so my question is will the stock rear end out of these trucks handle decent power? this isn't going on the strip or anything but i want to be able to get on it once in a while- i'm throwing in a low compression 350 out of a monte carlo that i'm gonna put a semi aggressive cam in, high rise intake, holly built to 750 cfm, and full length headers. all i really need to know are two things- will the rear end handle this at full throttle (im hoping for around 350-375 hp) and what is the ratio in these things? i've been looking online and haven't had much luck finding specs or anything. ill keep trying though and thanks in advance for any help you guys give me.
