What gear do I need ?

I have a 1949 AD 1/2 ton . I am putting a 250 six in it, it has headers, 4bl intake and a 460 lift cam . I am going to use a 3speed std trans. I am going to use a 1975 Camaro limited slip rear end, it has 256 gears. I am going with 15" tires. Do I need to change the gear?

I would...how tall your rear tires are and your rpm range along with your desired cruise speed will help decide..http://www.csgnetwork.com/multirpmcalc.html

Re: What gear do I need ?

2.56 might make that granny 1st almost usable haha

looks like 2000 rpm in top gear at 65mph, thats about what my 2500hd does with 4.10s and overdrive. it may be a bit of a mutt around town though.
