A 390 with a toploader? Your specific requests for information are difficult to provide answers to without a little more information. But here's an attempt to hopefully help you a little.
First, tranny info can be found on a metal tag attached to the side of the toploader(4 speed I'm assuming but there are 3 speed toploaders that were attached to FEs) but it's about 1/2" by 1" and it'll say RUG-.... this is the info you need to find out what the trans you have was originally bolted to.
It's very likely that you have a rather common big block toploader 4 speed that featured a 2.32 low gear with close ratio gears. Which in combination with your 2.75 rear gearing should provide for quite a slug pulling away from any line, stop or drag strip.
Personally I have found 3.89:1 to be excellent all around rear gearing with a 2.32/close ratio trans and mildly built FE. The 3.50:1 isn't bad either again for all around driving. |
