Pictures would help, but I'm sure it's probably the original Holly "94".

 

Three bolt base? Undoubtedly a 94. Although there are many subtle variations of 94's between cars and trucks, the innards are virtually idential. There is little reason to get a 7RT-xxxx vs. a 8RTxxxx or whatever. The key things things to look for on your carb are: existence of an extended shaft on the driver's side for a throttle cable, along with a lever and spring-loaded cap; whether the air cleaner mounting is double-tapered or straight. For a rebuild kit, all will be the same in the BonusBuilt years. I would check Vintage Speed for a quality kit.

In a rebuild, one of the key areas that is difficult to clean, but makes a world of difference, is cleaning the "dip tubes" where air is bled into the gas drawn thru the main jets. The space between the outer tube and the inner tube, as well as the tiny holes in the outer tube, get packed with junk and are very hard to get really clean. Soaking and some time with a copper wire strand pay big dividends in economy and smooth operation. (see sketch)

You asked for the time and I've told you how to build a watch, oh well! The complete manual for these (actually for later models of the same basic carb) is here:
