Have been looking at the Coan LW 400 with the 2.48....and comparing with same trans with the 2.75. any way to determine existing trans 1st ratio? It's a Kilgore deal, recently freshened locally, but the trans guy said he couldn't tell and Kilgore "couldn't" locate original build paperwork.

A couple observations about your posts,
1) In your first post, you mention 5:14 rear gear. That's a bunch of rear gear for a car that should hit 125 MPH. You are going to need a really good BBC.
2) You stated that you already have the converter. The converter should be the last thing you buy, built to the finished engine/transmission/rear gear/tire combination.
3) There is a lot more to converters than stall. "K" factor, lock up potential, plus fin and stator design are all factors in the converters performance.
4) If you already have a real Kilgore, you already have an "expensive" transmission.
5) If you are looking at Coan, you are looking at an "expensive" transmission.
6) If your transmission was just open and your transmission guy could not tell what ratio was in it...well to be blunt, you need a better transmission guy.
7) If you have a real Kilgore, he has multiple ratios available.
