I'm new to the forum, the proud possessor of a '54 Willys station wagon with a Y-block (312, as best I can tell). It's running an old points-style distributor, and I want to change over to an HEI unit. Any thoughts on which HEI distributor works well with the Y-block?
Thanks!

Identifying your distributor should be easy. If it's an original 55-up distributor, simply remove the distributor cap.Pre-57 distributors (Loadomatic) are vacuum-advance-omly; the advance springs are visible on top of the breaker plate. 57-up distributors have both vacuum and centrifugal advance; the advance springs, being under the breaker plate, are not visible. Loadomatic distributors have a red ID tag riveted to the distributor body. 57-up distributors have the ID cast into the body/w no red tag. Ted Eaton tested a CRT/TSP aftermarket electronic distributor and liked it enough to recommend it over an original 57 tach-drive distributor. CRT has two styles, with and without tach-drive. Some people have reported clearance issues with the aftermarket distributors. If you have an original distributor, you have the option of simply replacing the points with a Pertronix I or II. 

I have no idea how much clearance you have with a 312 in a 54 Willys wagon. 

Here’s a link to a previous discussion about some of the various electronic distributors for the Ford Y.  Included in this particular thread is a post that includes a list of links that will lead to other discussions.

Thanks! Not a lot of room in there, so thinking it's going to be remote coil.
