Sonoramic!

They only made one length of long tube cross ram, although they did make a version with a shortened divider for racing that is proably worth it's weight in gold these days.

Sonaoramics were supposed to have gold rams and could have gold valve covers......its tainted LOL

according to allpar there were 30" rams too but they dont have the specs on them....Thought this could be a set

You were right, a shortened passage but the same length...should never doubt you... ;D,



A very interesting photo as it shows the "short" long rams which have the 30" tubes, but with "tuned" passages that are only 15" long. Note how the valleys in the tubes only go from the heads to a little past the coil.
This was supplied by the Chrysler Historical folks, but with the caveat that it was retrieved from storage without any explanatory material. I suspect it was some special competition equipment from the Chrysler performance guys. My suspicions are reinforced by that coil which does not quite have a MoPar look (I think it may be one of those special Mallory coils of the early '60s).
Furthermore, if you examine the photo very closely, especially the left side of the picture, the exhaust headers don't seem to be exactly the heavy cast iron restrictive production types, but look more like specially fabricated low-restriction steel tube types.
Those three indicators in themselves point to three very important cars from the standpoint of Chrysler's performance history: one of the seven or so 300F "Specials" that Chrysler ran on the sand at Daytona in 1960 with the "short" tube 413s; or, Al Eckstrand's 340 hp/383 CID '60 Plymouth that took SS/A at the 1960 NHRA Nationals; possibly even the 1961 Dodge Dart 413 used by the Ramchargers at the '61 NHRA Nationals (driven by Eckstrand and Jim Thornton) which did take advantage of NHRA rules permitting non-restrictive exhaust systems and "over-the-counter" ignition parts with MoPar numbers (but manufactured by specialty concerns). However, in addition to an alternator on the pictured engine (those things weren't supposed to be used on anything but Valiants in 1960), there is a heater (pure drag cars ordinarily were heater deletes), though I can't imagine even a 300F "Special" not having power brakes (note no booster).
Whatever the vehicle, the short ram tubes are clear

I have an early 60s Hot Rod mag with an article about the racing "short" ram setup. Been a few years since I read it.
