Tech Question
Jim Johnson, Lawton OK, 1969 Dodge Charger 440
Rick, I just traded for a 440 for my '69 Charger and it came with a cast iron factory dual four barrel manifold (inline carbs) casting number 2264877, along with 2 - 500 cfm Edie carbs on it. My question is what year(s) or motor could this have originally been on? My uneducated guess would be a RB 383 or 413. If it works well I would like to run it as it looks pretty cool. Anyway, thanks for any reply in advance.
Jim, yes, that's from 413s, such as the "base" 62 300H, '59 300E, etc. It looks cool, sure, but almost any decent 1x4 setup will make a bunch more power; it's a very "low rise" intake. I think even the stock late-'60s / early 70's iron intake manifold made more power!
It's plenum volume, runner size and height, that matter much more than venturi area. If you put two 625s or 750s on, then MAYBE...but driveabilty and low-end would suck.
Incidentally, I never saw a RB 383 with anything more than a 2-Bbl., although your manifold WOULD fit.
Sorry to be the bearer of bad news. Don't shoot the messenger!
Rick
