Location: San Antonio TX | I'm thinking about putting a ram intake on my 361 Chrysler. Will the intakes fit on the stock 361? Is there any major difference performance wise between the long and short ram intakes? They look really similar and I can't imagine there being much of a difference. Also, if I got the rams without carbs, is there any suggestions on what carbs I should put on the intake? I'd like to get stock, but if I can't get the stock carbs, I have no issue with after market carbs. Are there any other considerations I need to take into account if I were to put cross rams on my motor? All help is greatly appreciated. |

Location: Chicago | Don't think short rams ever went on a 361. For long rams, don't forget about the exhaust manifolds; the exhaust elbow from the exhaust manifold that leads to under-the-carbs for carb-heat is longer than the one for the 413. If you choose not to put the exhaust stuff on I wouldn't bother driving it below +79*F, but maybe that is okay if you are in Texas. Also, the cam is different, and cam sprocket is 4* off - at least on 413 long ram engines - so don't think you will see any performance advantage without looking into a cam, etc. |

Thanks for the info. All that has me thinking that a 4bbl with a regular manifold is probably the way I need to go. I had no idea that the fender wells were different and I really don't want to make any alterations to the sheet metal. |

Location: Eastern Iowa | I agree.
You will be opening up a whole can of worms there if you do not have all the right stuff.
And would probably wind up w/a "Custom by Cobble Craft" set up that will be a nightmare to get to run right.
They are bad enough to tune when all the correct parts are there! |

Location: Alaska | many years ago I ran the long rams on my 58 Fury 350 and later on a 383 in the same car. I did not have to cut any sheetmetal because I didn't get the special exhaust with the setup. It ran great in western Oregon, just took a little longer to warm up. It made a big difference in power in the midrange but power was dropping off by 4500-4800 rpm. The short-long ram raises the peak power by several hundred rpm and I would love to try one but these are very rare. Yes, the factory retarded the camshaft 4 degrees to help with top end power but I just ran the stock cam. hope this helps. |

| 58 --
In Darrell Davis' book on the '60 SonoRamic Commando, there are instructions on how the internal passages of the 30" ram tubes can be cut away to provide the "short" ram effect. I believe this is what was done on Al Ekstrand's '60 Fury that was the 1960 NHRA S/SA champ (he almost beat Jim Wangers' S/S '60 Pontiac for the top stock eliminator). I think Ray Christian also did the same to his '60 Savoy to win the A/SA class in 1961.
You might find that info of interest.
