1960-61 Chrysler 300F 300G Long Ram Intake Manifolds with Crossover Tube, Linkage, and Air Cleaners. This is a very rare set of Mopar produced long runner intake manifolds designed to make the 361 383 413 RB engines - mostly found in the 300 letter cars maximize air flow, power, and torque. The long runners - noted by the ridge dividing the runners, were designed to generate maximum torque for the iconic C bodies on the marquee Chrysler letter cars. This is a complete set of both intake manifolds, both air cleaners with correct carburetor flange, and mechanical linkage.

Condition: The manifolds remain in all aluminum as cast with no apparent cracks or distortion in an attempt to assure there is no damage or repairs. All of the mounting bolt holes are clean with no damage. The intake manifold side decks are straight with no distortion. The bottom is clean and free from any defects. The interior runners are course as cast, as is the interior of the choke pot and carburetor flanges. The air cleaners are original, but have been modified for additional air flow (still very usable, but unfortunately altered); they have been refinished and come with new heavy duty air filters as well. The original crossover tube is optimum, as is the mechanical linkage.  The Carter AFB (2903S) carburetor base on the intakes are intact with studs and feature the smaller spread bore bolt pattern - more modern iterations by Edelbrock/Holley may be used when they feature the dual 4 bolt patterns, but they will not fit the small diameter air cleaner bases.

This assembly presents well and will enhance your restoration. Best of all, it is an ULTRA RARE and genuine Mopar part!

Many of our parts are available only once - we cannot predict if/when another will become available due to the scarcity of original parts. The old adage "here today, gone tomorrow" applies to many of these unique assemblies. While we strive to maintain a strong diversity of desirable parts, there simply aren't enough available to meet demand at times. 

For further information on the restoration process, please contact us directly.




This assembly is correct for the following 1960-61 high performance models featuring the 361 383 413 (RB deck) engines:


300F/300G, Select Imperials, 

The assembly will fit a myriad of A/B/C bodies featuring the RB engine for an extremely cool and exclusive look too. While we can't guarantee fitment in many models due to the width of the runners, some modifications may be necessary if you apply these outside of the factory intentions.

Note: the manifold head flanges are specific to the RB deck engines (413/426/440). The geometry of the 361/383/400 B deck engines is different meaning the angle of the cylinder head is off by 7 degrees and will not fit without some type of angled adapter.   



The assembly will fit RB engines. If you have modified your engine/heads, please inquire first prior to purchase to ensure fitment is correct. Return requests for non-fitment will not be honored.




The assembly will ship within one day (usually the day of payment) with shipping/tracking information provided.
