Long ram 413

This is a very rare set of Mopar long runner intake manifolds designed to make the engines - mostly found in the letter cars maximize air flow, power, long ram 413, and torque. The long runners - noted by the ridge dividing the runners, long ram 413 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. All of the mounting bolt holes are clean with no damage except as noted with the heat tube area.

While the setups were relatively rare even when new and produced in their original form for only a few years, the principle behind them is commonplace throughout the auto industry today. In a common four-stroke engine, every time the intake valve slams shut, the air-fuel charge packs up behind it. This occurs because the charge has mass and inertia, and at 6, rpm it happens 50 times per second. Each time, a reflecting pressure wave is sent back up the intake passage toward the atmosphere at the speed of sound. Thus we can get more air into the cylinders and produce more output.

The factory carbs proved to be a bit too rich so they were jetted down about 4 sizes restulting in a final air fuel ratio average of right around

BTW, to all of you who suggested porting the heads, I caved and requested a good pocket port job. Mostly a street cruiser but yes, I do plan on doing a bit of drag racing with long ram 413, so far the plan is to install it into my 57 2 door Plymouth wagon which won't be it's permanant home, long ram 413, I have an early Hemi build that will probably be swapped in down the road. I have a rebuild long Ram engine that I plan on using in a fairly heavy car 3,lbs.

The B and RB engines are often referred to as "wedge" engines because they use wedge-shaped combustion chambers ; this differentiates them from Chrysler's Hemi big block engines that are typically referred to as "Hemi" or " Hemi" due to their hemispherical shaped combustion chambers. The corporation had been seeking a smaller and lighter replacement for its FirePower engines, in part because new styling dictates meant moving the engine forward in the chassis which negatively affected weight distribution. Design features of the B and RB engines include 17 capscrews per cylinder head , a cylinder block that extends 3 in In order to provide a lower hood and center of gravity, the engine to be mounted lower than before. Apart from changing the engine dimensions and engine mount position, this also entailed reconsidering the distributor drive and oil pump locations. The oil pump could not be allowed to extend below the crank throw to avoid interfering with the steering linkage.

Naturally, powerful acceleration was a key element, but it was intended to make premium models more capable on the road, and not meant for speed contests. Part of that perspective changed when the division released the C in Fitted with the hp, cu. Adventurous CEOs could feel the excitement of raw power while seated in a luxurious cabin, surrounded by coachwork that spoke of edgy—yet not audacious — exclusivity. Chrysler restyled the F with an aggressive front end and grille; the following year would see yet another restyle, this time with distinctively canted headlamps.

Whether that means power to weight ratio or putting huge engines in cars, Chrysler leapfrogged others. Painstakingly restored over many, the photos provided will reveal a truly extraordinary car in every way. Meticulously clean and accurate in every way you will just fall in love with what Virgil Exner and the Chrysler design team created. The "F" was special for several reasons, the most important is that it was the first Letter car to feature unitized construction for a more solid build and ride quality, and the cid - hp V-8 with the new Ram-Tuned cross-ram induction system and dual four-barrel Carter carburetors bolted atop inch-long intake runners.

It is several times greater than even in a four-valve traditional system.. Good news though Great info. After , it would be used only in Dodges and Plymouths. If your cam choice moves your upshift RPM recovery above the tuned speed, the length stops working. Message format Flat Threaded Nested. Knowing this RAM induction, I designed two such distinctive tubes for my engine. It produced bhp kW. All parts except for the pistons were interchangeable between the and The RB engines, produced from to , are raised-block taller versions of the B engines. The intake manifold side decks are straight with no distortion. Search Statistics User Listing. The fully divided long ram was designed for peak torque at a low RPM

While the setups were relatively rare even when new and produced in their original form for only a few years, the principle behind them is commonplace throughout the auto industry today.

I could swap some better heads onto it but since that would blow a big hole in my budget and will change the looks of the heads I decided against it. The last 'B-RB' wedge-headed engine was produced in August , ending the era of Chrysler "big-block" engines. I always loved the long rams well all cross rams for that matter. Veteran Posts: While these original Mopar Ram Induction systems were spectacular in appearance, they never caught on in racing applications because they were tuned for peak torque rpm rather than for peak horsepower—great for street performance, but not so great for racing use at max rpm. That's good information, and dispells the advice with the stock cam of istalling retarded. Any grind suggestions? Returns for non-fitment will not be honored — please ask questions first. Tuned to optimize for peak torque rpm, the Ram Induction intake runners on Chrysler road cars were inches long, and the carmaker claimed an improvement of up to 10 percent. Standard engine on the H was a hp, in line dual quad In the event of shipping damage, customers must save all packaging and send 5 digital pictures so Musclecar Air Cleaners can initiate a shipping damage claim. WARRANTY This assembly is guaranteed to match the item description — customers have up to 14 days to return the assembly after receipt if it is not as described. Before the end of the model year, Chrysler introduced the Stage II Max Wedge with improved combustion chamber design and an improved camshaft.
