Mopar made three different lengths on the runners by removing the dividers between the runners, I think the last version used the shortest dividers  As far as the power band I think they were all low RPM performers, under 4200 RPKM for peak HP and I think around 3200 to 3600 RPM for peak torque, maybe I'm wrong on the numbers so make sure and check them before deciding

I am considering buying a set to possibly use on my 440 in my truck.
Any idea if these require the use of special valve covers?
Would there be enough room to run a master cylinder and brake booster? Are you talking about the Chrysler 300 manifolds? If so I believe they require matching exhaust manifolds to heat the carb instead of the exhaust crossover.

What year truck?? I built a 440 Shortram motor,(same length as the long ram) and put it in my '81 W-150. You'll need to use a set of 60'e vintage valve covers, even the early 70's are to high and the rams won't clear. Also, you will probably have to ditch the brake booster and move the master cylinder. I moved mine 3" to the center and tied down the driver's side motor mount as it has 1/4" clearance.
After telling you all the bad parts now the good. They make mind-blowing low-end torque. My motor is 9.2-1 with E-STREET heads and an MP.528 solid cam with Doug's 1-3/4" headers. It make 512ftlbs@2500 and 543ftlbs@3800.
When choosing a cam for your motor err on the conservative side. The rams won't work with a big cam. The .528 was about as big as I dared go with shortrams. The carb pad will accept 500 CFM Edelbrocks , possibly 600's too but don't try and over carb the rams, Dave

The set I want are the long ram divided runners the entire length. 30" runner length including the intake runner in the head to the valve. They were tuned from the factory for torque between 2400 and 3200 rpm with the peak at 2800. Just about perfect for a truck motor that will actually be doing some light towing.

I am looking at the long ram manifolds that are divided the entire length of the runner. Cam will be 268 duration or smaller. I have a couple little 450 holleys from old 413 industrial motors and thought I might try those out. One thing I haven't been able to see from top side pics is how does the trans kick down linkage work? Would it be hard to fabricate without having the original parts? I am thinking a new style cable could be made to work but don't know for sure.

the kick down linkage is an adjustable rod that is attached to the bellcrank. it runs to the back of the engine where it snaps onto the linkage going to the transmission. i may have a PDF of the log ram from a FSM on the other computer. i'll have to look. it shows all the adjustment procedures and the order in which to do them. i think this info is also on one of the "forward look" sites, but i can't recall which one.

Yes from 1987...the long rams defiantly made more torque but a single Holley 800/Street Dominator intake made more HP (better Ets)

Kevin  I learn that lesson while flying piston driven engine airplanes  Manifold pressure starts dropping off along with the indicated air speed, slowly slowing down. Pull the carb heat and bingo everything got better
