The first R models introduced were powered by Mack Thermodyne diesel and gasoline engines.

In the R cab was given a makeover to include a deeper rear wall for more room and a new dashboard design. Also in the movie convoy the main truck is a Mack RS L. The lightweight RL model followed inthe RW Superliner with a large, rectangular hood and grill inand the setback front axle RB in the s. In the s the R and RW were discontinued and the RB was introduced, mostly for severe-duty applications. The hood was modified slightly for the model RB.

I can take some pictures of it if you need them. It is mated up to a E7 I am currently having some work done on the transmission, there is a company called Clarke Power that has facilities all around the United States. They specialize in Allison transmissions. My local Mack has them do Allison trans work for them. What axle ratio does your truck have? Also does your trans have a rear support? I know the series requires one.

Sorry for the slow reply, been busy! I went to check the axle ratio and the sticker on the cab is not readable. Do you know where else the ratio might be located? I'll have a look for you. I know sometimes they're stamped on the differential somewhere Sorry it took so long to get back to you. My axle ratio is a 4. Late to the party, but two things, are you considering the cable or electronic HT ?

If electronic why not a series, has 7 speeds with two overdrives and have the best of both worlds? If the old cable shift HT is what will work I get why. Doing the same thing with a HTCR cable shift behind an E9 at the moment for the simplicity reasons. Don't need the super low first gear but instead using the high torque ratio torque converter.

I start now in 5th or 6th gear with an 18 speed and have plenty of torque. Then if all works out drop the rear ratio to 3. Being this is a swap, I suspect the shops are just high balling the price so you won't be shocked if a lot of fabrication is needed and the labor hours take off. Oftentimes with older trucks like yours it's cheaper and a whole lot less headaches to simply sell the old truck and buy another one with the components you need.

If that was the price I got it would be a BIG issue to. Have the drive shaft reworked for length but that is it. No engine work needed as it is all mechanical. Plus the cost of the donor truck No Way. You'll be time and a lot of money ahead. You can post now and register later. If you have an account, sign in now to post with your account.

The engine underwent some modifications over the years and was in production from the late s into the 2lst century. The E7 was a liter -- cubic-inch -- four-cycle engine that utilizes direct-injection technology.

The total power rating of the E7 was between and horsepower at 1, to 1, rpm. In its pony garb, the torque was foot-pounds at 1, rpm. In its horsepower spec, torque is 1, foot-pounds at 1, rpm.

Torque jumped to a massive 1, foot-pounds in the E7 with horses. In its horsepower design, torque peaked at 1, foot-pounds at 1, rpm. The highest-output E7 engine churned out horses and twisted 1, foot-pounds of torque at 1, rpm. The original E7 was turbocharged and featured a body-mounted, air-to-air after-cooled system.

InMack developed an electronically controlled and variable-injection timing system that it dubbed the Econovance Variable Injection Timing system and it optimized fuel efficiency and reduced emissions.

Mack used this system exclusively on the E7 engine. This improved combustion efficiency and fuel economy while reducing emissions, maintaining proper oil viscosity and expanding oil change intervals. The E7 engine series grew exceedingly popular since its introduction in Because of its relative popularity and quality performance over the years, Mack produced a total of 16 different versions of the E7 line.

If the engines are indeed the same model in both the RD and the RD, then someone has done a transplant, because as I said, the would have a Maxidyne such as "EM", or "EML", while the would have an Econodyne such as "E", or "E" etc.

The Maxidyne engines were made to work with the T, T, T, and T Mack transmissions which were 5, 6, 7, and 8 speeds respectively. I have a 94' RD, and it had an EM7 It can from the factory witha fuller 9 speed which we later changed to a fuller I was told by a retired Mack engineer that Mack would put whatever you want in a Mack if you requested it.
