  1. Haven't been on my account in years and just sat here and read all these Chicagoland r models posts. Lot of northern illinois history of Mack's here. Some guys had been asking the story on some of Mark Meade EXcavatings trucks...... They are all alive and export free sitting in our sheds. My RS700 hasn't had plates in 4 yrs....... I doubt we will ever part with our R models. Although we did sell our lowboy CL to Chicagoland paving.

  2. did you just simply modify your front crossmember or is there a western crossmember that will bolt up. Shouldn't be that hard to fab somethin up. I'm already set up with front air2air.

    We used an existing cross member from an E7 and made it fit in my frame because the 2 valve had a different mount

  3. I made a similar switch in a 75 RS700L from a 2 valve to a E7400, the biggest issue I ran into with my truck was we had move the radiator back for a front mount intercooler because my old motor had a tip turbine. Otherwise I can not remember other big issues, oh yeah motor mount was different on the front mine had the old style front motor mount and we had to switch it to the newer one to match up with the E7

  4. I have the 12 speed in my 1975 RS700L behind a E7400 Mechanical, and I LOVE IT! I don't think I can tell you how much I like this tranny. We have two RD's one with a 400 and one a 350 both have 8LL's, we also have a CL with a ISX600 and an 18 spd, and I will be honest with you I will take the old R700 any day over the CL, more low end power, and that 12 speed just drives like a Cadillac, once you get rollin you only need to use two gears because like a 5 speed 4th gear is high enough to do 40-45 and low enough to do 30 for rollin into a town. I hardly ever use the Low gear in my 12 speed only when you get in real soft ground when I'm off road.

  5. The only advantage really to twin turbos if they are staged and you want to get higher boost pressures, whic would be pretty cool, but would take a lot of work you would be better putting the Holset turbo on it, and maybe some different injectors, then youd really have some power, and it wouldnt be near as much work as routing all oil, intake and exhaust

  6. Good point Ron. I cant fit a intercooler from a 4V 300 between the grill and the Radiator on my truck. I have about 2 1/2 inches and I need 3 1/3 to make one fit :(

    Check on the spacing between the fan and your radiator, sometimes on the tip turbine motor you can make up that difference in the fan spacer, we ended up doing that on mine trent with the new E7

  7. It depends on which 300 to 350 you are talking if it is a 2 valve, no if you plan on going with the tip turbine intercooler on the motor, I believe and E6 4 valve would also swap the same, as would an E7 300-350, the only reason you would have to mess around would be if you went from a 2 valve 300 with the tip turbine intercooler to a 4 valve or late 2 valve 350 with the front mounted charge air cooler, then your radiator would probably have to be moved to accomodate the charge air cooler, there are several different variations that could happen here depending on the year and type of engine currently in your dog

  8. That 3208 is probably worth a lot of money now. The price of scrap metal is way up.

    HA isnt that true, junk clatterpillar, we've had only 1 or 2 3208s, but weve had a few 3204s in a D5, 953 and a couple other machines, god are they junk, head gaskets or heads have been done on all of them, 953 got an overhaul, blown a turbo, its half a 3208 basically cut in half, weve got several 3304s and they have been outstanding motors, my 955L has seen a lot of dirt in its day

  9. As previously stated the 3208 is definitely a boat anchor, Not only as said do they have crank failure but also common cracked heads and junk head gaskets, they are one of the worst motors cat ever built, all of the 32 series, about the 237 I believe it would be fine in front of the 13 speed as far as handling the torque as long as the driver drives the tranny right, if it was me i would put a maxidyne in it, my uncles is currently finishing up a b model with a 195 horse john deere powertech out of a log skidder in it, once its done i will post some pics on here

  10. first thing, junk the cummins and put a bulldog back in it, unless you really want it original i would either put a 2 valve in it, or an e7 mechanical, 2 valve 350 with the tip turbine intercooler best motor ever built never touch it, my uncle used to run his towing business thru my grandpas mack shop here in illinois, they got an 82 valueliner with 350 2 valve and 13 speed fuller, screw turned some it will outrun cars out of the toll booth empty, no older 400 cummins or clatterpillar will even touch this thing, and you can find 2 valves cheap, all you need to make a 300 a 350 is change the turbo, pump settings and put the water manifold intercooler on it, my rs700 has now got a e7 400 in it, set at about 425 now, when pulling season rolls around and i gotta go up against a few petes with c15s will set her up all the way, ask trent even the old two valves will scream though, two seasons ago i outpulled a buddy of ours 379 with a 550 in it (rob's trucking/lenzini excavatings), i took 6th out of 17 trucks with a 300+,

  11. As long as you take care of the motor and truck, it will run forever, theres lots of bulldogs out there pushing over 1 million miles that trucks just broke in, it could have 200k on it and be junk cuz the previous guy was a pig, if it was taken care of and you do the same thats all that matters, i know several people that run E9s, we own one

  12. its probably a dynatard engine brake is why it doesnt perform like you would expect, that was macks engine brake, it doesnt have the retarding horsepower of a jake, more for the noise than the actually slowing factor, you need to try and find an actual Jacobs engine brake, they are kinda hard to come by we have a 65 bmodel that my grandpa put a 237 in back in the day when they used it as a wrecker, and it has an actual jacobs that works awesome. Good Luck, Jon

  13. I have to agree on Daaa Bears, but since we couldnt git'r done im hoping the Iron Curtain falls upon those Seahawks, Pittsburgh is gunna rock Seattle, I myself will not be watching because we will be offroading in Lake Geneva, Wi, since the weather hasnt permitted excavating were gunna go play in the muddy mess weve gotten.

  14. it is sad that volvo bought them out the thing is guys, the MP7 and MP8 engines are both Mack built, they are both manufactured at hagerstown, and volvo is putting there name on one and mack on the other, so its technically a mack, the MP10 is forged in sweden but i believe it is assembled if i am correct in the states and i believe at hagerstown also, i would have been much happier if Deere owned mack just imagine a new deere 13 liter 650 horse in a mack, hmmm that would be beautiful

  15. pretty much exactly everything fullfuel said is correct, they are heavy, it costs more to rebuild a v8 injection pump thean putting an inframe kit in an E7, but they make un godly amounts of horsepower on ONE Turbo, and the sound of a thundering v8 is like none other ever heard :mack1:
