Cough.....Well this year has flown by! I had one hell of a bachelore party 2 weeks ago. It Started out late afternoon with endurance style Go karting. I had invited some ex champ car race car drivers and car builders. It was a blast and I took third!. not bad for a trucker! Party ended at 6 am with the last topless waitress leaving after serving us for over 8 hrs. My best man Managed to keep me alive and not violate any contracts with her. I wont go into any of the top secret details but my sides have been hurting from all the laughs and pranks they played on me. People lousing kar keys in strippers cleavage. streakers at the hotel pool, strangers from another wedding trying to crash my wedding reception, friends passed out in the ditch next to the hiway at the reception hall, Forced drunken Motorboating just about all of her bridal partyand the list goes on and on and on... Suprisenly with all that madness she still agreed to get hitched this past weekend 12-1-12 Weather was in the low 60s no rain , We decorated my 65 caddy and my groomsmen and I stopped at the local tavern for one last drink. Church went perfect.Reception was a hit, hotel party ended at 7 am and woke up without feeling any different than before. She was stunning and brought a tear to my eye when she walked through those church doors. She even had a special grooms man cake made for me with my Cadillac,Mack,Blues brothers hat,Gears and Railroad items on my cake. Class all the way with this one! Thought I would share some of the results of the past few weeks. More to come later! Trent

rip....

2300 RPM (if my memory is correct of the shop manual). however that is the suggested max rpm. our sled pulling truck turns about 2600 with stock heads. someone had said old stock valve springs start to float near 3k RPM

If I recall there is also a detent for that stick. If its worn a bad bump can knock it out whith slack in the gears.

good point about the complete swap...A friend of mine was asking and I dident know if the axel housings were beefed up too or if it was just heavy springs and diffrent bushings etc... Thanks guys

I have the alum caps. Standard 34k housings and rubber bushing. I have hauled 90k with a low boy and she was squatting pretty close to the frame/axel stops just wondering how simple it would be to beef it up a little.

What do you need to convert. Is it just springs and longer u bolts.?

That 10 speed won't have a real low gear for off roading. But it should be fine if your off road is pretty much hard flat surface. Or minimal soft ground. The 350 was a good engine and simple to work on. Camelback is a great set up, check the frame. Single heavy is better than double in my opinion. The r model was one of the best trucks Mack built. It's easy to work on and parts interchanged easy...

Most block heaters were installed in the freeze plug on the drivers side. Early block heater plugs were just hanging down near the battery box. Later they moved them to the headlight panel. If the old heater went out they may have put a pad on it similar to a pan heater?

Don't you love those 20 year projects.... Looking good and that's pretty quick

Don't forget to hold it At full throttle when cranking with the injector line cracked open. This will help suck up the fuel faster.

Those old dogs move out!

There was a guy on eBay making some old logo flaps in white or black. I bought some 2 Yeats ago and they look great. Will have to search for the guy again.

Ok let me try... Early r 600 models had a small cab (metal dash) and short hood, in 73' they went to the +3 cab giving more rear room. I think in the mid to late 70's when the 300 came out the hood was stretched about 2" to help make room for the inter cooler. The new cabs will bolt on to just about any frame but check the hood size and rear cab mount locations.

It all depends on what your doing with the truck. My 285 in the dirt loaded I can drop the clutch and it will walk away easy my 550 cat will stall out unless I give it some throttle. Put both trucks on the Hi way and that cat runs down just about anything. As far as super liners. E9 for obvious power reasons but expensive to repair. for simple power and cheap a big cam cummins is a A lot of motor with good value. Cat 3406 make a lot oh high rpm power but also pricy to maintain. If you want big hp and not brake the bank it's cummins. If power and cool factor e9 or cat...

I like the one with the v8 R700 doing the wheel stand in 1st then a quick lift in 2nd

Welcome to the site. Sounds like your dad had some nice trucks. Someone on here was just looking for a c model

Just my.02 I think you could sell that steel nose and find a early to mid 80s rd in better shape,more HP and and still be ahead. I don't know how heavy you run but a bad frame that goes un fixed can cost you more to fix it than just buying a good used truck. If that putter rail is cracked,frame spreading, you might be chasing issues after every season. The double rail trucks were well known for these issues.

Need a sending unit for my gauges. Here is the oil temp gauge with its part number. Hope soneone can cross refrence it to the correct sending unit for it to read correct.

Here is the united pacific part number

Might want to have someone follow you in a car and have them pay attention to any sounds from the rear end and transmission. But a clunk every 5 seconds seams like a big interval for a broken tooth on a gear. I would suspect at 30 mph it would be more like every 2 seconds the broken tooth on a gear would come back around.

Pm me your email and I can hopefully sed it that way. This stupid I pad won't save the PDF and my phone won't upload the file. I was able to email it to myself and hopefully I can just forward you the file from my email,via my phone...if that don't work I may have to draw it put a stamp on it and mail it to you lol!,,,

Hmmm....ok i had tried to link it from my iPad...let me try again...

Brad maybe we can trade? Call me if your interested...
