GMC Motorhome: Another roller motor is coming

Before getting into it this morning, I just wanted tobrag a minute not on me but on my guys….. getting a group like this together that can do most anything…. brings a chill to my neck.  Here is our next delivery…. you could spend a boatload of money buying a new pickup truck or you could spend that money… maybe a little less but still a boat of cash and have something like this:  78 Ford pickup 4

A 1978 3/4ton, 4wd, 4 speed, 351 Cleveland Industrial motor, in dash AC, CD radio, PB, custom trim package, 16″ factory rims….NEW! 

78 Ford pickup 1 78 Ford pickup 3 It’s just a great thing and we have a 79 Ford pickup coming out next!  Now THIS is a true restoration shop!  I’m proud to be a part…..

___________________

Anyway, John E called in to say his motor was getting weak, blowing some oil and basically ready to go.  Taking an original, never rebuit motor over to our machine shop….. man, now this is a REAL speed shop!  Eidson motor 1Old guys and old motors RULE here!  Went back yesterday to see how they were doing…… The parts have been tanked cleaned and checked over  Eidson motor 4As we’ve talked before about our concave intake, the carbon cookie resisted the “tune dip”…… having to be chipped then hand removed THIS is why you need to block off the exhaust crossovers!  Eidson motor 7  If you have a rust stain through the middle of your intake, the bottom of the intake probably has a cookie like this…… I’m just sayin……  The bore was standard… Mike is looking to take it 20 over… the roller cam profile we use can use that extra lung capacity.  The crank is standard and may polish out at 10 over Eidson motor 6  Heads have pitted exhaust surfaces and a couple of sunken exhaust seats…. Mike will install new seats on all exhaust holes, recut exhaust manifold surfaces and set up for our roller rockers and cam  Eidson motor 3  Now guys remember…. we are NOT doing all of these hi performance things to make John’s coach burn rubber…. we build these motors strong like this for it to try and live pulling 12,000 pounds.. or in John’s case 10,000 cause it’s going into a 23′ 1973 coach…… will be a burner but don’t drive it like you stole it and it should do well.  Be cool and it will help… that’s why we do all of this.  A low cost production built motor… with all the crap parts and rush today, that kinda motor is just taking too much of a risk.  Sorry but this is the reality of it…. “Build it strong and drive it easy”  Eidson-awning-2

Loving their baby, John has this coach just the way they like it.. now with a roller cam motor, fresh transmission and all the stuff that goes with all of the project I have every hope it will continue to service their needs …… stay tuned for more on this project.Eidson-ext.-4

John S. coach made it to the lift yesterday  Luis in 3  Built here 20 years ago and maintained to the T’s it’s time to see what 20 years of living in New York has done to it…..  The fuel tanks out reveals the rust Luis mech 5 No rust thru but there is some surface rust and pitting Luis mech 2 The entire undercarriage is chemically treated and pressure washed.  The rear drums taken off, that and the wheel liners cleaned before getting into things.  Luis mech 3  This helps keep Phillip and Katlyn less greasy and gives us a chance to see everything  Luis mech 4  Getting a FiTech fuel injection system, the tanks and plumbing will be set up for that.  We’ll be adding a macerator to the sewer system, as usual the original body pads are crushed and missing… all the normal things we see are here and it can all be renewed.  This is a pretty special project having put this coach together 20 years ago… sold and with the new owner setting the coach up for his wishes it makes me feel good that things we put together last and are still good looking and desirable … this is the day of the coach coming back to the fold… stay tuned to see what we’ve done to it nowSalizar appraisal 1

Finally, I had a great day yesterday getting some seat time delivering Steven’s coach for it’s next restoration work  Steven delivered The guys pulled another one out of the hat getting my  towd fixed back up after the accident…. Looking menacing to me it still tows like a dream 11.28.17 morning 1  So 3 hours seat time in a nice driving coach followed by a 2 1/2 hour ride home in the Rocket Suzuki…. what fun!

So the beat goes on…. I’m tearing apart the Firewall in Texas Tux to catch it up to Ruby’s condition…… Hopes Monday out patterns will come in….. still having fun with that project so stay tuned….. see ya later.
