I started to work here in 65 and didn't see the starter operation then (went right into the army) so not sure when they switched over but as late as the late 70's I was still repairing and making the old style starter with long shaft. I believe my 62 F-600 had this style and we called them "truck" starters. The bendix actually worked backward and came from the end of the shaft back toward the motor to engage the flywheel and the bendix was pinned or keyed to the shaft. The next generation was in production from the mid 60's to the mid 80's and is called the "positive engagement" starter and came in either 4.5" or 4" for large or small engines, had a much shorter shaft and the bendix actually rides on splines in the shaft and moves outward from the motor so is much more compact. The 4.5 with selenoid is called the 4 pole and is preferred for the 460 due to better torque. We used to make a modified version of this for AMC years ago. Now we make the geared starter similar to the chrysler type of old which started in the mid/late 80's and is touted to have even more torque but turns at 18k rpm on the input and 4500 on the output, same as the older style. The teeth on the new style will work with the 460's and I'm told is a good choice for cold starting etc. but doubt if there are any to fit the FE engines, not sure. I noted a tooth count change in the 351M/400 in a certain year (don't remember) by one tooth but they all use the same starter............??? Is this the kind of stuff the Ch**y guys use when they say fords are hard to work on cuz of all the changes???

Both have Disc brakes - both have Dana 60's in the rear and Dana 44's in the front. If I can find a Dana '60 front reasonably priced, I will change the long one over. I have a Dana '70 in one of my farm trucks that I might put in the rear, but it has 3.73 gears, and all my other axles have 4.10's front and 4.11's rear. If I could locate a front Dana 60 with 3.73 gears, that would be ideal. The Camper special is C6. The long one is NP435, but that too is subject to change. I'm contemplating some type setup with auto OD. The wife may wind up driving this one on occasion, and "Clutch" is not in her vocabulary, if you know what I mean.

Should I convert my 360 to a 390 or > go through all the pain and heartache of finding a 460/C6 and all > the mounts, manifolds, etc to make the conversion? I realize the 460 I would build up the 390 if I had ANY of the parts I needed since it can be made to run very strong, probably strong enough to keep you happy for a while and will require NO other changes to the vehicle or drive train. To use the 460 you will have the cost of a rebuild, new tranny, mounts, pan, radiator, any bracketry for accessories and probably a new drive shaft. This is all well and good if you enjoy tinkering but not if you enjoy tinkering with a race car instead IMHO. We only have so much time for tinkering............:-( I went with 460 because my setup already used the same tranny and initially because I built a 4x4 van which needed all new drive train parts anyway. It was a lot of work but worth it in my case. Puting that motor in the PU was a bolt in operation so it was a no brainer since I already had mounts etc made up and had the radiator and pan etc.. With L&L mounts it will be a bolt in proposition in the bronco so I will be building a new one for that project cuz I want to. Until then the 351M will suffice :-) Where's Murphy when you really need him?? - -- Gary -- ------------------------------ Date: Fri, 6 Feb 1998 11:17:38 -0500 From: am14 Subject: '65/'66 F150 I noticed on my way to work this morning a truck sitting out next to the road that might be for sale. It has a sheet of notebook paper stuck in the windshield, and I assume it has some information/pricing/phone # kind of stuff on it. If anyone is intere sted I will investigate. 1965 or 66 F150 2X4. Looked like the long bed - pale blue and white - chrome grill (this was Custom offering I believe). The rest I don't know about, but will gladly stop and look, if anyone has an interest. It was a georgous looking truck, just passing by. Might be a dog up close. I'm only on the list at work, and this is Friday (Thank God), so it will be Monday before I can get you any info.

I have had the SS hose on a 56 but only from frame to wheel cyl / caliper. At the time I was told that the SS hose was not approved for the use due to the fact that it melted in a fire and left nothing for investigators to examine afterwards ( I can not vouch for the accuracy of the last statement it was told to me 10 years ago by the people I bought the hoses from. ) I was sent a post a while back reporting a story where a guy was charged with manslaughter for killing someone when his brakes went out ( He had made some kind of mistake that caused the failure ) OOOOOOOOUUUUUUCCCCCCCHHHHHHHH!!!! IMHO Do it by the book! then there is no way for a problem.

The machine shop will "unbalance" my 352 flywheel in order to balance the 410 crank assembly, by drilling. No ugly counterweight-projectile things. Apparently, I probly wouldn't be too happy with a 428 flywheel for my application anyway, as I will be using smaller pistons and lighter rods than a 428 would. The shop thinks that I'll probly end up with a close-to-neutral assembly prior to balancing anyway, so a 428 flywheel would be overkill. As for a heavier flywheel, he says it could rob horsepower on acceleration, and since I'll have heaps of torque anyway, it shudn't be a problem. It isn't like I'll be hauling a yard of cement in the thing every day. marko ------------------------------ Date: Fri, 6 Feb 1998 13:16:45 +0000 From: "Gary, 78 BBB" Subject: Re: rebuilt distributor > Date: Thu, 05 Feb 1998 19:16:27 -0800 > From: marko > Subject: rebuilt distributor > I have a question, it seems to be made of gray iron, not of cast > aluminum like some others.

Motor Craft has to be late 70's early 80's and I've never seen an iron distributor housing as long as I've worked here so if it really is iron, lock it up and take it to the channel 30 antique show to have it appraised...............Really, I've never seen an iron distributor on anything, ever?? It must be discolored by what ever solvent they cleaned it with or preparation they finished it with. Pretty easy to check with a magnet..........:-) Does it have the number 12127 cast into it somewhere?

It came with the proper cap for a 360/390 though, the small blue one. I'll change that for a spacer and wide cap (yes, and the rotor too!). I could be just plain stupid (well, no I know that already) but I usually know Iron when I see it as opposed to Aluminum. Maybe they did sandblast it or something but it feels HEAVY, heavier than the smooth cast aluminum. They painted it cast iron grey so that is helping my impression somewhat. You know how a water pump looks when you buy it rebuilt, not a totally smooth surface on the outside, almost like those non-skid things they put on stairs? This is what the distributor looks like. I'll try a magnet, but if the dist could be magnetized, wouldn't that mess up the whole electronic ignition? Weird....maybe it's just a rough casting unlike the older, smooth castings which sure were pretty. I'll check at home for the number. ------------------------------ Date: Fri, 6 Feb 1998 12:40:47 -0600 (CST) From: RL Subject: Re:Differnce in Mercury/Ford Vans Since every one is talking about these vans.

Go > Ford! ---snip----- This makes at least theoretical sense since it's related to piston speed. At some point in the stroke the piston will be traveling faster with a long stroke than with a shorter stroke at the same rpm so will generate a higher velocity to fill the cylinders during at least part of it's cycle. The amount of time between top and bottom DC is the same regardless but at some point in the travel the speeds change between the two so it's believable that the intake velocities could be enhanced by this with long strokes. 78 F-150, 2wd, 460, C-6, 235's 78 Bronco 351M, Np 435, Np 205, 33's - -- Gary -- ------------------------------ Date: Fri, 06 Feb 1998 11:01:34 -0800 From: marko Subject: Re:Differnce in Mercury/Ford Vans > >Since every one is talking about these vans.

If you wanted a heavier truck, or a heavier van, you bought a ford. The mercury trim looks REALLY cool. Mercury is the old greek? roman? god with wings on his feet. Older mercs have little busts of the guy here and there in badges and stuff. The 1967 mercury truck has only different badging on the hood/fenders, and a different tailgate (lettering). Everything else was the same. The steering wheel and dash cluster both say 'ford'. I don't know about the older trucks. The 65 mercury van my friend has, has the cargo doors on the passenger's side. The Dennis Carpenter's econoline catalog for these things, showing only Fords, has the cargo doors on the driver's side. Is this a difference among Ford/Merc, a difference among model year, or just a goofy diagram in the Carpenter catalog? marko in vancouver marko 71 f250 4x4 67 merc m100 ------------------------------ Date: Fri, 6 Feb 1998 13:59:43 -0500 From: am14 Subject: "loops" Gary says: >>and took all the loops out of the line at the MC Yo Gary!!!

Sure... but wait until you work on '55-'58 sedan, an early V8 Nova, or a V8 Monza, or a 262 or 267 V8, or late model stuff, where the "interchangeability" of the small block Chevy goes to hell in a handbasket. Ford engines are *very* interchangeable; that's half of the hassle, as they're so similar. Here's a list of the 350ish Ford V8s: 351W,K based on the 302W, Ford Division design 351C 2V,4V Mercury Division "performance" design 351M large car/truck variant 352 FE Ford/Edsel "big" block - but actually smaller and lighter than a 351M That's three unique series (FE, 351C/M, 351W/K). And of them, the 351s share common bore spacing, head bolt patterns, and so forth, making them kissing cousins at least. For the Chevrolet crowd: 348 big block, smaller variant of the 409 350 small journal (1 year only) 350 large journal 350, "second" (really fourth) gen, one piece rear seal, rollers, revised intake manifold bolt pattern, external balance 350 LT-1 "third" gen, reverse flow cooling, distributor on front like a Ford flathead, every part except for the basic reciprocating assembly unique 350 Vortec, which is a revised, semi-interchangeable version of the "second" gen motor, unique intake manifold bolt pattern, etc. 350 LS-1 "fourth gen", whole new motor, Ford-type symmetrical ports and center thrust main (actually a 348 again, in case you want to annoy the "302 Ford is really a 301 liar liar liar!

All the manual flywheels I've encountered for 428's have the counterweight molded in the flywheel, and all are interchangeable. It is not a seperate weight welded to the flywheel. All the rest of the FE family (excluding 410) doesen't have this "cast in" counterweight and are 'zero balanced'. Just as an informational piece -- The 460's are also 'zero' balanced and carry the same flywheel to crankshaft bolt pattern. I'm using 390 flywheels on two different 460's right now.

I do have a 600 Holley in stock also though.... John this is all in what you want. I've had success with both. A fairly stock 4bbl 390 in the '61 thru '67 will give most folks all the power they ever need. Their HP and TQ fiqures are rated at slightly higher rpms than the 460 I think, but will still be ok with gearing as low as 3.00, so should be OK with the 2.75's. It is all a bolt in. No major undertaking. A/C - P/S and all remain in the same location with the same brackets. If your truck is 2wd then the 460 can be bolted in by acquireing the "stands" attached to the frame that the motor mounts sit on, from a '79 that came from the factory with 460. (It was an option, so they should be available). The tranny (bell housing, if standard tranny) will not bolt up. Different bolt patterns. Let us know what you have - (2wd od 4X4) before I proceed. I've done a couple of F250 4X4's, but the F150 4X4 is easier and the F150 2wd should be a 'breeze'.

So what is happening when you float a valve.

Yo Sleddog! If you run across any more of these bargain parts trucks that you don't want, I'm interested. I'll drive to NE Pa to get it. I could use a D 60 front and a D 70 or 80 rear now.
