Well I didn't stay away for very long.

I have been after this A Car for just as many years as that B-71 Mack. I lost where this A Car went for fifteen years a week ago I found out where it's been hiding.
One of the outside parts salesman that call on the shop was just grinning when he showed me a pic that he took of an old truck. I showed him a pic of the same
rig from the same vantage point. It is now minus the bed and hoist and has just been setting in the weeds for years. I will know sometime this week about the
price. I'm figuring it will go fairly cheap, well under a $1,000.

I have a BC-IV 400 cpl 676 non STC engine. That CPL 676 was a great engine when converted to full flow cooling like the BC III, plus change after cooler. And I
have the BC III parts to change it over. The first IV's had high compression and the cam had more valve lift, plus the block used lower press fit liners. With out
a huge expense you can get 475 HP out of one and it's still reliable. If I end up with this A Car, it just might have 400 plus hp.

Any A Car from the 60's with quad headlights is pretty rare. Over 90% came with single lamps. I think the first year for them was 1963. That's one
of the reasons I have been after this one. I don't remember the year and model of this one for sure but I'm thinking 65 to 67. The last time I saw
this A Car it was in real good condition. I found out it still ran when parked or moved last and that was six years ago.

Those are fiberglass fenders too, IIRC. The only A-cars without steel. Fine looking trucks. Will we see a concept drawing soon? I see some big pipes and a visor in her future. Maybe a long slide 5th wheel, lowboy ramps, and a bullet proof cab guard? Oh, wait... that's my inner voices talking. I always wanted one of the big boys with a setback front axle and flat fenders. Feed it a 12V71 and drive it to church. :D

Well the first thing is the price, I won't pay allot, you have to buy these old trucks fairly cheap because of the amount work and expense. If this one does still run ok
I might leave that engine in it. But I'm sure it has an SP switch-24 volt starting system, that would have to go along with any bad electrical. Then there's the air system
that you know is tired and valves out dated along with the air wipers. Cooling system, all the hoses and maybe a water pump and stat. Then the brakes them selves.
then suspension bushings and steering. Which I would covert to power box. Old trucks take time and money and some times less money if you do your shopping right.

But I don't own it yet so right now I still have money in my pocket.

Yep, nothing worse than rotted wiring with plenty of "fixes" and rotting air hoses. I once replumbed an old Pete with all new nylon and it wasn't cheap.

Ain't that the truth. The nylon tubing isn't so bad it's the DOT brass that kills.

Going through the start of this thread I stated that the BC IV had lower press fit liners going back through some of my old info notes -That is incorrect.

The NT 88 was the first 855 Cummins with lower press fit liners. Which I should have remembered because the lower press fit came out in 1988. Sorry

I should know early next week on weather I will buy it or not. But I finally got some info off the data ID plate. NH 250, Spicer 8054 front and 8345C auxiliary air shift.
You didn't see to many air shift auxiliary set-ups. Aluminum case front and rear I believe. SQHD's on 40,000 lb beam biscuit rear suspension. If I do end up with it
who knows what engine, trans or rear ends and suspension it will have.

Had many big cam's updated to lower press fit liners. You very well could have had a BC4 with lower press fit liners. Have to really watch that on overhauls because there are over sizes as well.

That's true- any big cam can be machined for lower press fit-I was stating that the first factory Cummins Lower press fit didn't come out till 1988.

If your not hauling with the old girl and the 250 is a decent runner... I would be tempted to freshen things up a bit and call it good. In the early 80's I ran a 61 KW occasionally for a guy out of Quincy with a 250, It had a center dump exhaust manifold and a set of 5" pipes with a VERY SMALL 4" industrial muffler under the cab. The sound was awesome. There was another gent in the same area running a59 KW with an old 220 with no muff and 5" pipes as a 10 wheeler, WOW, it really sounded good.

Who knows what I will do for power. I also have a 335 available with jakes that I might use. The only thing I will use it for is a yard dog. Those center dump manifolds
always did sound good with twice pipes. But this one will only have one 6" straight pipe. And 220's sounded good with only one straight too. But the one thing that will go
is the married airshift boxes. A direct 9 or 10 sp with a 8341G progressive auxiliary. That is a real nice gear ratio set-up. Parts are about extinct for those aluminum
cased gear boxes an just as expensive. I do know where there's a set of out board hubs and good drums on some SQHD's for next to nothing.

Oh, I forgot to mention... Not sure how the timing and pump was set on that old 250, but it ate 318 Detroits for lunch. Poor old James included.

Are you trying to stay original? if not an electric wiper motor from a heritage cab Western Star would probably fit.
If the NH is tight you could always put the turbo etc from the 335 on it, you shouldn't have much chance of melting the pistons if you keep the fuel pressure somewhat reasonable.

I had a '67 western star with a NH 250 and 4 x4 unit spicer, it was twin stick though, even 30 years ago it was hard to get parts for those transmissions, it was cast case if I remember right.

Found out the old girl has been converted already. I was wondering because the exhaust was run between cab and frame, not under.
It has a 335-13sp with four speed brownie. And someone told them it's an heirloom, so still dickering on it. But I was right on
about the year-1965.

Well I finally got time to go look at the A-Car. Mother nature has done its damage, floor boards rusted out and bad rust under windshield opening.
So she stay where it's at.
