Bolt Length ???

[55 Fargo]

Hi all, need some info, I need to bolt up some items to my 251 Fargo engine, and they were not removed by me, so am not sure of some of the lengths, maybe some of you Guys might.

waterpump, has 5/16 thread, what length(s)

starter motor on truck 3/8 thread what length(s)

fuel pump bolts, what size and length?

If anyone happens to know, could you let me know.....thanx Fred

Fred,

Get a bolt of the appropriate diameter and run it in until it stops, then back it out a little. Measure that length and add to it the thickness of the case plus whatever washers you might want to use et voila! You might even want your son to do it because I'd bet he's itching to get his hands greasy plus it would show him a practical use for the stupid arithmetic everybody hates. Just a thought.

Thanx Randy,most likely something like that will be done.

I am bolting all of these times back onto the engine tomorrow, if I had a few more itmes I need, I could fire the engine up.

Fred don't do that with the water pump. They don't stop they just go into the water ports. If they are too long and sit in the water you'll have a hard time ever getting them back out. I had one like that on the engine I bought and after about an hour of spraying heating turning back and forth it still broke off in there. I think if you try a bolt without the water pump you can tell how far in you can go before you're in the water.

I agree with young ed, measure the thread depth and use a bolt that will be just shy of exiting the back end. And be sure to use a sealer on any threads that will be exposed to water.

The water pump has 5/16 thread? I though they were all the same and the parts book for my 1933 Plymouth (first year for the ancestor of the 218) uses 3/8" studs. I guess the "big block" uses a different water pump altogether then.

On the off chance that they are actually the same, my 33 uses:

One each: Short stud part 103196 (3⁄8-16-24x1 Plain steel stud)

Two each: Long stud part 112572 (3⁄8-16-24x1 5⁄8 Plain steel stud)

Hi all, went to the local bolt and bearing house, and got some supplies today. I bought the correct studs for the starter motor, course/fine, used grade 5 bolts to just enough to enter block threads but not to sit in the water jackets. I have mocked all this stuff up, still need to get gaskets tomorrow, and hose.

I need to put a kit in the carb, it is all cleaned, and ready, but needs a kit, the starter, needs brushed, but is like new. The water pump, t/stat housing is all used stuff I have colleceted, I am using an external water pump and t/stat housing on an internal by-pass engine, but am using the correct t/stat and short hose between t/stat housing and water pump to alllow the water to flow for the heater hoses.

Fuel pump and dizzy like new, all new innards on dizzy.

I have the ballast for 12 volt use, need a coil and plug wires.

I am looking for a 12 volt genny, or will mock up a mount for a GM single wire alt.

The rad needs cleaning and testing, it was closed, and full of antifreeze, so no mice in there.I am not going to pop freeze plus just yet, the water tube slid out, and was super clean. I also need to hook up a temp gauge, have that, and an oil pressure gauge too.

Got battery cables, need some fuel lines and fittings, and could fire, or try to fire this old girl up.

Here are some pics, please excuse the greasy dirty mess, once all is runing, will clean paint and detail, but I want to verify compression and oil pressure first. This engine was run and driven in a truck unitl 2006....
