I'm assembling my 350 here, putting on the accessories from the 305. I'm not using the air pump, and I have no AC, so I guess that leaves me with water pump, alternator and power steering pump right?
This is a typical old style v-belt setup.

ok, so with that in mind, can my power steering pump just bolt directly up to the heads/block, or do I need these other brackets? The one circled in red, do I even need that, or can I just use washers to space things out?

Then in pic#2, do I need those other brackets, or are they just air pump / AC?

Thanks

 

I'm not sure what pic you are referring to but I'm not seeing anything circled in red. Also I'm in the process of figuring this same problem out myself so I am very interested in this thread. I have gotten to the same point as what you have in the 2nd pic

 

oops, wrong pic uploaded, ok, now one is circled in red.

someone else must have put together an old school v-belt sbc lately, right guys?

 

nobody eh? ok, i'll leave it as is, and hope for the best.

 

Well if you don't have the top bracket, how would you adjust the tension on the belt?

 

You need the brackets.

The long skinny one goes from the front exhaust manifold bolt, down to one of the old motor-mount holes in the front of the block. The big flat one goes under the 2 exh man bolts on the #1 cyl; along with the long skinny one. Without them, the power steering pump will just flop around out there in space. Note that those 2 brackets supply 2 of the 4 mounting points for the pump; without them, it will be held up only by the one pivot bolt, and one adjustment screw, specifically the one in the weakest spot, on the water pump.

The 3rd one is for the AIR pump. If you leave it off, put a SHORT bolt in the upper one of the 2 old motor-mount bolt holes on the front of the block that held it on; otherwise you'll have the famous mystery high-RPM oil leak.

 

karps, I thought it would pivot on one bolt, then slide in the arc in the other bracket, and everything would be good. Like the alternator....?

Thank you sofa!
I think you lost me a bit though, so i'll show you what i've done so far:

Long skinny bracket:
bracket1, I put on the motor in the upper hole, that I assume was an old motor mount bolt hole.
pic, drivers side.
I assume you mean I should plug the hole I circled in white? liquid teflon, on say a 3/8"x 3/4" bolt?

I've got the green circled stud as my pivot bolt, the teal circled hole in the water pump rides in a pivot slot on the power steering pump, and the stud on the back of the power steering pump pivots in the yellow circled slot. I assume I need some sort of spacer in the furthest forward drivers side header bolt, in order to mount that bracket eh? 3/8" ID, 9/16"OD tube of some sort? Maybe 1.25" long? I might drill out some 3/8" nuts if I can't find anything.
The power steering pump itself, it still mounted to some sort of bracket (perhaps that is the 4th one you're talking about?).

Then another Q here,
I've used bracket 1, which is the long skinny one you described, but i'm not sure which the "big flat one" is ?
bracket 2, or behind door number 3, bracket 3 ?


and then as a final (I promise!) question, do I have to plug the passenger side motor mount bolts ? Through the top one, I swear I can see the fuel pump pushrod...

Thank you very much, it's appreciated.

 

I only run bracket #1 on my motors. take a piece of 3/8's threaded rod and run it into the first header bolt hole on the drivers side. Put a nut on it. Then take another nut and put it on the rod and run it down a bit. Take bracket #1 and slide it on the the rod and bolt the bottom of the block. Once its tight put yet another nut on the rod and tighten the last 2 nuts down. That takes care of the spacer from the head. If you need pics ill try and get some.

 

For the love of God, don't do what i did in reference to the bolt holes in the front of the block. The top is a oil gallery that lubes the pushrod. Use a bolt, put it in with a sealant, liquid thread sealer by permatex is great. Make sure that you don't go to far and hit the pushrod. (for the fuel pump of course, a mech for those who didn't know.)

Btw for what it's worth, while you have the sealant out, use it on the head bolts that are on the low side of the head towards the fenders. If you don't there is a more than likely possibility that coolany will work it's way up and mix with the oil and thus causing you to have milky oil (useless).


Hope this helps.

 

thank you chevymec, I undestand. Good idea

gibson, so do I have to seal all 4 of those bolts in the front of the block, or just the top one on the passenger side, and top on drivers side?

 

What I do, is use the stock exh man "stud" thing for that bolt hole; and make a spacer out of 3/8" pipe or something, such that the spacer plus the header flange, is the same thickness as the exh man. Then, just put the brackets all on just like the factory did. Piece of cake.

 

yea, I think I lost that stud... oops...


sofa, do you tink I have enough bracketry ?

 

OK....

the hole you have circled in white, you don't have to do anything with.

Bracket 2 is the smog pump bracket.

Bracket 3 is the one I called the "big flat" one.

Where you have the red circle, is where you could use either the exh man stud and a spacer, or if you don't have that, use allthread and nuts like chevymec said.

You are exactly correct about the fuel pump push rod. If there's not a SHORT bolt in that hole with a drop of sealer on it, oil will get blown out of there. That's the only hole like that.

From 55 to 57, the motor mounts used those 4 bolt holes on the front of the motor. They didn't start putting accessories on them until MUCH later.
