The camshaft choise, will vary, whether or not it has a fuel pump drive lobe on it.

The Truck I put that fuel pump on, had a flat fuel pump drive lobe.

The picture is on the first page it was just showing that it has the hole for the push rod... How do I determine which cam it has... my only quess would be push rod up the hole and turn motor by hand and see if it pushes...right or is there an easier way and right now this is little on the motor to turn it over with.

Get a push rod and turn it over by hand, if you are the only person around. It should have, at least, a movement of about 7/16".

fuel pump.

unless you are using F.I.,stay with the mech. pump.there is a plate with 4 bolt holes,,and a large hole for the pump arm to go thru. put permatex on block,then gasket,more permatex, install pump push rod, install plate with 2 bottom bolts. plate will stop push rod from falling out.
push the pump push rod,up into the hole,using balancer nut,turn engine til pump rod goes up all the way.in front of pump mount,(bottom left side of block) there are 2 bolt holes 5/16????? holding push rod up,(with finger) put bolt into top hole (of 2) and snug it,to hold push rod up,if rod slides down,snug it more.then install pump gasket,and 2 bolts ,to hold pump,remove bolt (holding push rod) replace bolt with shorter bolt. or you will have an oil leak. im not sure what bottom bolt is for,but,i always put a short bolt (with permatex) in both holes...have fun.

Ummmm....what?

That block will obviously accept a mechanical fuel pump, slide the fuel pump pushrod into the hole, lock it in place by inserting a bolt into the appropriate place in the front of the block. install the plate listed in the link above, then install the fuel pump and back off the bolt in the front of the block.

Install a few flat washers under the bolt in front of the block and tighten it back down so it will be there if you ever need to remove the fuel pump. Just make sure you have enough washers to keep the bolt from touching the pushrod.

As far as camshafts go, the one you have in there will most likely have a lobe for the fuel pump pushrod. if you are concerned that it does not then install the pushrod and turn the motor over and see if the pushrod moves.

Most camshafts come with a lobe unless the are a factory GM cam designed for motors with fuel injection.

Thank you for all the help... Definitely gonna go with the mechanical pump... My car is just a cruiser and have always had good luck with the plain ole mechanical pump. Although I did learn about relays, fuel plumbing, etc... This site is great... you start of with a small question... read a bunch of post... end up with five more questions... and learn 10 things fiquiring out your first question... If that made sense.

You might be able to score a plate and pushrod at a local machine shop too. They usually scrap their fair share of blocks over the course of a few years.

[QUOTE=boatbob2] snug it,to hold push rod up,if rod slides down,snug it more...................... im not sure what bottom bolt is for,but,i always put a short bolt (with permatex) in both holes...QUOTE]

Don't twist too hard when snugging up that long bolt. It only takes a tiny bit of pressure to hold the rod up, and only a tiny bit more to bend the pushrod. It'll bend much easier than you might think, or at least easier than I thought the first time I did it.

Those two holes in the front of the block are where '55-'57 motor mounts attach, and some later-model blocks have the bosses, but no holes. If that's the case, bend a piece of wire that you can use to hold the rod up while you set the pump in place with the other hand.

The rod will go farther out of your way with #1 cylinder in firing position.
