About the only hole that bolts to the heads is one and that's only one some models if i remember right.The older style pump that goes all the way thru the water pump mounting works good the newer style uses a threaded mounting and doesn't seem to be as alignment friendly, the later style water pump can be drilled thru for the older style,the outside mount that has the adjustment mounts to the front exhaust bolt,other than that you shouldn't have any problems.

i use the complete pump and brackets off a metric impala takes a couplr shims and washers here and there but works great a buddy of mine uses the pump and mount off a chevy van it works pretty good to i don't like it because it drops the pump down and i'm afraid it will get hit by some mud but it has worked for him we bolth run long style water pumps tho your is for a short style pump you might want to look for an older chevy truck like late 60's early 70's

I use the stock pump and bracket and I use heads with no accessory holes too. I assume the car had a 350 in it, it's a 78 Caprice, but I got it with no engine, it just had the power steering pump with bracket still attached wired up inside the engine bay. The bracket bolts in the threaded hole toward the bottom of the block on the drivers side and I it wraps around the head to bolt onto the first manifold bolt hole. I use one bolt and run it through the bracket and manifold, but I had to use a cutting torch to slot the bracket, if you don't it hits the front of the head and won't let it wrap far enough around to line up with the bolt hole in the exhaust manifold.

17j is right i was only referring to long style water pump,the low slung style is all i know for short pump.

I used a non threaded shaft pump and the speedway bracket and double pullies.I took out the bolts on the back of the pump then
got the threaded bolts out of the pump with the threaded studs and put them on the back of the pump.And i use a long water pump

you need the pump off a astro van or a full size van with the Pump the run down by the crank..I ran the hump heads with no pump run sits real low and has a very short belt..

What are your opinions about Steve Smith's book, ...Suspension & Technology where he recommends using a Z28 steering gear and pump ('82-up) with a '76-'81 T/A pitman arm?

alot of guys run the iroc gear boxes a pump is a pump so realy it's just how you want to mount it that determins that

The Z28 box is 2.25 turns from lock to lock as opposed to 3 for the stock metric box.

If you can't use a quickener, its great.

So, c21.......when they talk about a 16:1 box they are saying that the steering arm moves 16 degrees to one revolution of the input shaft? So the higher the number, the faster the box? Thanks!

Nope...16:1 means that for every 16 degrees of pinion rotation the output will rotate 1 degree. The higher the number; the slower the box. 12.7:1, 12.7 degrees of input for one degree of output rotation. But, that ratio only applies to the box. The pitman arm, idler arm, and the steering arm lengths can change the overall steering ratio.
