What Holley pump?

If you're talking about their "Mid mount" accessory kit, it adds an inch or more to the front of the engine above and beyond the truck accessories, so not exactly great for fitment.

 

Posted right after you posted 101 not sure about that one.

 

Holley
22-101

 

The Holley 22-100 pump? Fairly sure you can get an after market version or AC Delco for much less.

 

AC Delco pump is a little cheaper not much at least not on Rock auto. This looks like the late model Camaro pump. Holley says it will work with truck accessories.

 

The 101 has the Holley name on it and may be a one-off product...may not be available on the aftermarket. I decided use the vette damper and wp for the extra clearance.

 

That's just an LS2 pump.

 

Good to know.

 

While it is just an LS2 waterpump, the fit and finish on Holley's products in my experience has been excellent. Normally I'd say ACD or nothin' especially compared to the ebay waterpump (don't do it they're a trap!). In this case if you can get the Holley for less than a genuine ACD, I wouldn't be afraid to buy it myself.

 

This pump will not work with the truck
accessories. You have to use the Camaro alternator/ power steering pump bracket. This reverses the alt on the bottom and the pump to the top. Would this give me more room next to the steering box?

 

Its the same as the LS3 pump from a 2010 Camaro 6.2l. You have to cut your alternator bracket, relocate the idler pulley and buy a Camaro tensioner. The spacing is correct for truck accessories.

 

Did I do this wrong? I mounted the LS3 water pump, trimmed the triangular piece from the top of the truck alt/ps bracket, and <tried> to mount the bracket, but the p/s pump pulley runs smack into the steering box!
It looked good in the pictures, with the engine on a stand, but not in the truck...

Ideas?

 

What accessories/kit are you running @oldfogey47 ? Also what engine mounts?

There is a Ford E150 pulley that is smaller diameter that will swap onto the GM P/S pumps. I'll have to dig up the application/part number, but I used it on a friend's truck when we thought we had clearance issues to the steering box. Ended up we were wrong, but it's an option others have used before.

 

I have not pressed it on yet to verify but I have a 12569456 pulley I'm planning on using if I need to. Its all metal and has bolt access holes for the pump.

I came back to say I tried to press on the 12569456 pulley but the offset is too much. It will not work with the truck accessories. Hopefully that will save someone the trouble of buying one and trying it.

I'm using Current Performance Wiring motor mounts. No "real" accessories, just P/S (no A/C).

I know I can't be the only person to "discover" this little problem. And, I don't want to use some elaborate March or Holley drive setup because … TOO $$$ ...
You can see the problem in the pics, and a pic of how nice it looks (on the engine stand).

Krazy Ken...
I'll see if that may be the answer... what is it off of? 12569456 doesn't work in a search.
WAIT! I found it ("Replaces Original (OE) Part #: 12569456, 19258492 Power Steering Pump Pulley (300-137) by Dorman"} ...Dorman 300-137 is it - looks like about $30. Outside dia: 5.224 In.

I almost ordered the dorman 300-137 until I found the used one on ebay for a decent price. I'm not to the point in my swap where im ready to bolt on accessories so I can't personally verify the fitment. They list the specifications of the pulleys here though.

Edit: I copy and pasted the info here in case the link ever gets broken. Take all the specs with a grain of salt as it's not my information. Also pay attention to the pulley ID as the corvette PS pumps use a slightly smaller shaft.

Keep in mind, if you change the diameter of your PS pulley, your going to need to get a different length serpentine belt.

 

smaller pulley will speed up the pump too
at higher RPMs it may foam

 

I have a smaller Camaro pulley on my pump and it's been fine.

 

When I ask about accessories I'm asking what vehicle or manufacturer the brackets are from, truck, Corvette, Camaro, Holley, etc. If I'm not mistaken you have the truck accessories.

Smaller pulley definitely looks to be your answer, but also see if you can't move the engine over more toward the passenger side. Won't help with the pulley, but might open up clearance for other parts.

 

There has been more than one build thread that I have read that used the smaller pulley for clearance with no problems and a cooler is a good idea plus synthetic fluid wouldn't hurt either.
