Under the heading of this is why I have a shed full of parts from cars that have long gone, because I was working in someone else’s warehouse space I overly disposed of parts from the old SBC. The new crate engine is in and I need to connect everything now but as it turns out I had a extra long crank pulley set up that I’m having trouble finding a replacement for. You think these things will be everywhere but I am a bit stumped.

The old engine also had a long water pump, so that’s what I ordered when I replaced with this one for a new one, but I’m obviously nowhere close on alignment here.

Well first off the old one is a 3 groove and the new is 2. I dont remember if that front pulley is a separate piece or if it's al1 piece(the 3 groove pulley)
Good morning Gentlemen , hope you both are well and staying safe.

@peesalot - I ordered another three groove pulley but when I measured I don’t think it’s going to give me the additional reach that I need, that said I can always return it, and the two groove is clearly not getting it done. Thanks for the eyes on it .

@bikersmurf - To be honest I hadn’t really thought about making that conversion, the old school pully system worked fine for last year’s adventure and I thought I was going to be “keeping it simple by just transferring everything over, to be honest I hadn’t really thought about making that conversion, the old-school pulley system worked fine for last year‘s adventure and I thought I was going to be “keeping it simple “by just transferring everything over” well that didn’t work out. Ooof

As you must know, when Chevy used the short water pump, the alternator sat out beside the cylinder head, and there was a matching set of pulleys for the short water pump. With the long water pump the alternator sat in front of the cylinder head, again with a matching set of pulleys. Kinda sounds to me like you are trying to mix pulleys ???
It looks like even if you had the proper crank pulley, the alt and p/s pump will be fighting for the same groove. I think your ps pump mounted too far forward. You might need a different bracket. The stk crank pulley is 1 piece. When I get a chance I'll look l To see if I have a spare pulley.
Good morning and thanks for the responses.

@Downey - thanks for the reminder, what is weird is that I am using the same set up as before as I had for the long neck.

@pb4ugo - very helpful shot. I can adjust the location of the power steering pump to match the rest of the set up, good catch.

@peesalot - picked up a quality three grove pulley to try today.

I realized I have one more thing going on here - I changed the brand/sourcing of the crank damper and I wonder if that is what is making the difference in where everything is locating?

Thanks for all of the responses - hope everyone has had a good weekend so far.
Back in business - I think anyway! Double grove water pump and three grove crank pulley.

Thanks for the help.
