Chev is 1.25" between holes
3" from top to bottom on a single pulley
Pump bolt up face is approx 2" 9/16 across
These are short pump measurements
Go measure a Holden... those bolt spacings looks alot wider in those 2 pics above to me

I know people have been crying about the price.
I had a gilmer setup for a few years and ill just give a comparison from my experience, for the same time iv had these billet muilti rib pulleys, I would have been through 2 possible 3 gilmer belts, 2 complete sets of gilmer pulleys as they wear out, and due to the track work I had to slow the water pump speed down which required 2 different sets of gilmer pulleys, small size and large size, so I could use a small crank pulley and large water pump pulley.
so to me these billet pulleys were worth it, I can also get replacement belts easier and cheaper.
quality costs money.
anyone priced a QUALITY set of pulleys for a chev or ford engine, I have and there not cheap.

Do you have to run a belt tensioner with the serpentine set up?
Cant it be tightend via the alternator like a gilmer or v belt?

The reason serpentine belts have become so widely used by the OEMs is not because they are better, it's just that they are more compact when you have multiple accessories to drive. Back when most cars only had an alternator and fan/waterpump, a single vee belt was fine. Now that most cars have an alternator, fan, power steering and aircon it's much simpler and tidier to run them all from a single serpentine belt.
But for an old car with only the alternator and fan to drive, a single vee belt with steel pulleys is probably the lightest, cheapest and most reliable setup.

Theoretically you could, but with a flat belt like a serpentine or a gilmer everything has to be very solidly and squarely mounted or the belt will shred. It's usually easier to solidly mount the alternator and run an idler.

You can use the standard slide adjuster.
I changed this to a double rosé jointed link because I was worried about reliability when racing. Worried the slider would move.
Also made adjusting belt easier.
