I think my cam is .600+ lift. I don't know at what lift BTR believes that the vavle springs need to be changed every year, but mine is one step down from that.

Gotcha. I was just trying to guess how much steam my 468 is making.
How much did those heads set you back?
Can't recall the exact number, we did some horse tradin for the cnc time for the port work. I wrote the program to cut the offset push rod holes for his CNC 5 axis mill. I'd love to get the heads flowed one day. I spent a lot of time on the short turn radius and opening the "throat" below the vavle seats.
The water pump application is a 82 to 85 4.3 V6 diesel, only available in cast iron. I used a Ford 351 truck crank pulley drilled to the Olds crank bolt pattern.
This is the GMB reverse rotation water pump I was refering to.

As nice as that setup is and as good of an update as I guess it is, it sure does cover up an otherwise beautiful engine. I'll stick with V-belts on my old engines, unless it's driving a supercharger. I've never had an issue with V-belts.
Just one man's opinion. And again, it is a very nice fabrication effort that shows talent.

The Olds V belt setup is kind of shitty with spacers all over the place. I just ordered one of these while Flowkooler still has them. Putting this on the 374 Olds stroker.

I ordered a Flowkooler for my Caddy. Beautiful impeller. It made zero difference in temperature over the GMB solid impeller that it replaced. The GMB was $34. The Flowkooler was $135. I’ll use the GMB on my ‘57 F100 Caddy swap so it wasn’t a total waste.
