174/177 supercharged small block, where to start?

I started to do some minor mock up today starting with the pulleys. Because I have an aftermarket set of billet aluminum pulleys, I needed to machine the center register on my crank pulley roughly .010" of an inch for it to fit over the center register of the blower pulley spacer. Luckily, my girlfriends brother is a machinist, and has a lathe in his garage. :)





Here you can see the center register does not fit inside the crank pulley.



So on the lathe it goes.





Now it all fits together nicely.





Here it is bolted on:



Now the next problem. In the already very tight engine compartment, my mechanical clutch fan blades hits the blower pulley! LOL





This shows you I cannot space my fan out any further, as I am already dangerously close to the aftermarket aluminum radiator.



SO.....I guess my current plan is to switch to a dual electric fan setup, which will be out of the way of the blower pulley....I will update the thread when i figure that out and get some fans mounted....

...whenever the hell that'll be....lol
