All,

I have looked through a lot of pulley posts but still am confused. Getting ready to drop in the new mill.

My setup is a 77 LA 360 Ex Balanced with a Milodon High Flow water pump and a later lighter factory degreed crank balancer. No Air cond. Going with Champion Rad with twin electrical fans.

I have the single groove water pump pulley and a 2 groove Crank pulley p/n 36143_78. I mocked up the 2 and the is a lot of misalignment by a half a groove.

Q1 - What/How do I need to setup the WP Pulley? With no fan what parts are used? I assume the spacer is not used? It is 1.860 tall? The pulley is 2.25 tall and 6 inch in dia.

Q2 - What/How do I need to setup the Crank Pulley. It is a 36143-78 and is 3.25 tall and 7.5 inch in diameter on the big groove.

Q3 - What is the Crank Pulley bolt size, Mancini has some but was looking for a differnet source. I have some that fit but do not appear to be the right pitch etc. but I could be wrong.

Thanks,

Marion
 
Non A/C water pump pulley should be
29518-36 for a factory set up. You said you had non factory parts so this could change? But I just did all the pulleys on the same engine. So I knew the number.
 
I see that there are some water pump pulley spacers.

Should I space out the pulley approx. 3/8th?

My pulley ends in a 28 but I cannot make out the rest.

I'm going to use the power master factoty alt, and power steering too.

Do not space it out. Use the 29518-36 pulley and you will be all set. I found mine at a swap meet. Try Ebay or google part # 29518-36 pulley. It will pop up.
