440 Crank pulley

[Mike Miller]

My Crank pulley does not seem to fit..it is a 4 groove, 7 1/4 inch diameter that when using a 5 3/4 diameter water pump pulley barely has enough room to slip the alternator belt between the two.
I do not have a/c.. just power steering. The pulley(s) are too far back and i will shim them forward, just wondering if this setup is normal for a 440.i have seen where it was said that motor home engines used this setup..do any of you have a pulley like this on your big block or should it be a 2 groove ?? All 4 are the same diameter .

You have a mismatch of pulleys. You will need non-a/c crank and water pump pulleys for starters and go from there. Look here or 440 source for pulley information. Products: Pulleys - Bouchillon Performance Engineering

More info. Click and read on each one for more information. I would start with a non a/c 2 groove crank pulley and go from there. Pulleys & Belts-440 Source

Do you have a steel crank damper or a cast.
As I recall they take different pulleys.
You should find correct 2 row pulley for 20 to 25
and it would be a lot cleaner than shims.
