Need 390 double crank pulley

[yellercat]

Like to source a good, that is usable, double crank pulley for the 390 new build that is ready to install.
Please drop me a PM if you can help. Have some small engine bits for trade if that works, too.

If it’s going to matter to you, you might want to let folks know what year 390 you’re working on, or which harmonic dampener you have - Ford changed the FE lower pulley bolt pattern starting in the 1968 model year. ‘68 & later is a slightly larger bolt circle pattern, ‘58-67 is a slightly smaller circle. The pulley bolt holes can be modified, or sometimes the other pattern drilled, but just something to be aware of, especially if your hoping things line up easily. Bolt on lower crank pulleys for the ‘58-‘67 dampeners can be a little harder to find.

mustangtek.com is a great resource to assist in identifying the pulley that you are looking for.

To expand on what Kevin said, the 67 and earlier dampers are much narrower, and depending on the year, will have 1 grove built into the outer ring. The 68 and later dampers are about an inch wide (thick), and do not have an integral pulley, any pulley is bolted on.

Learning every day  with you guys! Thank you all  for the replies; I was not aware of these differences in the dampers.
Will double check my engine and verify that I have the later style.
