I have the Buick V-6 distributor, I bought it to make the switch but changed my wmnd, If you need one I don't mind selling it. $75.00 plus shipping

Will the Holley 500 #4412 carb and #1937 adapter plate work on my 401M?
It currently has the Stromberg.

Also planning on doing the HEI conversion with the EvenFire Buick V6 HEI distributor. As far as the bushing needed, I am going to check with WE7X to see if he still has any in stock. Or, we can build our own quite easily once I know the specs.

Thanks in advance for any info,
Wade
