MSD 85561 Distributor

Compatible with Small and Big Block Chevy® equipped with tall deck blocks or decked heads. This product is not created or sold by Chevy®. Must be used with an MSD 6, 7 or 8-series ignition.;

If you have a slightly taller block or have decked the heads, the distance between the distributor mounting pad and the cam gear/oil pump drive may be different. MSD offers these Distributor with an adjustable slip collar with 1.5 in. of adjustment so you can be sure the distributor is installed correctly.

The distributor shares the same features of the standard Pro-Billet Chevrolet model including a ball bearing guide, long sintered lower bushing and an oil seal. To reluctor the MSD Ignition a maintenance-free magnetic pick-up is secured in the billet base of the distributor. Just above this pick-up assembly is an adjustable mechanical advance assembly.;
