MSD distributor 408 stroker

That is the same part number MSD Dist. I have in my 416. Did you compare the length to the old one? Or is this a new build? I assume you installed the oil pump drive? Was the oil pump drive bushing installed in the block? Need more information.
Good morning, so all we did was pull the old (billet style but cheap looking) distributor and drop the new one in per instructions. We did check the shafts against each other and the MSD is shorter. Here’s a photo of the receipt for the motor. I don’t have access to the old distributor as I am at work presently. Let me know if you would like that info later. Hambony.
