Was wondering if anyone out there has put a Blower on a Chrysler 383. I'm mainly interested in reference dimensions as I'm currently blazing my own trail creating a manifold. The motor is currently in my T-Bucket topped with a six pack setup but I have a 6-71 I'de like to install. I plan to have a short block done to knock down the compression with a blower cam etc... Nobody really makes purpose built blower manifolds for 383-400 chryslers so hopefully I can figure this out and share. BDS, Dyers, etc. have manifolds however it appears they are just modified dual quad manifolds with an adapter welded on, which is what I have and plan on doing without forking over $1600 for just a manifold. I have measured the bottom of the blower and the top of the offy intake, and modeled up a "dry" run in Solidworks (just like they did in the 50's). I have the advantage of being able to lasercut a plate out of thinner steel to mock up before I buy a 1" plate of aluminum for the real deal (again, just like in the 50's). My question is, how do I get the currect length for the drive and position the blower on my adaper plate? I currently set it up so that the blower would be centered on the Offy intake. Can I just get a longer drive snout to accomodate? What is the proper method for measuring this? I do have access to a full mockup motor with balancer and heads installed. Once I have all that figured out I will worry about milling the top of the offy intake flat.
