This weekend I added some 351 numbers to the hood, from NPD, very nice quality, just a PITA to get centered.
Also added the Procomp Hood Scoop PCE106.1007. Iam still using the bottom part of the old air cleaner, the PO hacked it up to fit the Jegs brand distributor. I added a second set of threaded inserts that line up with new Procomp scoop's holes. I still think it's too tall, but it does not bind, so I guess I'll just go with it for now.
I have a Holley Sniper with a 1/4 spacer, and planning to run a Hyperspark Distributor. Hopefully the Procomp air clearer assembly will fit.
