Looks like there are several LT1 intake mods going out there. Opti Spark to dist with several paths taken from plugging holes to major milling of material and adding plate along with dist mount shim being welded in. Others are modifying LT1 intake to fit SBC first gen. Wow. There are a few photos of modded intakes out there. Some are very well done; others not so much for looks but probably work fine. Neat stuff for sure!
