How to Part 1: LS Swap using Buick Olds Pontiac (BOP ) Turbo th2004r, 350, 400

For my brothers 1977 Cutlass we are going to use his existing BOP TH400 thats in the car. We pulled it out so I can replace all the gaskets and seals. We are also Installing a 3600 stall converter as well. I ran into 2 issues and I made this video to highlight these issues as well as provide a solution to the problem.
1.) The converter snout combined with the crank adapter bushing creates a fitment issue. fully installed the converter flange will not lay flat on the flex plate surface. It may not in fact be an issue If I can install bushings between flexplate and converter but I wont know until I bolt the engine to the trans.
2.) The engine to trans adapter place requires me to drill a hole in the top of the adapter to accommodate for the lack of bellhousing bolt on the right side. Also there is a nut welded to the plate which comes in contact a boss on the back of the block. I may need to weld a stud onto the the plate but again I wont know until I pull the flexplate off to check fitment. Next video. Stay tuned.
