I spent some time working on the Vortec 454 swap into my '86. Got the mounting bracket issue figured out. Had to use the engine 'cups' and mounts from the '77 big block truck I parted out.
I also installed some DJM 3" drop tubular control arms that I've had laying around the garage for 4 years. Unfortunately I can't roll the truck out of the shop to get a good picture of it.
