I plasma cut this and tested it on a few motors at work today. I'll post a pic of the actual item shortly.
Should fit small and big and Holley 2V, spread and square 4V, GM TBI, as well as Chevy LS lifter valley.
Dimensions indicated in the plans, also included a 1:1 print-and-glue "hammer-friendly" page for those who don't want to measure.
Let me know if any holes are off; you guys are the first to use these.
Cheers.
