Looks great. Very similar to mine
Made one at a previous employer. We made a motor mount support that saddles the main frame so you can slide it forwards or backwards. Make the vertical supports for the motor mounts height and width adjustable (jackscrews and slotted mounts) and it will fit anything.I made it for my bbc. I am planning on making an adjustable mount for a mid plate. So I guess you could make a custom front and mid plate for any combo
