Just curious what type of "Doom & Gloom" worries these people have. DalePs 67 Mustang has gone mid 9s, my Fairmont high 9s, my SB 85 Mustang low 10s, and my buddys 64 Comet has gone high 9s, all with solid stock type motor mounts, also all sticks, normally dropping the clutch at 6000+ RPM, with no issues. All also have stock front chassis. On a full tube chassis car, the motor plate would help tie the front frame rails together, not sure how much that would apply with stock sheet metal frame rails and shock towers. I suppose that eliminating the side mounts would free up room for custom made headers, but with the stock chassis and steering box, doubtful most people would elect to spend a bunch of money and time to have custom headers made, when much cheaper "off the shelf" headers are available. Also with a front motor plate, a mid plate should really be employed, which could be a challenge when the stock firewall and frame rails are retained.
