Different mount system on the Bonnie...no dogbones, but the front "hockey puck" mount is notorious for splitting if any serious power is applied to it. Many different mods have been tried, but the most widely used is a solid rubber block with a thru-bolt for strength.

The engine bay looks roomy now with the upper rad support off, but it does have slightly more room than the GP...I would absolutely LOVE to drop the LS4 mill in there...plenty enough space and that sweet V8 growl!
