  • Engine Transmission Swap Gen 3 Stock Mechanical Clutch Linkage
    To use the stock mechanical clutch linkage when swapping in a Gen III/IV engine means placing the new engine in the correct position in relation to the bellhousing mounting face.

By using the McLeod 0.400-inch-taller flywheel, the clutch disc hub is positioned farther back on the input shaft splines.
