Will work with GM big block motors. Will not work with factory engine pads. The new mounts are made entirely from sheet metal and are made here in the USA. The factory big block mounts are next to impossible to find, and these are way more attractive than the stock mounts anyway. These will work with big block engines only and will not work with factory engine pads.
Works with BIG BLOCK engines only. Orders placed Friday and through the weekend will be processed Monday (excluding Holidays). If you receive an item that is damaged or defective or missing components, please notify us within 3 days of receipt.
