Distance from the back of the mount to thru-bolt centerline is 1.75. Worked great on my 72 big block chevy nova. By Eschwentke on January 19, 2022. Easy installation and fit great. Yes, I recommend this product.Firmer than OEM, so you feel the engine more. By Willy on December 01, 2021.
Most of the OEM listings were for the'clamshell' style where the big part is bolted to the frame, with just tabs on the engine. Most engine swaps use this style, where the frame just has a through-bolt mount. By dlschoo on March 17, 2021.SBC in off road vehicle - no tearing of original rubber mounts anymore. By Bush Jones on January 04, 2020. Used in the install of a Blown SBC in a Hot Rod. I have never had one of these mounts fail. Unlike standard rubber ones that pull apart if you even think about putting horsepower through them. By Orlando on April 25, 2019. Durability is so far unknown but they do seem very well built. None noticed as of yet. Same quality as more expensive brands. Related Items / Suggested Parts. Chevy Rubber Motor Mounts, 4.3L V6/ Small Block/ Big Block V8.
