This listing is for a set of solid steel Chevy motor and chassis mounts.
It includes 2 (xpc) steel solid motor mounts & 2 (xpc) solid steel chassis pads for small block Chevy engines.
These solid mounts replace the stock-style rubber mounts and eliminate excessive engine movement in high performance applications which can result in torque loss and linkage binding. They also work great for custom chassis builds.
The motor mounts replace GM OEM part #3990914 used on most small block Chevy's from 1958-1972. They measures 2 1/2" inside the ears and 1-11/16" from back of mount to center of the bolt hole.
The solid steel chassis pads have the following specs.
- Mount centers: 2-5/16" x 5-1/16"
- Height at center is 2"
- Frame surface to mounting hole center is 1"
- Width at mounting sleeve is 2-3/8"
The chassis pads are direct replacement for the following.
- 1974-1981 Camaro & Firebird with 307 & 350
- 1973-1988 Chevelle, Malibu, Monte Carlo, & El Camino with 307, 350, 402, & 454
- 1973-1979 Nova with 307 & 350
- 1976-1990 Impala & Caprice with 307 & 350

Nice mount, engine brackets were too short and will not fit in my truck. Noticeably shorter than the stock one. I tried anyways though, the pictures are of the 2 sides. It’s close enough that I think it will work with some washers but I’m not sure if that’s a good idea. 😂

Didn’t line up at first but eventually got them to work

Mounting holes for engine mount bolt do not line up. One ear is bent wrong. The back hole is a half inch off. I’ve tried loosening all 6 other bolts and still doesn’t line up. So I’ll have to do some ajusting to make them work.
