72 big block mounts?

[GASWAGON]

I took these out of a 72 rolling chassis I bought. Are these big block mounts?
The truck had a 454 in it but P.O. installed it in place of the small block. Any ideas? Thanks

Those are not the factory 72 only big block mounts.. they are 73 up mounts which will work in the 72's by drilling a couple of holes..

Those are the same mounts we used out of a '73 C-20 when we put the 454 in my '71.

We did have to drill some holes in order to use them since when the engine was mated to the transmission and settled into the frame had no holes that matched.

It turned out good though and allowed the right distance from the fan clutch and radiator. There also was plenty of room at the back between the valve covers and firewall.
