Don't know how much frame mods were done to your truck, but on the tri5 cars a mount is available that bolts to the engine/transmission and to the original bell housing frame mounts. The engine/trans. needs to be supported in the center or on the side, I don't think the 265 had the side mounts. Check your block if it has the side mount bosses then you could put a aftermarket tubular engine mount and eliminate the front mount you have. The engine would then be mounted correctly, as it is now all of the weight is in the center and not supported.
