Re: [Amc-list] 6 cyl. to V8 swap

The first thing to consider would be "subframe connectors" as Bart suggested. These connect the rear of the front chassis rails to the front of the rear chassis rails. Of course the rails are integrated into the floor structure, they aren't subframes as some GM cars use. These can be made with rectangular tubing or 18 gauge sheet metal shaped in a channel and welded to the floor. The second thing is to weld/rivet/screw a piece of 18 gauge steel to the braces behind the rear seat back. The 69 SC/Rambler had stronger bracing in that area -- either thicker metal or doubled braces. A solid sheet firmly fastened in will do the same AND provide a firewall between the rear and passenger compartment -- just in case you want to trunk mount the battery, a fuel cell, nitrous bottle, or just carry a spare can of gas.

So what kind of reinforcement would need to be done so I would not  
have trouble with the body twisting?
