here is my take on this swap noise ANY engine used to power the car is ok as it will keep one more away from the crusher many swaps I have seem are done poorly, so factory style swaps are easier my moror is amc but my valves were designed for a chevy ,my rockers for a ford my push rod for a chevy and I got a modified chevy HEI ignition my trans was made for a cobra(ford) my scattershield for a chevy and my rear end is a ford 9" so lets stop the hard times and let everyone live and remember their piece of AMC driving as it may be I bought my first Gremlin in 72 so I aint no newbie to this I personally perfer a AMC motor just because-- just remenber the more that get crushed the harder it is to find usable parts
