Marlin;

The Mark Donohue edition trans am Javelins are not the same as the TransAm Javelins, these red/white/blue cars came with 390cid engines and used an adjustable rear wing instead of a spoiler( '68, '69 Javelins campaigned in SCCA's TransAmerica sedan class racing used these). The Mark Donohue trans am edition used both 390 and 360 cid engines. However the 360 cid block was special and different in internal construction for use to destroke down to 305 ci limit for racing. Mark Donohue Javelins were built later during the 1970 model year and only this special design block tells you it's a Donohue edition, but if a Donohue Javelin was ordered with a 390 cid, it can't be destinguished from any other Go Pak optioned Javelin that has had a spoiler added.
