Hi Max and Ian,
Ian's correct that's a GPA engine going by the decription. I would be interested in it Max if you would be willing to sell it

. Im in the same boat - I sure don't need to be collecting more but what the hell it's a difficult addiction to quit! I have a GPA and as yet don't have a correct GPA motor. My GPA is 5333 and it's motor is in Trevor Boyles GPA so I have little hope of trying to talk Trevor into doning an engine swap!

.
It never ceases to amaze me that there's still lot's of parts out there just waiting to be found or recognised.
Regards,
Brett.
