OK I have a strange setup.. and can't find clarity ANYWHERE where I fit..
I have a 1974 Opel Manta with a 2004 Chevy Colorado 2.8L transplanted into it.
Obviously Opel is owned by GM and GM Owns Chevy.. but thats where it stops with ANY relationship this motor has with the car. Heck the motor wasnt even designed until the late 90s early 00s' so any chance it was ever in this chassis are nil.
Is there even a class I can be in..?
