The code was something like D2OE AB from what the decode thing says d would be decade 1970's 2 being 72 O being a fairlane or torino AB being interceptor heads. The original engine was a 302 in it and it was pulled out years back. the heads gave a similar code D20E AB or BA cant remember, as far as we know though one person remembers the orig engine being pulled and swears the motor I had came of a fairlane so its very hard to say what the deal is. And reallly the codes may lie but Im goin by what they said, I will leave yall with the website when I have more time to post. As for now its up in the air, but one thing is certain my transmission is an FMX not a bad tranny durable. Well just wanted to drop a line so yall didnt think I was full of BS. LATER I think drg may be right it was a police issued engine.
