1966 389 numbers
Ok - I'm new to the Forum, but look forward to learning and sharing knowledge. I've been a British car guy for a while (MGA, MGBGT, TR3, Jaguar(350engine), AH Sprite - for autocrossing and it's time for a change. Been a while since I played with real American muscle and can't wait to dig in. Fact is I used to be a Ford fan (I know...) 1966 Mustang, '69 Cobra Jet.
The wife said - let's build a real car - so..picked up a 1966 LeMans convertible as the next project. Not sure how the Forum feels about GTO clones (may have an idea though), but my wife wants it, so that's where this project will go.
Hence, my question.
I picked up a 389 engine #9778789 that according to my research is a 1966 - right for the year of the car.
It has 092 heads (correct fro the GTO)
There is a number stamped on the right front - looks like 576488 YC
I believe the YC is a 290hp engine for an automatic-Is the difference between the 290 and 325/333hp the cam or cam and carburation? Or is there some other variable? Any idea what the 567488 might mean?
For now I plan to stay with the 2 speed automatic, as archaic as it sounds. Anybody have any experience with the 2 speed/389 combo? I would prefer a 4 speed, but I'm not ready to hang new pedals, etc.
I hope to make it a frame off (or close) project. Stay tuned for updates.
Thanks for any comments back.
