is this a magnum engine? need to know by tomorrow noon.

Not without crawling under it and taking off the starter and access cover and using a prybar on the ring gear.

Just noticed we all missed a question on the first post. The transmission used is a A518. It's basically a 727 with OD.

What year did they start using the 46RE's?? & I thought the A518 was basically a 904 w/overdrive??
