I'm going to try & view the motor tom. i was also told the XCD is on the front & back of the pass. valve cover printed on a 1/2 inch X 3 inch piece of paper & that it's old but very clear & still stuck to the valve cover very well.I will personally pull all dates & take photos. 427 KING what do you think the XCD at the end of your Suffix code stands for?

I went ahead & bought it. it has like a little white kinda mold & pretty surface rusted. I'm going to pull the bellhousing & mount it to a stand & then pull the pan & document everything.I found out that the part # is for 70 Lt1 Assembly & that the XCD is for high performance crate motor. I posted at Nasty Z also. What do you guy's think ????

Looks like a 283, you better give that to me....

Take lots of pics of the markings and codes, look on both sides of the block for the CTB or CTC written in yellow, upside down.
