Thanks!

I will pull the valve cover off later this week to search for a number. when i purchased this car , the guy that sold it to me said it was a copo motor from a 1969 camaro. He said the prior owner stroked it to 468 cubic inches. Question, will the head casting number tell me if it is a copo motor ? and if it is, is it more valuble then a reg 427 ?
Or are all 1969 427's copo motors ?

You are more likely to get that info by deciphering the code on the block deck. Those, I believe are the first set of numbers you posted. Double check them for accuracy. The letter/number code beginning with TO. The rest is going to be the vin # for the car that the engine originally came in. My reference material is strictly corvette, but after you re-check these numbers, put them back out here. Somebody here will help decipher. Go ahead and get those head castings and dates while you're in there.

Just my opinion, but if it's a COPO motor, I think it's value is increased only in it's original car...otherwise it's a 427 just like any other 427 made during that time period. It's desireable, but it would be a replacement engine in any car other than its original installation.

In '69, 427's were regular production options in Vettes and the full-size Impala bodies (though uncommon). Due to GM corporate rules at the time, anything over 400 cubic inches in Chevelles, Camaro's and Nova's would have been COPO installations.

True 'slinger, except maybe if that Camaro could be had or still existed. I never am sure just how limited COPO cars were, there seem to be as many of them for sale now as big block cars?????????
