OK, here goes. I contacted the owner and discovered the following info: Vette is a 68 Coupe w/L71 & M21 tranny. Numbers and photos owner provided indicates this as an all original car. He has the original tri-power set up in storage. Block is 321 with IR suffix and was in car at time of fire along with M21. I'm sorry for all the confusion, just was going by Fire Marshal's report of 69 L88.
