I forgot to mention this earlier in the threads ,but I when bought this car it was with the understanding that the engine block was cracked. Even before the car arrived here from N.Y. I was in search of a 273 block to replace the seemingly cracked block. The guy I bought the car from was getting water in the oil and thought it was blown head gaskets, so he removed the heads, had them shaved ,new guides and seals installed, and a 3 angle valve job done. Happy as a clam he reinstalled these practically new heads with new gaskets and filled up the radiator.Thinking he`d found the source of the problem and fixed it, he changed the oil and proceeded to crank it up. Instead of the big smile of a proud father he was horrorfied to find water in the oil again. Disgusted he took the car to his local mechanic. I don`t know what the mechanic did, but his diagnosis was that the block was cracked. I took his word for it when I bought the car, so I sought out a 273 shortblock and lo and behold ,a member had one here in the car parts for sale section. After a talk with Bob (the guy with the shortblock)who was looking to put a 340 in place of his 273, we worked out a deal and the shortblock was removed from his B`cuda ,palleted ,and sent to a terminal here in Va. where I picked it up. It was $200.00 and about $140.00 in shipping from Michigan to Va.. Bob had just rebuilt this shortblock and had installed .030 over pistons with Chromo rings,new cam,rod, and main bearings. As a bonus this block was cast on the exact same day as the original 4-17-67. What`s the odds of that happening? I ordered new water,fuel, and oil pumps and installed them along with the recently reworked heads. A new vintage Edelbrock intake was compliments of Ebay and Bob served up a new/used Eddy 500 carb and a timing cover. While this was in the works, I pulled the engine and couldn`t find any sign of a cracked block. What I did find was a timing cover that had corroded so bad that the water pump was pumping directly into the timing chain area. Bingo! The"cracked block" was found. So in the course of about one month all of these things transpired to put together one nearly completely rebuilt engine and find out the truth about the original engine.
