1968 L88 cars

[L88]

Hi, sorry about not replying right away. I don't know what happened to the original car, I bought the short block about 5 years ago and have slowly rounded up all of the correct dated parts to complete it. I pretty much have everything. There is no serial number that I could find on the front of the block (right in front of the head)or at the rear of the block. Maybe Chevy forgot to stamp it. The block is stamped with T0629IT (IT standing for L88). The block casting number is 3935439 with a date of E38. It is a 4 bolt main (and was originally because it has the bigger holes by the oil pump) and has high perf cast into the block as well. Any help is appreciated.
