I am currently working on a numbers matching 1967 Firebird 400. I bought this project with the majority of the work done. the car was painted and the drive line was all rebuilt and sitting in the car. I have receipts for everything. After getting everything wired and plumbed we fired the car to break in the cam. After a few minutes of cam break in i noticed white milky foam coming out the dipstick tube. Yep, a considerable amount of water was getting in the oil. We pulled the engine and found about a 10" crack going from fore and aft along the main caps.
I have looked into getting it fixed, and have decided not to try it at this point. I will be keeping the original block, but i am going to build a new engine so we can enjoy this car. now for my question, I have a 1975 400 block, crank, rods, and pistons that are all machined and assembled. I have been researching this for about 2 weeks now, and i think that i can use this as a starting point and use all my parts from my 67 engine on this 75 block. Can anyone think of any road blocks i might run into.
Keep in mind that i understand this 75 block is not as strong as earlier blocks, but it will do for my mild street build. This car is going to be driven to ice cream shops, dinner and car shows. not raced.
