Well I was going to start a new post about the blocks. I had tested but I think the Info would be good here. I got some pics and sonic test numbers. I stated that the 78 was junk not really true now that I have the numbers in my hand. so here are the numbers if you click on the pics they should get bigger so you can read them. block 1 is a 70. block 2 is a 73 and block 3 is a 78. and when I got home I found other 71 block. I will take up to check.







.Now there is some talk about looking at the meat around the cam in the front. this might hold true by a wee little bit.









this last pic is the worst one I got for that and it is a block that been bore .030 over race in my car for years, was in a super gas car before that
