The problem with the 2-bolt block is not the fact that it is 2 bolt but the way ford designed the main webbing. The blocks have the oil hole from the camshaft to the mains right down the middle of the block. This is weak erea of the block[I][/i]
There you go!!!! It's right there. By virtue of the fact that ALL 27's have the same hole from the cam to the main they have that sam weakness!!!!!!!!!!!!!
Use the 2 bolts block with main studs and balance everyhting good and you will have no problems. Keith
From Keith you will have no problems with main studs. Where does he mention a 4 bolted 27 main? It's right there try to understand and reasearch the way the blocks are oiled before you go off again
