Cast iron 5.3 blocks
Said the largest they would go and it be safe for racing is 3.880 bore. And that is with sonic checking the block.
Which, if I combine that with a 4 inch crank will give me a 6.2L engine.
Now to go spend $900 on a set of Wiseco forged pistons, $500 for Callies Compstar forged H-beam rods, and $915 for a forged 4 inch Eagle crank.
