I don't mean to hijack the thread, but I have a question too. I have a .030 400 block that was setup for TRW L2440F pistons 4.150 bore and .0025 clearance. I want to use a 455 crank cut to fit the block w/ TRW L2359F pistons that require 4.151 bore and .003 clearnace. Can I use the fill in my block if I need to rehone for the extra clearances?
