I've got a rebuilt 1964 413 shortblock to install in my 64 Fury this summer. I wanted to put 452 heads on it, but after checking the piston height, I'm sure about it. I used a straight edge and feeler gage , the piston was about .085 down in the hole. Are these possible truck pistons? The 413 is bored out .030. Aren't the 413 pistons hard to find? Any recommendations on pistons? Would 426 pistons be easier to find? ( block bored out .060) Gary -- [Non-text portions of this message have been removed] ---- Please address private mail -- mail of interest to only one person -- directly to that person.
