7075 aluminum has a higher tendency to crack since they are harder. at bcr we have had a few caps crack from guys really pushing the envelope over the years, but the percentage of caps that cracked vs the percentage that we produced is down around .1%
Nice! This motor is and was a fairly mild engine compared to most street/strip motors on here. Really, did I even need them??? I'm not concerned in the least about breaking a cap, I just liked the idea of "Lessing the load on a block"...... Hindsight........ should of went to a different shop that checked thickness in the first place. lesson learner!!! Thank again everyone
