Lol, I'm not now and I wasn't upset then, frustrated...yes. I understand you a little more clearly now let me try and be a little more clear, lol! I'm sure everyone (at least I think they do, lol!) in this forum know the SRT8 392 bore and stroke...I know I do. So I thought you were refering to the new 6.1 Apache heads and the old 6.1 Eagle heads (when you say new) because Chrysler never built a 392 vehicle with the 6.1 block. So that is the only difference between the crate and the stroker besides the SRT8 392 Apache heads but they all need the same clearances and the same valve releifs. My point was, no matter what engine whether is was a crate 392/426 motor or the STR8 392, they all need the same clearances. I'm not good at getting my point across in writing but I'm not the slightest bit angry, we're good brother! edit: BTW, I'm talking about the 392/426 alu Mopar only and not Arrington, PWR or anyone elses with multiple cam spec options. I can only imagine the BS I'll hear from someone else (not you) about this, lol!
