No worries man. Those specs are very close to what I was thinking were being used. Standard port location small blocks tend to work well with the 4-5 degrees split 260-270 @0.050 range without needing to spin it past 7000 rpm. Considering the combination works very well it helps to justify the case along with all the other details of course. Out of curiosity what are the cam specs for the 422 in your car?
