What I can offer is a "sort of" valid comparison. Used legit stock 906 heads w/ a mild 440 combination to run 13.2 @ 103; switched to ported 452s (~ 270/200 @ .600"), along w/ changing from OEM-type 1.5 rockers to Crane 1.6 irons, and the car went 12.5 @ 109.

IMO, the combination you described will work better w/ a standard-size port than a Max Wedge, even if the MW nets more CFM. There's a lot of value from keeping the velocity up for 440 non-stroker combination, especially w/ limited stall speed.


Good points guys, thanks.
I knew that his current intake was a pretty good piece. And anything he can reuse is a big plus in his book.
I knew first hand that bigger isnt always better. I had a 493 with max ported 440-1's CNC that went 380 cfm+ with only 11.5:1 compression, it was a good runner anyways. I found out later that the same engine with a set of moderately ported SR's run faster in the same truck and drive train.. The 440-1's had MPH better, but the 60ft was worse...
This was in a 3300 lbs dakota. The E/T diff was just over a tenth, but the diff was there non the less.
