And I love your statment about "489 made 600+tq at 3400rpm with poor old peanuts"
208cc peanut port heads that dont flow over 235cfm at any lift can't even support 600tq, they really can't even support a 489 at 3400rpm. That statment is about the same as saying "my 383 with 150cc 881 heads made 500+tq at 3400rpm" C'mon man I'm not some flunkie you can't BS you way with.
well then the dyno lied.. some owned these, some play with "math"
