Did the exact test on a stocker pump gas 408, 10.80 deal, and also on a mid 9.50 deal. Cutt the flanges and they come out of car with everything installed. Way easy to work with. Both combos gained the same by switching. Just my track results, others may vary. Thanks for the reply, this is exactly what i was looking for. Any chance you have any engine pics saved with these the hedman's on ? Al
