Looking for options to put on a stroked small block in a duster to replace a set of TTI's .

Yes sir, it's a full 1 tenth and 1.5mph gain over tti's. 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.
