I ran the Weiand on my stroker and then switched to the AG, I gained some in the 60’, 330’ ,1/8, 1/4 ET and overall MPH. I’ll have to check my time slips to see. Around on the street honestly between blowing the tires off with either and hot rodding around I can’t say there was much if any seat of pants difference. Track? Yes (via time slips)
