my setup is a lt4 hotcam 355 9.7 to 1 compression ported 083 heads with 2.02/1.60`s, and holley stealth ram, 700r4 fully built with 3000 stall and 3.23 gear ratio. for some reason first and second gear pull like i think they should but as soon as i hit third it feels like i lose 100hp and realy sluggish. ive had a few shops take a ride in it and i get all different oppinions. my guess is the gear ratio and stall matchup is wrong for the cam, can this be or may i have other issues????
