We are in the process of stuffing a 351 stroker in a 88 coupe with a AOD behind it .. We are looking for input on headers ... Hedman makes a set for the swap .. but notes C4 trans only for automatics and Hooker just says yes to automatics .. Hooker's tech lines says they'll fit .. I'm looking for some real live feed back .. And I've only found Hedman & Hooker with listings for the swap .. anyone know of others ?
