yo, I have some gt40p's im porting and putting springs on, and eventually throwing on the pile of metal I call a mustang. I was at mustangs unlimited in the Atl and the guy told me I couldnt use my bcam with my 1.72rr's? They worked before with maxxed out e7's I mean everything that could have been done was done!! So I dont know what to think here, Id like to put em on but if they arnt matched for this cam ill just sell em and get some 1.6erz.
