LOL no offense but i dont see a Grand Prix GT(205HP)stock, gettin much faster than a Grand Prix GTP(240HP)stock.The reason being that they are way different in engines and trannys.I got 2 GTP's both stock and they are fast and have not found a GT,or even a Mustang GT for that matter, to even run close to me or any other GTP's.the L67 is one tough,strong,reliable and undefiable engine up against the L32 in my book. which does not have the components that are really racing material built for the drive hard and severe torque that the L67 with the m90 eaton blower puts out.so goodluck man.that is my opinion and i am stickin to it lol.
