BUT..I was told by my mechanic..who has built many exotic an domestic cars...said so. He's in-love with my car...being a guy who owns and rebuilt a 1965 Mustang...... 1050 whp!!!!!! He's telling me what I should do to my Z to make it the best...of any Z ever built. Doubt I'll follow thru as I only have so much money
