i can get you a GM opti at cost, since yours is vented, 240.02 shipped with new vac lines as well.
wires...you can get MSD 8.5's for 80 bucks, plugs...30-40 bucks, 10 bucks for coolant. if you have the original water pump on there...may as well spend the money and get a new one since its gotta come off anyways...and get a new belt, thats 40 bucks at the dealer, probably 20 at cost and can be shipped with the opti at the same time.
lemme know if you wanna get it, ill PM you the number. shipping is automatically UPS ground, but you can request faster shipping at your will and payment.

again, do the math. if you want help, formulas offer is cool, ill be glad to help you out too...the wires and plugs are more of a PITA than the opti is believe it or not.
