That's another reason I'm using it; I'm trying to keep the car under 3000lbs. I have the motor set back roughly 2.5" for better weight distribution as well. Notching the firewall is easy, since I'm making a custom tunnel anyway.
Yes; I still have all of the OHC-Pontiac engines for sale; I'm out of the country at the moment, but we could work something out when I (crossed fingers) get back in a month. They are all in NE FL.
