Hi Jeff, yes, welcome! I'm a member of the Western Washington Firebird Club and also involved in the NW Legends GTO's... I know of a few people in the area who have some sprint stuff, and may know some one who at least had an extra sprint motor etc...
I'll check around to see what I can find. I'm kind of partial to the Sprint-6 cars myself as that was my first car. a 67 Sprint-6.
Let me know where you are at and get in touch with me and we can go from there. I'm also friends with Quenton & Brent who started Primatech... so there are LOTS of possibilities!
