looking for a 4.3 vortec

I am looking for a 4.3 V-6 Vortec that is a runner. Do not care for the throttle body injection or the multi-port injection, just the block and internals. I plan on putting a carburetor on. If anyone has one please let me know. I love the torque of a 4.3 and as far as I know no one has put one in a Fiero. Thanks
