I have a LT1 that I would like to trade for a 400/406. If you have one, but would not trade let me know what you want for it and I will consider that too.
Here are the details on the LT1. It is a long block from a 94 Impalla SS. It uses the newer style vented opti. I have all of the wiring, computer, intake, throttle body, maf sensor, and accessory brackets from a 95 T/A. This is basically a 95 F body LT1 except it has Iron heads.

Thanks

Ben
