Yeah I think I checked with that guy and he said he would rather get rid of them locally because he doesnt want to deal with shipping them. That would be sweet if your interested in helping. Let me know.
Don't forget that unless you get the Cobra GT40s you will have a larger combustion chamber and lower compression unless you have the heads milled. Also, the non-Cobra GT40s are not drilled for the thermactor system although the internal ports are cast in.
the lower compression won't be enough to effect anything. my bro has a gt40 explorer motor with a tfs1 and mine a gt40p explorer motor, and his makes some serious power
