O.K. i bought my lude out of fl to get a lude with no rust and i got the lude that is pictured for 1775 because it had some engine problems im thinking sounds like a blown head gasket
it had some mods like cams,intake,ehsuast,jacobs ignitions, dc header, wide throttle body, nos fuel pump, nitrous mastermind, and a chip in the ecu. This is me and my dads project car right now and we figured easy fix but we where both wrong. We pulled the old h23 and dis asslembeld it after we tested everything that would be an easy fix.
