    A leak that big & loud shouldn't be that hard to find, did you make sure all gasket surfaces are free of old gasket material? And when you tighten down ANY of the bolts holding your exhaust system together, tighten them a little at a time to ensure equal surface sealing ( especially those donut pieces of shit that I think all cars & trucks have) torque to specs. If none of this helps you need to check your exhaust all the way to the catalytic convertors, maybe damaged some of the exhaust tubing or connections during motor swap... good luck...:cool:
