    I'd have to ask why you want this swap?
    For the trouble it'll take you wont be making a big difference in horsepower or mileage.
    If its because the old engine package is high mileage you might want to look at City Motors in Dallas for a remanufactured engine/trans, unless your getting the new eng/trans real cheap they may have a better deal for you on remanufactured.

    The Gen-III motors are about 1,000,000 % better engine than the old Small Block Chevy.

    I've already run into issues with Gen III motors and I cant say I share your opinion. Besides theres still many more parts available for hot rodding small blocks than there are Gen III's.
    And again the expense of a replacement Gen III is still high so you have to get a good price to make the swap worth while.
