RE: Superchargers
my uncle has a 1979 power wagon with a 440. We pulled the blue block and dropped in a 68 orange.
We balanced and blue printed the motor...bored her .060 over....arias pistons...indy heads...the works...we then put a bds 671 blower on it (super charger...what? some people dont know)
the reason we swapped years is because the 75 and up 440 blocks were cast.....not forged. yeah i know....what the hell were they thinking??
because of this with the boost of the super charger....and some people are even going turbo now...it will eventually (sooner than later) blow a crack in the block.....its just to much compression. Many people argue with this so i went to a friend of mine at a dodge dealer (richmond dodge for the michigan people) and he told me that that rumor is very true....and after 78 (final year) they didnt even have wedged heads nomore.
so if youre going to make a blown motor of a 440....be sure its pre-75...the year of the motor is forged into the left bank i believe?? dunno check both sides, its there
