Blueprinting... Educate the uneducated

Blueprinting an engine, simply means that the critical dimensions have been met. When you do this you would be crazy not to have recorded and kept the measurements. You do not have to change cylinder bore centers or angles. Your decks should be the same hight, and perpendicular to each other, rods, very close to the same lengths, position of the piston tops to the deck, bearing bores within specifications, Chamber size, rocker arm ratio, True TDC, degreeing the cam, Center the bell housing on the block, and a lot of other dimensions that all add up to big gains.
Big blocks, in stock form are stronger, and breath better giving them a performance edge, but they require different and rarer pieces to fit in an "A" body. I too have a 68 Formula S 383 Auto Trans car and love it!
