    My dad was telling me about his first car, a 1964 EH which he got for $700 cash when he turned 17 in 1979.

    and he was telling me he modified it, stroking it to 192 from 186, celica gearbox, webber 4 barrel carby and had it blueprinted and balanced...

    so my question is that what exactly is blueprinting? what is involved with it? what benefits does it give you? and how much does it cost?

    just a curious 16 y.o. in search of answers:hit:

    cheers guys

    Blueprinting is basically making the engine match the specs of the engine. Due to coreshift & relaxed tolerances it is very rare for an engine to be exactly right. It usually involves machining the cam, crank & decks to be perfectly aligned with each other. Also the pots are machined at the correct angle to the crankshaft centreline.
    This allows a slight performance game as the engine will run slightly better as each cylinder is optimized. This is only a basic explanation & there is a bit more involved.
