Mechanical end of K/S tests

[Len Sabatine]

    Most engines produce better power numbers after a "fine" coating of carbon
    is deposited on chambers and exhaust ports. Kinda natural thermal barrier
    coating.  Real TBCs are much better tho
    Mixing in some oil which produces rapid Accum of crust on piston lid
    and chamber walls really does the dirty deed to promote dreaded hot spots.
    Since AL heads sink more heat than FE Heads , the Thermo and 190d coolant
    temp should help the thermal loss dept.

>Finished the SBC with the AL heads that I had smoothed the chambers, and
>exhuast ports.     Other then not being able to warm up, or pass the ESC
>test things are wonderful.
>Probably will have to go to a recirculating thermostat to get things hot
>enough for the heater to be meaningful.
>Also, codes for the ESC, with even an additional 4d timing.
>Kinda a game call, but the engine seems perkier, to drive
>Seems like a well spent $15, in my book.
