    Engine has 30 dyno pulls and 4 competition pulls, all somewhere between 8 and 9K rpm.

    What are some of the factors (engine specs) that allow a large displacement engine like that to run those high rpms and not disintegrate?

    Pretty much the best parts money can buy, attention to detail putting them together, and knowing which parts to use. There are bigger engines making a little more power but they don't turn the rpm and these truck pull guys want wheel speed. We intentionally pulled some stroke out of the original plan in order to run more rpm and make better power through the curve. The bottom end is pretty fundamental. Billet crank, billet rods, light pistons and rings, big fat wrist pins, specialty coatings and really accurate machine work. Lot of attention to detail in the assembly. The valve train is critical and there's well over ten grand just in the heads. Expensive dry sump system, good oil control, staying on top of maintenance like spring pressures is really important.

    and some people think dyno pulls are a strain on their engines .........

    I think the reference was toward the fact that he holds that RPM up there for quite a while, where a dyno sweeps up for 4 to 5 seconds and is done. (That is what I was thinking anyway). Like making pulls on an engine that will be running around in circles. The 20 to 30 pulls to really dial it in with fuel, timing, lash, cam timing and so forth is nothing compared to the heat after heat, weekend after weekend they will see in use in the car.

    It is a shame the injection did not work out, but it would have been really fun to have seen what the injection would have made compared to the carbs on gas. Either way, it is a heck of a build.
