Street 360 W/.528" P.S. Cam

Here is another interesting tight LSA cam story. Written by Mopar Man Steve Dulcich, PHR Dec 2011. Many years after the Kaase engine I mentioned earlier in the thread.
This engine was entered in the EMC contest. 426 ci, LS engine with a single plane intake, 4 bbl t/body & port fuel injection. The cam was a single pattern hyd roller cam, 237 @ 050; 104 LSA.
[1] About extra exh duration, the engine builder said this: "If I would have added 4-5* or more of exh duration it would have hurt the low end"
[2] Builder: "The tight LSA seems to make a lot more midrange tq, which was the focus on this engine. If I default to a tight LSA cam, that will always pick up midrange tq."
[3] Engine made 643 hp @ 6200 & 503 tq @ 2500 with a cam duration of 237 @ 050.
[4] Summary at the end:

I believe Steve D wrote it, but 100% sure.

" The engine was built with one gaol in mind & that was to maxinise it's power output between 2500 & 6500 rpm. That means the tq comes in like a sucker punch right off the bottom end -where you least expect it- & keeps coming at you as the needle on the tach swings to the sky. Right off the bottom at just 2500 rpm, this combination assaults the senses, with over 500 ft/lbs on tap. From that start, the tq tq piles up in abundance, pouring on the twist until a peak of 600 ft/lbs is reached at 4800 rpm. That is over 1.4 lbs ft per cube of shove, & it is on pump gas."
