360 Rotating assembly
Does that sound reasonable
IDK,but I can tell you this;
I run my aluminum-headed combo at a minimum coolant temp of 205*F by the IR gun.
at low rpm/low mph the engine has one very nice personality. As the rpm rises it seems to make more power progressively than it should. By the time she goes thru the Eighth mile traps, she is charging way harder than I anticipated. IOW the power is not linear, as you see on typical dyno graphs.
My theory for this phenomenon has always been that at low rpm those aluminum head chambers are running "cold", but that as the rpm rises the heads have less time to get rid of the heat, so the chambers run progressively warmer, and the engine responds accordingly.That's been my theory.
This theory is partly supported by another phenomenon; When I leave the house, it is only 2 minutes to the hiway. When I get there I boot it up normally (being nice to the engine), and leveling off at 60mph. Then over the course of about the next three miles, the engine will gain 3 to 4 mph, with no throttle change. She has no choke, and my idle circuit is slightly rich. The terrain is about dead-flat. In another direction, the Hiway elevation goes uphill, and the phenomenon persists. The rpm is 2240 by the math. My theory is that as the chambers come up to temp, the engine makes more power, even at 2240 rpm.
The combo is as stated in post 16 and in the sig.
Car has gone 93 in the Eighth at 3467 pounds at 950ft, with an HE3038 Hughes FTH, which is 230/237/110+4
The Wallace calculator makes this out to be nearly 440 hp IIRC. The engine is exactly 368 cubes.
Now my question has always been, how does such a tame combo go so fast?
BTW, I was shifting like I always do at 7000 rpm, which Rumble will explain, is insanely high for that cam. No nevermind it went what it went. The trap rpm for that mph is 6140; but the tach was reading 7000... nearly right from the starter box. My clutch was not slipping, and one of the track officials came over on the return road and said the tires were still hazing thru the traps. Ok I get it's a crappy track, but 93 is still 93.
