I'm just trying giving the OP a counter to AJ, I do believe AJ gives valuable info, but seems super focus on VP which I do believe is important but I find something missing from it, most have put a cam in a low cr engine with factory stall and highway gears at some point and probably found it overall better, 318willrun has basically centered his builds/channel around doing that.
Here's a dyno of a low cr 360 and xe250h and xe268h both pick up low rpm tq over stock and there's ton more examples out there.
I just feel something is being left out of his equation.
Pointing out the possible down sides is fine but saying it basically can't work when there's obvious examples of it working is too much.
He constant focus on the issue is to max out the available octane available to return the mist power for a given cam and compression combo. This can be a problem since he swears by the self claimed fact of being able to run 87 octane on 11-1+ engines and small cams.
This may it be a good combo for the available octane in the region as well as elevation. Also a side note of, the pump says 87-89-91-93…. What it will test out to is another issue. This is why I pull his chain among other things.
I’ve stated this before and did receive some pushback though the key is where the pushback is in a certain build of an engine. The constant use of a calculator IMO leads people blindly down a path that veers off the road their use to traveling and others a stray.
Your above video as an example is perfect and a prime example. To push it a step further, let’s pretend the combo with the smaller cam is specked out as a perfect build. AJ loves to come back and state such things as, “Your really loosing out on power with the bigger cam plus your making enough power to completely blow the tires off and waste time spinning them going nowhere fast.
This is only true when you’re at wide open throttle which is an assumption on his behalf that you have no right foot control and did nothing for tires or suspension. The engine side of it is very small potatoes and the increase in compression is very small to make up what the calculators will show as a loss. A loss you’ll never feel and be hard pressed to see at the drag strip. Also when you do, you’ll probably want to chop off your hand for following a fools advice by tearing down your engine to fix a problem which really doesn’t exist.
Technically- yea, he’s right. Will you ever feel 10ft lbs in a 360 producing 400 ft lbs? If you do, register your *** with the earthquake people for their early warning system substitute in case the machine should loose power, your *** will be a OUTSTANDING substitute. But according to AJ, you’re an idiot for a few things and it starts with assembling a bad combo.
