i'm diggin all this v8 and old tech talk but there is much wrong in this thread.
`basically cam is too small to ever ever ever make 475 crank. numbers and predictions aside should be a fun little torquey motor for a stock cruiser and will be fine, just wondering what the goal was here?
` you seem to have a good set of heads on there and what i'd think is the right intake for that combo, don't know why the high compression but ok cool more comp can't hurt power esp with alum heads. the big stroke is much more forgiving in terms of large cams so personally i'd put somethign much bigger in there even for a DD ride.
`a carb never tunes itself not even a little bit shame on you for believing this. air bleeds simply affect the 'signal' the carb sees.
` mopars are great, and the 340 is a legendary motor, ever held a stock 340 rod in your hand?
`power lost measured in % is an industry standard has been for a reallly long time
I think the bottom line here is that you're an idiot, looking forward to seeing it not make the power numbers you have dreamed up.
Thanks for playing ...
I concur
another expert.
did you see that i said tune themselves, which is dull down meaning it will work run right on lots of different motors. thanks for playing.
340 is legendary for being a turd boat anchor
power "loss" measured in % ONLY APPLIES TO COMPLETELY STOCK CARS.
drivetrain's eat horsepower PERIOD. it doesn't change depending on how much power you make.
another know it all

Drivetrain losses are not a constant. They change as the RPM and torque transmitted through them varies. They are usually estimated as a % loss, which is only an estimate and not really 'correct'. But it's not flat number either.
This is elementary. Friction loss = coefficient of friction times the normal force. IE- You place a wooden board on a table and push it across the table. This requires a force. If you put a weight on the board and then push it, it's harder to move because the normal force of the board against the table is higher, therefore the static and kinetic frictions are higher.
IE- two gears turning in oil. The faster they turn, the more losses their are from having to churn the oil. This is a quadratic varying load.
In the same example, power transmitted through the gears causes rubbing forces, bearing losses, etc, and these are linear varying loads. Double the torque transmitted and frictional losses (more or less) double.
Net loss through the two gears is complex.
In short, "drivetrain's eat horsepower PERIOD. it doesn't change depending on how much power you make." is incorrect.
