Let's see if we can shed more light on your comments.

Transfer height (linear measurement) determines timing on a 360 degree wheel. 164 degrees of total timing for the exhaust port determines a height on the exhaust port. If is ROAR legal or not is an issue that should not bother anything. When your engine is teched, the exhaust transfer height is measured on milimeters, not timing degrees and if is higher than 4.5mm, you're deemed illegal and you're out of race.

Reducing on 7mm the conrod lenght is a no no. Shortening the conrod makes to collide the piston skirt with the counterweight of the crankshaft and you need to remove more material from the piston (still, doubt if current pistons can accept to radical material remove) this piston will be weakened up to a point that will be unstable into the sleeve and will rock into the sleeve, scratching it and making it ovalized.

Marine mentality is fine for boats that only rely on high rpms to produce power not for cars that run on a closed track (probably are fine for tether cars or planes too), hence here their exagerated exhaust timings along to ultra-high compression ratios (or ultra small combustion chamber heights - name it as you prefeer) that rely on the extreme timing to control what occurs into the combustion chamber. As a plus, those engines run with a water cooling system, so their temperature never reaches the extreme temperatures you can find in a .12 engine with a closed body.

Edward, probably this is your worst problem, you're directly extrapolating what works on boats to cars, and this doesn't work on all cases. Some of your ideas are interesting, others don't apply, others simply... well.

Here, many people works and make 1:1 engines for a living (Engineers, motor builders, mechanics), others simply are gearheads (like me, have their own experience building their own engines, but their money is earned in other places), other simply rely on the experience of other people because they don't want headaches with engines.

Some of your advices aren't questionable are directly dangerous and harmful to people with light or no knowledge of our engines (0.008" of chamber height is a fine example, another is to make propaganda that for making power, the best is to reduce Nitro on their fuel).

If you're right, all the guys that run on Funny cars or other Top fuel categories are doing a complete nonsense burning a mixture of 90% nitro and 10% of Methanol, running 100% Methanol is much cheaper to run their multi hundred thousands cars burning thousands of dollars on each weekend they run.

On this last assumption, you're extrapolating what happens on FAI categories that are limited by rulebook to low or no Nitro percentage on their fuels to car engines, who can run and are designed from the ground for the use with fuels with Nitro (trying to carb an engine running with no Nitro is a bitch to do...).

Nitro is vital and necessary for the chemical process that happens into the combustion chamber one of their actions is to give Oxygen and Hidrogen during the combustion, other less known is to slow the flame speed of the methanol burning, needed to control the explossion on the combustion chamber and help to give more power making the burning of the fuel and the explossion longer in time hence producing more overall power.
