NOSSSS, we need NOSSSS!!!!!

I’m waiting to see them swap pistons side to side like I did in my old Chrysler.

Im sure not all piston mfgs do this but back in the day of Mopars “Direct Connection” they said the wrist pins were offset in the pistons to side load them so they wouldn’t slap when cold.

They said if you swapped side to side, that cured it.

Crap, I've been doing it wrong. But I have a 2,000hp tool cabinet. LOL

My tv hasn't left the Motor Trend channel since the election last fall. Lots of good information and some pretty good humor on most of the show's over there. Some shows are almost infomercials but still worthwhile. Definitely better on my blood pressure and mental health than the constant 24/7 drone of covid, politics, conspiracies, etc. that occurs on most other tv channels these days.

Just watched one on changing firing order on changing firing order on a 572 Chevy.

At peak it showed +4 ft lbs and +2 hp’s.

Average through full pull was debatable.

Their conclusion was as my old man always told me, and Smokey Yunick also said, that if you change on part in the equation....., you must adapt the tune to it.

Take away for me was them thinking outside the box.
Who’d a thunk it?

Reminds me of a story I read about a team that set the record in land speed racing in the flat head class.
The flat heads horrible air flow is their main limiter of power.

So what did they do?
They reversed it!

As in, intake was now exhaust and exhaust was now intake!
Was a huge jump in power and tech rules legal.

You think you know motors pretty good and then you read that 😂

Being a huge Smoky Yunick fan, whose favorite thing was screwing with the heads of tech inspectors :-), his famous quote was, “it’s not with the rules say, it’s what they don’t say.”

He would figure something out, get away with it for one race, the tech inspectors would try to throw him out, then he would challenge them to show him in the rulebook which he knew they couldn’t.

They would change the rules for the next race!
He didn’t care he had won that battle :-)

In the early days of stock car racing where they were street-based cars they had a tech rule that said the camshaft had to be OEM lift and duration.

Smoky figured out that they did not specify timing events in relation to crankshaft position.

So he made his own camshaft altering the lobe centers which gave him substantial power, and won the race.

Tech inspectors protested, tore down the motor, and Smoky was the only team that they allowed to tear down his own motors while they observed.

A camshaft is very brittle and as he was handing the camshaft to the tech inspectors he pretended to trip and dropped the camshaft which broke into 16 individual lobes rolling in different directions!

He smiled at them and walked away!

I thought the one where they use solid rollers with tight lash on a hydraulic cam was very interesting. For me that's the way to go for future builds. They measured 58 grams difference and that didn't include oil in the hydraulics. Bushed solid lifters are certainly more durable and provide better valve train stability. The power gains are worth it alone.

May be apples to oranges, but still food for thought..

My engine builder back in the ATV racing days did a lot of flow bench and dyno testing, On a 250cc 2stroke motor, the clamp on pod/sock air cleaners clamped to the mouth of the carb vs a 6" tube/"velocity stack"

We were able to go down a couple jet sizes with the 6" tube running same egts and cleaner response. without the tube, air was still turbulent/tumbling as it went past the jets ,With the tube the airflow was better aligned and had stronger pull on fuel thru the jets and better atomization.

Yup, and Also, one carb per cylinder , that air cleaner tube became part of your intake runner.

I totally agree with this. Lifter needles going through an engine seems like the most common failure mode. Why not just eliminate it?
