I started with a pan many decades ago, then got a shovel ,and now ride a bike with an EVO. How do the newer engines compare with the last 40 years of Harleys engines ?
What's the best Harley big twin engine ?

Thermodyne,, is that rad8cal pre 1971 sportsters one of yours?
As I got older and I think wiser, I went with a large but not easily fatal dose of power, (engine),, blended with streetability and civility, also in the mix rel8ability and upgrades to all systems on the bikes.. especially major brake improvements. Stopping is more important than accelerating

I was wondering if anyone would notice. I taped into the return line and runs through a cooler works a treat

Yes Mate trying to keep head and piston temp down to stop pining . I do have adjustable timing. Trying to run a reliable performance engine. So far so good 😊

I like the TC 96" I have right now. My wife had a Sportster for a couple years with the evo engine and it never gave me any problems. I rode it more than she did. It was a fun bike to ride. She sold it to my daughter in law. My 2010 Electra Glide had the 103" TC, no problems with it. I just do the routine maintenance and don't ride (too) hard so that probably helps.
Back in 2020 my son bought a new Low Rider with the 107" M8. Wow! Lots of power and fun to ride. That's all I can say about the M8's.

I will add to the display of thoughts and conspericies here..
If one is at the mercy of a "shop" as to what is better and what they deem worse, as needing fixed, then we have that to lean on, their opinion.
Not necessarily correct.
Maybe a way to look at this is, if you had to be broken down on the moon, so to speak, which would you rather have to fix?
A mystery of electronic parts, pumps, computers, and numerous features that may have caused the breakdown?
Or a simple machine with points?
That's how I judge which is better.
Do I need someone to help me, and am I at their mercy?
Or can I do whatever is needed, besides the road?
That's the scorecard I use.

The best Big Twin is the one you have now.
EVOs and Twin Cams spring to mind as some of the best. But bulletproof? I'd have to put my money on the Sportster Evo engine as the most reliable and all-round performer. It may be the smaller brother of the Big Twin, but it outperforms it in many regards.
