Why drive a truck with a big six cylinder?

[ArdWrknTrk]

I guess I should have said "in its stock configuration".

With 7 main bearings the 300 has a significant enough foundation to support a lot of power - and RPM. However, with the log intake and exhaust manifolds, not to mention that they are on the same side of the engine, it is difficult to get them to rev very high.

Enter the Frenchtown Flyer with his cross-flow head and tubular intakes and exhausts. THEN the 300 can rev.

He says in the comments that the head is not really optimized.That it was a Ford test piece for fuel efficiency.And, that he upshifts at 6.9-7k!

Yep, and that head is one of a kind. Just think of what the 300 could have been.

The really nice thing about a I-6 is the almost perfect primary and secondary balance.

They are so smooooth.

I had a girlfriend shortly after HS that had a Hartge tuned 3 series Bimmer.

Cindy's car seemed like a rocket ship.

Our son really likes Beemers, and had a 3 Series for a while. And even though it was stock I was impressed with what that I6 could do, and do it so quietly and smoothly. I can imagine what the tuned ones, or even the M3, would be like.

Hartge is to BMW like Ruf is to Porsche or Brabus to Mercedes-Benz.

That car was Henna red, had a polished stainless header, cam, intake, BBS/Bilstein/Pirelli's all around, splitter & spoiler, and of course the signature oval exhaust tip.

Too much car for me to push its limits.

WAY too much for a 20 yo girl with no survival instinct.

The only I-6 I ever had was a Dodge powerwagon dump truck.

Anyway.... sixes are cool!

I took a ride 2 weeks ago in my boss's 2018 Dodge Ram with a 6.7 Liter straight six cummins. We got in and he fired it up.....I said "this is a deisel!?" It was sooooo quiet!! I just couldnt believe it. So I rolled down the window and sure enough, you could hear it

I asked him to "get on it". Man....that huge crew cab dodge went like a rocket ship!

I looked up the specs. I think it was something like 360 hp and 800+ lb ft!!!

... and it's a chip away from another 20-25% horsepower.

Think about that.

80-90 horses in a few minutes without ever turning a wrench (or even opening the hood)

Jim, modern tech is cool. Its just so expensive. I cannot imagine spending $45,000-$80,000 on a truck. I guess I am in the wrong business if there are plenty of folks who think thats ok to spend that much on a vehicle.

I read that Chevy is coming out next year with a pickup that will break $100k with options.

I'm glad my 250 was $22,500.

On in-line sixes, a few items. First in the early days of NASCAR, one of the dominant cars was the Hudson Hornet, it had a massive in-line six, 308 ci, granted a flathead with the same side intake and exhaust. It had the optional Twin-H setup, and the smart trick was a Denver head (higher compression to make up for the high altitude), gobs of torque and on the mainly short, frequently dirt tracks the combination of that engine and the "step down" design of the Hudson made it a power to be reckoned with, classic duel was Lee Petty in an Olds against Herb Thomas in a Hudson.

The Brits love sixes, Austin-Heally 3000, Jaguar XK engine, Aston-Martin DBs, even Rolls-Royce and Bentley ran in-line sixes for years. The Austin-Heally 3000 was originally a lorry (truck) engine, just like the Triumph TR 2,3 and 4 were originally tractor engines (Ferguson). The Jag and Astons are DOHC engines, but the jag has a very long stroke. There was a team from Northern Ohio that built a jag 4.2L that reved into the 7 - 8 K range with help from Jack Clifford, horsepower was unreal and the damn thing howled! It was built to beat the Datsun Z cars when they were dominant in SCCA racing. An interesting note, bore spacing and head bolts are close enough to the Ford small sixes that the Jag head can be adapted.

Look at what the Australians did with the Barra engine, it is derived from the lowly 144, 170, 200 family.
