Oh as much as I love the LS(x), I do love me some straight 6s. Ford 300, Mopar Slant Six, GM Atlas (4200), BMW M88, M20, and M30. The one I really want to play with is the Aussie Ford Barra engine tho. I think one of those would be nice in my '63 F100 Unibody.Straight 6s, nuff said!
Oh man I'm happy you have that opinion also because the gen 1&2 sbc are garbage honestly. Even with the "amazing" 4bolt mains block you can still junk the motor at f***ing 400hp. They don't make power stock. The factory stock components don't hold up too 1000hp at all. Oiling system is junk. Head design is laughable even the best gen1&2 heads you can get don't flow as well as ls heads. It's all just a giant boat anchor.I was a Chevy small-block hater until 1997. Always felt the 350 was an overrated piece of junk that lived way too long in newer trucks past it's original engineering design. Sure it was a decent all-around engine really, but it had a terrible rod angle (even worse if you turn one into a 383) and it liked to beat the hell out of it's main bearings. Terrible fuel mileage. Don't get me started on the old 305. I've had several SBC over the years, and while they were reliable af, they were also craptastic.
Then the C5 Corvette came out with that glorious new 346ci LS1. That sound, that effortless powerband, that low-end tractability, and LS1 Vettes can exceed 30MPG with a light foot. All of a sudden, GM didn't look so archaic anymore. Sure, there's people who say "pushrods are old tech" but most don't know that OHC is an older design than pushrod. Pushrod engines have a packaging and weight advantage, also tend to make more average torque.
It's all old tech now and it's still glorious.
