Automotive News & Views Buying American Cars What Does It Mean?

With parts coming from everywhere, does "Buying American" have much meaning anymore? Is quality and price the bottom line?

You bring up a very good point, Andre. A lot of people focus on internal displacement, and talk about specific output (HP/liter). But what really matters is the overall size and weight of the powertrain, not the interior displacement. Here's a photo comparing two Ford engines. The pushrod is a lot more compact. -juice

Replying to: andre1969 (Mar 13, 2006 4:13 pm) A pushrod has smaller heads than an OHC engine of the same displacement, but a pushrod of the same *power* will be as large as the OHC engine since it needs a significant displacement advantage to keep up. |

it looks like the Toyota 3.0 V-6, when it had an iron block, was around 469 pounds. When it went to aluminum it was around 401. Now I'm guessing this is the same block that is still around in the Camry and Avalon, as the 3.0, 3.3, and 3.5. So unless something radical has been done to it, it's still probably in the 400 lb range. So even though many of these more modern aluminum engines OHC have their advantages, weight isn't necessarily one of them. Juice, I always thought the Ford 302 was a tiny looking thing anyway, but seeing it compared to the 4.6 is truly astounding! I've heard that the old 460 big-block actually takes up less physical space than the 4.6! At least the DOHC 4.6. It might still be a bit bigger than the SOHC 4.6.

the 5.4 won't even fit under the hood of the Crown Vic. I remember a few years back, before the Marauder came out, some enthusiast rag tried to make their own Panther musclecar by taking a 5.4 and stuffing it in the engine bay. There was no hood clearance though, so they had to cut it and put on a scoop, bulge, or something so it would close. I never understood the term "Modular" in reference to the Ford 4.6/5.4. Is it really any different from, say, the Chevy smallblock and the myriad of displacements it came in? It ranged from a 265 all the way up to a 400, all with the same basic block.

| the "modular" V-8 really isn't any different in concept from, say, the old Mopar smallblock, which was available in V-8 sizes of 273/318/340/360, and later the 3.9 (~238?) V-6, and the 8.0 (488?) V-10? I guess the only difference is that with these being pushrod engines, they were always just 2-valve heads. | |
