What year is that 302? I ask because the 351W in my 77 LTD II was rated at 290@1600rpm. It was decent even in a 4000lb car with a 2.50 rear end. Thing had a crazy top speed to with those gears, never had the guts to string it flat out in 3rd (FMX trans) but it would peg the speedo (and then some) in 2nd.

'87

Belt system looked like Crown Vic.

It was out of the car and the sellers attempts to describe what it was out of only made it clear he didn't know what it was out of.

I think BDAB's talking about Hyundai's HCCI project. There's a bit more about it here:

More recently, Mazda has been making headway with their Skyactiv-X project that combines spark and compression ignition at different times.

I think it has to be Hyundai because the article was talking about it as a replacement for the 3.8l in the Genesis and a possible engine for the Kia Stinger

That stuff is pretty cool, i fugured hyundai would realize what they realized though.

As far as the mazda goes, if im undedstanding right, it can run in compression, or a hybrid mode. But if it were to run in compression mode for a long time, wouldnt the engine still suffer the ill effects of detonation unless it was built heavier to compensate?

Not sure, I had the same curiosity. I assume that they do need to build the rotating assembly a little stronger than the average block. At lower power levels you'd need it to handle the detonation (just like a diesel), and at higher levels when the supercharger is rolling hard to handle high cylinder pressure. Presumably we'll see this thing on the street in another 18 months (after lots of testing) and real world results will follow.

Hopefully they test the crap out of it. Its a pretty neat idea, but hopefully it doesnt end up like the various early 80s GM calamaties, like the 4-6-8 cadillacs or the 350 diesels, which were cool ideas at first but piss poor planning ruined them in the public eye.
