(and does anyone know where a Teksid block is LOL)
Mmm, my friend had to use some thick ass head gaskets come to think of it or else he'd of been north of the legal compression limit. But with some 26X/27X degree cams he ended up with a 300whp/3XXwtq freak that ran 13.18 at 5000'. Aaron kind of reminded me of that, as we never really knew exactly why his car kicked the snot out of all the other 4.6s we knew of. He was within a couple tenths of a centrifugal supercharged Edge. Those Teksid blocks aren't that hard to find at the local pull and pay. It's all about timing, and they don't magically disappear the way LS engines do. I think they're about $220 out the door for a complete engine. Now there's this:
Ford cars 1999-2004 using cast iron blocks subtract 100lbs from weights below
So they acknowledge the aluminum block, but not for 96-98 cars and I do believe those Cobras, which are allowed to run in CMC, had the aluminum block. So the way I see it, 96-98 can run aluminum block and no weight penalty.
