Uncle WD can be grumpy old man sometimes.. j/k!
But that sounds about right to me. As you can see in my sig, the pistons don't like detonation. I was running 12-15 psi on a 180k block with 370cc injectors. That was before I knew what the beans detonation was. Ran awesome with the 740cc's I bought, but blow-by was a b***h because of the broken ring lands. And I was still able to just hone the block after all that! Try that with an aluminum block. Or maybe they're sleeved? I have no idea. It's almost 5am and I wanted to get my $.02 in. I'll see if I can find it, but I found a video once of some kids that hopped a curb and bashed a hole in the KA's oil pan. Then the commenced upon trying to blow it up. The video is about 7 minutes long, cutting in and out, of them beating the beans outta it. They finally threw a rod through the block and actually went back and found it. Funny thing is after they tossed the rod, the kid dumped the clutch and it fired back up and he kept on beating on it. I know I'm totally off topic, but I'm trying to get a comparison here. The KA is a very stout motor. Most people say it's a truck motor, but I think it's a I4 on 'roids in stock form.
*edit* Found that vid of the horrible abuse this KA went through. These kids should be shot.
