Indy 360-2 230cnc oval Port

My block didn’t fail, but it was flexing. I was wanting to step up the power but was afraid it would fail. It was never on a dyno but ran 6.57 @ 104 and change in a 3260# street/strip Dart.

Just because the block didn’t fail doesn’t mean it wasn’t past its capacity. When a block flexes what happens to cylinder bores? They go out of round and ring seal is compromised. Just something to think about.
