Is the 3.4 and 3.6 based of the 3.2?

Thanks for the reply.

My mistake, some post here implys that the blocks were all the same.

I read a couple extensive and contradictory descriptions of sequence of events that result in catastrophic failure the 2.5. The net result though seemed to end up with a chunk out of your cylinder wall flopping around.

I wasn’t aware that the 2.7 suffered the same fate as so many 2.5’s. Just plain was not aware of 3.4 problems at all.

You seem to be implying then that a 3.6. is the only worthwhile upgrade. (not much more point or bang for the buck with a 2.7 or 3.2 swap)
