It has been a couple of years since I put the larger pistons in the engine. There was a lot wrong with the car when I got it. It at least needed rings, so I thought if I had to pull the engine and take it apart, why not upgrade the P&C too without making it a stroker. I phoned Pat, he did not remember the engine (of course) but said the 92s would be max and bring the engine up to 1835.
So ... I honestly never experienced the engine running in good condition before I redid it. I did not put in adjustable push rods, but that is great advice and will be on my shopping list. I did work quite a bit with the shims when installing the 1.25 - also with elephant feet (911 style).
I found this exhaust and will probably give it a try when it warms up in the garage a bit. No heat and a tad cold on that concrete. It's affordable and might do the trick. The engine "feels" like it is choked off and not giving me all it can. But that could be wishful thinking. :-)
