Not sure what I will have.. machine shop had problems sourcing correct pistons and rods based on the online info I gave him. But he is trying to come up with something and he is pretty sure he can have it figured out.
That said, in regards to using a 1.9L Core, I realized I was listening but not hearing when talking to Bob on the subject.
The 1.9L and the 2.0L have the same thickness walls, thats what I heard.
What it meant was STOCK they have the same thickness walls. So cutting a 1.9L to 2.0L ends up being similar to cutting a 2.0L the extra to get to the STOCK 305 Pistons. In anotherwoards there isn't anymore meat on a 2.0L than a 1.9L BUT you don't have to cut a 2.0L to get to 2.0L you DO have to cut a 1.9L to get to 2.0L specs.. THUS a 2.0L has thicker walls than a 2.0L Built from a 1.9L Core.
Which isn't an issue making a 1.9L to a 2.4L based on Bobs' original article :

BUT going with even more stroke or more bore, and you could run into issues with a 1.9L Core.
But whats done is done, and Ballos and I are still working on a 2.7L built off a 1.9L Core that was bored to 98mm. But unless there is an "Ah Ha" moment and he finds a cheap off the shelf set of components. It maybe a one off.
Going much bigger than 2.5 ( or 2.46 in the case of the 2.4L builds I have been doing ), is proving to be not as straight forward as I had envisioned. That said its not going to stop me in seeing what my machine shop can come up with using a 1.9L Core and a 2.3TD Crank..
BUT What the 1.9L Core becomes will be known sooner than later, once he has the parts that work and the math lets him know the ccs. I will then run it on the Red Baron, and after I get it installed.. I will find how well it can handle the needs of someone that is only going to stress it as far as it can handle on the interstate, not the racetrack.
I know that the stroker 2.5L builds based off the 2.4L Core have so far proven to be a hell of a lot of fun.. but given that I can only bring over 6 motors at a time and they are expensive, that limits what others can do. That said I will have 7 2.3TD Cranks coming in the same batch and they are much easier to ship.
