You don't need it until late anyway August Chris

True and not true. The plan is to have this thing up and flying in 2016, but knowing how long it took to get a custom crank made - which this will require - I'd like to see it before my summer gets hectic with work.
Mark's already running three simulations in preparation, but I'm physically going to have to disassemble it and do some measurements to determine precisely which way to go.
Questions we'll be looking to answer - this time, BEFORE I start cutting things -
How much, if any, can I shave off of the block?
What is the volume of the combustion chambers?
How thick is the head, and how much might I be able to trim off of it?
It is aluminum - might I be able to do some welding to configure the combustion chamber to better promote flow/swirl/quench?
How small can I make the bores before I run into valve interference with the cylinder walls? The engine uses liners, so a custom diameter is a real possibility.
If I go with a smaller diameter bore, and the valve spacing hangs out too far, what are my options as far as either
a - smaller valves?
b - notching the bores?
c - any other options that physically looking at it might afford?
How long of a connecting rod will I be able to/be forced to use?
Are there over-the-counter options as far as HP rods, pistons, bearings, etc. that I can incorporate to minimize cash outlay?
So while I need to focus on getting the Grenade back together, I'd like to know before I go in August whether I'll be able to make this work. It's a long-term strategy, designed to take me into my retirement years . . .
At which point, I might have enough time to start getting serious about this Bonneville thing.
