Well . . found a possible 800 donor engine but, I would use my 620 cases to keep engine # and not have to re-register a new engine . . . Also going for ECU  . . .

would have an 800 mild hc engine under the cloack of 620 cases . . .  [evil]

I don't know what register means in this context, but I advise you to make sure your insurance company knows what you've done, or you're likely to invalidate your policy.

while I wait for engine tool to remobe engine and have mobility . . . I will study "how to" tune the ECU with different softwares and "butt-dyno" . . .

Into that subject, any if the techs in this thread could recommend a "good NOT expensivo" dyno with pros and cons . . . it would be a great help, maybe I could become "that guy" and get more business by attracting other shops and maybe purchase a tunning software or 2

Swapping the 800 in place of the 620 was the single best hp gain I got. I spent less than $1/cc for it. Took a day to swap in. And I've put almost 80k on it since.
M620 turned M800 but then back to M620 after the M800 died at 110k, and now to Multi 1000.

What compression ratio would I attain if I used the FBF 12:1 750 pistons with 800 cylinders and  620 heads ? The reason I ask is FBF are currently out of 88mm 11:1 pistons that would give me 12:1 in a 620.

I'm not capable of giving you that number, but it will likely be high enough that you'd need race gas.

If this is a track only bike that's fine, but are you going to carry 5 gallon pails of fuel?

As it is, 12:1 might be tough with pump gas.
