Out with the 340 & in with the 410 stroker!

Update,
cylinder pressures are between 165-170psi so far.
I found disturbing plug readings and found there to be too much total timing[37*] now 32*/24*intial. I'm gonna raise the initial and make a bushing limiting advance to 4*=28*initial/32*total. we'll see what it ends up being when I do some testing though.

Right now in 1st it'll rev 6500 and then shut off, keep in mind it has an LD340/750 on it.
