is this a cause of detination 421 serval cold seize

With a flat plate 22cc volume dome at sea level should put you about 13.1:1 if i done my math correctly so that would be a little bit much for pump fuel. At elevation that should be about right with little to no added timing. Taking Jon down to a flat plate volume of 24cc which should put him at 12.1:1.

 

 

Thanks Andy,you the man,ill let you know what the squish and comp is when i get the engine back together

if the dome profile was changed it wouldnt have as much issues with pump gas. and yea pump dosent like timing! if your going to "play " with pump you need a better suited profile to run higher comp.

 

dynas are a digital ignition and HATE outside "noise" like coils charging and firing, and stators winding up and plugs firing and making all kinds of RF bla bla bla. they dont like to be next to the coil OR fire non resistor plugs. i have had one just take a shit after about 6 years.. i thought you could download the flash to the dyna and compare it to other maps? or maybe i am thinking of the injection. been a while since i played with the maps on one.

 

the cool thing about a dyna is it only adds timing where you want it even the stock curves go back to stock timing on upper rpm's where you DONT want timing on a plate timing curve advance you do advance the entire curve.
