Re: The next drag racer gears up!
Evaluation: porosity within the cylinder head casting, [img]<<GRAEMLIN_URL>>/mad.gif[/img]
The small dark spec's are deemed to be casting imperfections that have channeled their way to the center / forward bolt hole.
The best remedy is still in R&D, which is a billet head. So, while the engine is at the builder we will upgrade it to 'version 2' with a bore/piston/rod change. While I might need to add a little more weight to slow it down, the bigger bore pulls a better carb signal and allows for better tuning and consistency. Till then, we will start dialing in the backup engine - hopefully tonight.
