My question is... is this a constant with all LS1's for example? Let's say you increase stroke and then increase cam duration, and even have some cam advance ground in... shouldnt the injector timing be altered to better match the earlier opening of the intake valve?
I am going to try and play with this... but I dont know what to watch or log to see the effects.... maybe AFR? Richer means a more complete burn?
I am open to suggestions.
