Im kinda surprised that no one has really mentioned the driveability aspect and how LSA effects it--not even me and its in the thread title--LOL. B3Re has touched on it a bit--Tight LSA's lend themselves well to power delivery that hits like a sledgehammer and while impressive is not always satisfying or the fastest way from A - B (traction). Tight LSA's are total crap at part throttle or just off idle. Tight LSA's are a nightmare with stock converters and highway geared rear ends. Tight LSA's on the street require a hot plug in order to burn off all the crap the builds up on them too but you can run into pre-ignition and detonation due to the higher than normal cylinder pressure @ and below peak torque. Look I build a few circle track deals and tight LSA's are employed here and its almost the tighter the better too. They have their place just not in my street car. J.Rob
