Well I intend on building the engine and at least trying the knock light but the J&S seems like something after I get after the engine is pretty and back in and before alky injection. Especially since I'll have forged pistons in there to last me until then.

I know I've been riding the fine line (and obviously crossing it) with timing on these cheap engine setups. So how is it that these tuners and engine builders know where to add and remove timing on these engines without knock sensors before they give it back to a client?
