Default Which Spark Plugs

I havn't seen much discussion on proper spark plugs to use. I'm at a loss and I would appreciate some help. Car is blown bbc on gas. Ignition is a msd 6al. I also wonder if there is enough ignition for this engine.

Depends,

How much boost are you running?

I recommend NGK racing plugs.

A 6AL would probably surfice for the street with minimal boost but if your racing and stuffing it pretty hard, I'd go on up to the 7 series.

It depend on the engine build whether you need long reach or short reach. I found Autolite plugs to be the best design.
