Ok just ordered a digital rpm window switch from msd and a single stage retard box part # 8982....i was initially going to do a 2 stage dynotuned chip but found out it would cost north of $800 so thats out the question for me.....i will be running a 100 or 125 shot on a 347 stroker with 10.5:1 compression afr185 heads and a cam ground just for the juice...all forged internals.....with a hundred shot is 8 degrees timing good enough or shoudl i go lower i got the colder plugs already...and the rpm switch is it ok on @ 2500 and off @ 6000 rpm good??
