It has MSD pro billet with streetfire box. 20* at idle and 34* all in at 3000.
440 with 915 heads mild porting and polished chambers.
Which plugs looked better? There are two different heat ranges there. First set of pics cooler plugs.
I do have a 10* bushing that I could theoretically get 24* initial with a total of 34* or I maybe I could speed up the curve a bit to get some in sooner?
And btw there were no WOT runs in this cruise.
(Was with the wife) :lol:
