400/450 stroker....Cheap parts, lotta work.
I'm happy with the work performed by Performance Machine. They decked, bored, honed the block and ground the crank for me. The mains didn't move the dial indicator while checking to see if the crank was straight. I used the same rod and piston to check all the throws on the crank and ended up with deck heights...........
#1) .015"--------#2) .015"
#3) .017"--------#4) .016 #3) Probably me with a minor error, old guys can do that. Edit...it is .016. Found that when I checked #3 TDC, 0 degree difference from #1
#5) .016"--------#6) .0155
#7) .016"--------#8) .016
With my crude instruments (some things built by my Dad in the 1960's) I used the positive stop to set the degree wheel to #1 TDC and checked #6 & #8 and got 1/3 & 1/2 degree difference from #1. Well within my margin of measurement error. I can now cut the quench pads to my desired height and send everything off to be balanced.
