We're using the 181 crank with the two piece seal. The machine shop will regrind the rod journals to 1.980", offset to the outside radius. That's a 2" journal minus .020". That moves the journal centerline out and create a 3.655 stroke, (approximately). With a bore of 3.905", (+.030") that works out to 175.10 cid.
I'm planning on using a forged flat top piston and a 6" Scat H-beam rod. Ross has the piston I'm looking at. It's designed for turbo or nitrous and with zero deck height will produce a compression ratio of right at 9.5:1. I understand from tlowe that he has most of what I plan to use and I've been in contact with him.
DO let me know how your build works out. It'll be late fall before I finish the rebuild on mine. I'm having too much fun driving it with the stock setup to pull it down now. I appreciate all of your input and any info you are willing to share.
