My 427R was drinking
oil and down on power at @ 30,000 mi. Dennis Olthoff had done the install and does all of the work on 1061. I took it back to him. Diagnosis: broken ring land on number one cylinder. Fix: complete rebuild - custom .015 over pistons, cylinders honed, crank polished and balance checked, deck surfaced, complete head job, intake angle cut to properly match head angle, new rings, bearings, timing chain, pins, seals, etc. About 2000 miles on the rebuild. It burns a little more
oil than I would like, but not excessive by any means. It runs like an absolute scalded dog. Pretty sure it is stronger than the day it was installed brand new. Dennis is in the heart of NASCR country and surrounded by absolutely fanatical engine builders/machine shops. I trust Dennis choice of support people 100%. It definitely did not go back to Roush. Local drag strip will open up in March. I'll be able to do an objective test then to verify what my ass in the seat is telling me.
