Well I don't know about another horror story as a lot of mfg's had the same problem with gaskets! That being said, James we had 12,000 plus when they changed the gasket! Dennis is great, he did my install and delivery Christmas eve on Sunday in the rain!LOL

I was thinking it would be worth trailering down there to see him, Dennis is definitely a legend, and takes the time to come to the phone and answer any questions.. obvioously customer service and knowledge are his priorites! Thats how I run my business, short term cost to keep a LONG term customer!

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.

I had quite a bit of other work done as well...tranny rebuild, clutch, front rotors, ball joints, so things are a little jumbled together, but I believe the actual engine rebuild, parts & labor (not including R&R) was just under $5k.
I might be a little off, but that's close.
