800 Mile Roadtrip

[icanfixall]

Well I ran mt new motor ******* an 800 mile trip to and from Scotsdale Arizona...... No problems. I saw 1050 degrees on the pyro, boost was 11 lbs. The coolant reached 228 degrees while the trans was at 170 degrees. The motor oil temp peaked out at 260 degrees while all this was happening pulling a steep grade. I had my 3 horse gooseneck with 2 horses and about 700 lbs of feed on board. After the grade things seemed to run better. Kinda like I found more horse power somewhere. Maybe I burned off the possible ring & cylinder fuel and oil varnish. The motor has 4000 miles on it now but only about 1000 miles on the new head studs. I was happy with what the motor could do. Now as Towcat has said. I'll be happier when I "find something to do" to make it just a little bit better.

Those are great numbers Gary. Have you got any to compare with prior to the exhaust installation? I'm glad to hear the trip went well. Hopefully Mr. Murphy has moved on for good

That's a nice little shakedown run with enough load to rattle anything loose that's going to come loose. Sounds like things are looking up for a change
Any retorques required with the studs, or just smooth sailing from here?

No retorque required but I have thought about it. I used Felpro head gaskets that don't require a retorque. I did torque and retorque the studs 7 times. The ARP instructions state to do this 5 times so the friction between the nut, washer and head is broken down. So I felt a littlw more wouldn't hurt anything but me. I torqued the studs down to 100 lbs and when I loosened them up and retorqued them you could see them walk around about another 1/2 turn before they were tight again. Plus this stretches them like they have been installed. It does something to the metal structure alignement.

That makes perfect sense. As much as the things are really intended to be put on engines that come apart every week, if not, a few times a day in the pits to swap heads or what have you for the folks who are drag racing,it makes sense to work them in a bit more. That's the one thing that has had me worried about studs is the large number of people who have had problems with minor coolant seepages when running studs.

I suppose somewhere in their data is rated the maximum number of torquing cycles before structural fatigue, and all that kind of fun stuff to make your head spin.

Congrat's Gary. Good feeling eh?
Now you just have to live with the
"new engine" anxiety. I've got just over
30,000km (18,000 mi) on mine, and so
far so good. My truck is just about to
turn over 200,000km(120,000mi).

good goin!
