Here's what Don Dulmage had to say way back when about cam break in. (Not necessarily for Rich, who knows what he's doing.)
Re breakin. Here is what we do and we have had good success although it is harder than it used to be according to al accounts from experienced builders.
I use the supplied cam lube drirectly on the lobes . i also smear the whole cam liberally with wheel bearing grease and dip each lifter in the greease on its bottom before installing it. I do not use multigrade oils but use Dg diesel truck oils 40 wt or 50 if it is really hot weather (90f+) I prelube the engie (using my intervenus prelube invention but a drill running the oil pump is fine also.
I make sure the engine will fire immediatley . timing set in the will run for sure zone and i fill the carb float bowls manualy. When the ngine fires I DO NOT EVER let it idle for at least 20 minutes but keep it around 2000 to 2500 jabbing the throttle occasionally . if I need to adjust or fix something I shut it off and restart with throttle applied . When the 20 minutes is reached I shut it off and change the oil and filter while it is still smokin hot. This removes my assembly lubes while they are still suspended in the oil at temp. I refill with my same good oil and drive it like i stole it .
The number one best way to make sure you lose a cam BTW is to crank the engine over on the starter till you have oil pressure. By the time you have pressure you already dont have a cam. Avoid cranking and idling like it was the plague. So far this has worked for me well and i am in 35 plus years but i still worry as much as ever and even more since lifter manufacture became a martial art form and moved to aisa.

Regarding "Drive it like you stole it...", I think he meant step on it, but I've always avoided incarceration by keeping my stolen vehicles under the speed limit. Just sayin' ...

You are right but this is not a new engine. Only the heads and cam are changed. The cam will break in before the parade so all is well there. It's the same short block that has been in the car since '06. It doesn't have many miles on it though. I just cleaned it up and checked it out.But yes a parade would be a disaster for a fresh engine. The time of year, hot, and the conditions, extremely slow, really test your cooling system! My potential problem is that the tune will be off for the new combo. I don't want to run lean and fry it.Rich Kinsley '64 Dodge Polara 4dr 318poly w/goodies======================================================================================================================================On Tue, Aug 16, 2011 at 8:50 PM, Jay <shelby_nut@xxxxxxxxx> wrote:
2. Drive the car easy for the first 10 miles or so, varying the rpm's from 2,000 - 5,000.
3. Then, start bringing the engine up to maximum rpm's and letting the engine bring the revs back down by coasting in gear (vaccum pulls).
4. Repeat several times in order to create maximum heat in the cylinders.
5. Drive around at lower RPM's for several more miles, remembering to vary the speed of the engine every couple of miles.
6. Repeat number 3, 4 and 5.
7. Park car and let the engine cool down overnight.
8. Repeat all the above 2 more times.(This is just a break-in procedure I found on the net from a 35 year engine builder, they all seem to have there own variation but the concept is similar, varying speeds, varying loads)Jay

Today with the help of Dodger and Terry Bohnart I got the short block in place on LeRoar. Everything is going fine. Next Sat, Aug 20th is the Bellevue parade. I am trying to get it ready for the parade. The heads are due to arrive on Thursday. I will install them in the car. I won't have much if any time to tune so I hope it is close enough. A parade is the most severe test you can have for your cooling system. I'll keep my fingers crossed.Also Dodger told me our 1/8th mile track is gone forever. The flood wiped it out and the health dept won't let them rebuild unless they replace the soil as it is supposedly contaminated by sewage from the flood.
