Re: engine break-in (ridged84)
My engines get about 10 minutes to warm it up to operating temperature...check to make sure nothing is leaking or making bad noises, then it's out to the road to open it up and see what it will do!
However, your building may have the engine under warrantee, so check to see if the warrantee requires a break-in period. Then, read between the lines and it will say, "take it easy on the engine for the first 3 months, then by the time you start to actually "use" the engine then the 90 day warrantee would have expired!"
Also, ask Bence about how he was going to take it easy for the first 1,000 miles, then about 100 miles after getting it on the road he's talking about the awesome power of his new 454...lol. It's very difficult to hold back when there's finally some power under the hood.

Re: engine break-in (ridged84)
Before you start the engine make sure you prime it. You can do this by pulling the distributor and getting a long shank with a screw driver type slot end on it and putting it down the distributor hole and turning the oil pump with a drill until you get oil pressure. After the car starts you should rev the motor up to about 2000 rpm's for about 20 minutes or so to get the cam broke in. Your builder should tell you what he recommends. I'm sure everybody has there own way. Good luck!

Don't use synthetic oil to break in your motor. Synthetic oil does not let the piston rings wear to seal a new motor. You can switch to synthetic after 3,000 miles.

Rockn-Roll:
It was actually about 35 miles :D. I made sure there weren't any leaks and then I took Gordon's advice and went out and dropped the hammer (6500RPMs). I've come to the conclusion that you have to run them like you're going to run them. I still make sure the engine sees a 6500 blast every now and again. As long as you have moly rings and have properly broken in your cam you should have nothing to worry about so long as the engine has been properly assembled.
