Whats the best way to Pre-Lube a FE motor? Also, what is the best way to adjust valves whrn you run a flat-tappet cam? And finally how should I do the break-in after I run It for 30 minutes to break in the cam? I am really nervous that I will break-in the cam wrong and have it go flat again. Last time it went flat after I put in new lifters when I had a valve job done.

I've never had an FE, but don't know why it would be any different than a small block when it comes to breaking it in. I run the cam in by running the engine at about 2500 RPMs for about 1/2 hour. After that, I dial the engine in, and then drive it like I stole it. The only real thing to watch for in breaking in a new engine is not staying at any constant speed for long periods of time. Vary the engine speeds a lot during the first 2000 miles to seat the rings.

Oh, and change the oil after the first 1000 miles to get all the engine assembly lube out of it.

You pre-lube it like anything else. I use a broken distributor with no geat & a 1/2 hp reversable drill. Adjust the valves with a feeler guage to the specs the cam card gives. If you don't have it, start at .025. Breaking in a flat tappet depends on hydraulic or solid(as does the adjustment). Hydraulic cams break in the same as a solid but most solids run a high spring pressure that requires 1 hour on outer springs only. My main thing to do is break in the cam, I use solid cams mostly, tune it a little, & go drag racing! I never have engine failures or sealing problems. If the engine is new almost all reangs "seat" immediately, if it's slightly used, they already are. If your FE is a hydraulic I'll assume it's non-adjustable, if it is adjustable, run the oil pressure up then tighten the adjuster down while turning the push rod, take out all the slop but the push rod must turn! Good luck...
