I'm finally about to start assembling my 2366. Right now, I'm most nervous about wiping out a lobe on my new cam, a SCAT C35 (.495 lift, 285 duration) - I am using matching SCAT lifters.
Really just wanting to get my plan on paper and front of this audience to make sure I'm on the right track and to put my mind at ease. Here's what I'm thinking: 1) Use graphite spray on cam and lifters 2) Liberal application of the supplied assembly lube (the thick stuff) to the cam and lifters 3) Since the lifters have a lube hole in the center of them, prime them with assembly lube 4) Fill pushrods with oil 5) Use Brad Penn break in oil 6) Don't install rocker arms until after oil pressure is built so I don't wipe off the assembly lube during the pressure building process (IMG:style_emoticons/default/confused24.gif) |

My .02
1) Overkill, the cam assembly/breakin grease and breakin oil are fine. 2) Yes make sure is well coated. I also wiped some on the face of the lifter as well as the ends of the pushrods/rockers, etc. 3) Overkill and good luck trying, those are needle thin holes 4) a squirt or two with oil can should be fine 5) Yes, this is a must. 6) Yes. I did this but remember this will only fill the lower journals and bearings. Lifter bores and pushrods/upper valvetrain will not pressurize and oil pressure will not build until you have it all installed. Most importance is guaranteeing the engine will start (good spark, proper orientation of rotor, plug wires, static timing and fuel supply) a proper breaking of the cam, generally keep throttle at 2500-3000 RPM for 20-30 minutes depending on the cam manufacturer. I understand your stress, did this myself just a few weeks ago.... QUOTE(VWTortuga336 @ Dec 4 2015, 10:07 PM)  I'm finally about to start assembling my 2366.
