Tim:
Looking at what you have left to do, it's a little of everything. If this were in my garage:
* hook up fuel line to fuel pump.
* re-install shifter to mid-shift point; pour in transmission fluid (have a bucket under it for the level hole)
* Get more info on the rod-length of the hydraulic clutch assembly from Forte's. There is some info on the FFCars.com forum where Mike hangs out regularly and some builds using the Quicktime bell housing with it I believe. Otherwise, I think it will be pretty straight forward - cut down some rod and test.
* Install carburator but do not install the linkage assembly until you resolve the driver side header issue.
* Interior work: carpeting, Kirky seat build up.
* Check rear-end for fluid; add if needed (but I'm guessing they did this at ERA but never hurts to check it again.)
* Contact your engine builder and determine if they re-torqued your heads and intake after initial run-in / dyno; ask if you should do it again after say a few hundred miles.
* You could actually hook up the radiator hoses top and bottom as I don't see any issues with that. May even want to start adding
antifreeze to it, however, since you don't have your alternator bracket yet, I'm not sure if you can mount your overflow tank or not since I'm not sure where it mounts to on the engine.
