I've always adjust my clutch so that it felt good on my foot. Seriously snug it up a bit till it feels right, just don't over snug it. You should have some play, but it will be minor. I wouldn't worry about your coolant, just start it with the radiator cap off, and continue filling it as needed. This will help bleed any air out of your cooling system also. Don't forget to prime the oil pump. Good luck.

yeah, I guess I'm just getting nervous, already primed the motor, and just finished making the wires for the tr upgrade, I used taylor universals and cut them to fit. I heard someone talking about burping the system, and that got me thinking about the coolant.

Make sure you follow the directions for breaking in the cam. They say to run the engine at about 1500-2k for the first 30 minutes, changing the RPM periodically to direct oil splash to differnt areas on the cam. After 30 min, change the oil.

Re: ready to start rebuilt 258 ???

how much coolant did your engine take to fill?

it should take about 2.5 gallons. if you want to try to burp it, try disconnecting one of the heater hoses, or, if the hoses go thru the intake manifold, try to figure out which fitting on the intake manifold is for the CTS (coolant temp controlled vacuum switch) and slowly remove it to see if there is coolant in there.
