On the crank? Or, just laying there?

On the crank: Just tap the rod bolts gently with a rubber mallet. (NO METAL)

Just laying there: Use both hands, and pull apart..... if that doesn't work, tap them on a wooden surface a couple times, and try again.

 

i decided to have the shop assemble it. too many things to worry about

 

i did tap the cap a few times with a small finishing hammer a few times. hope it didnt hurt anything

 

Probably not. Consider what they have to deal with when the engine is running.

Having the shop do it is great for peace of mind. If you don't plan on doing this type of exercise on a regular basis, then "Needing the practice" doesn't come into play.

Just have them shortblock it for you. Should be golden.

 

that certainly does come to mind... i dont know where "handle with care" ever came into play.

i had 4 pistons in, but there were FAR TOO many things worrying me. i took it apart and hope to take it up there tomorow. ill also have him clay it.

o ya. shortblock will do me just fine. heads are easy to drop on and the rest is cake

 

This might be a dumb ? but will the 408 still be good for towing?

I have thought about building one but I am not sure what the gas milage would be like or how well it would do with my trailer. Loaded my trailer weighes around 5500 lbs.

 

A 408 will out a tow a 360 any day of the week...ESPECIALLY if it's built for torque.

 

Does the computer need to be reprogramed for the 408?
Does it need bigger injectors?

 

got the assembled SB back today. he said the valves just barely even touched the clay.

im trying to find a .055 gasket to put quench at .040. the piston is .015 out of the hole. anybody know if felpro has one? the original head gasket mics at .055

 

The replacement felpro permatorque gasket checks in at .055 compressed thickness. I've had a set of dial calipers on it to check it before, LOL.
