Post 2 dumb questions

first off when there are no bearings in your con rods (sbc) should the cap and the rest of the rod line up where the bearing would go or is this offset to hold the bearing in place?

Also at the back end of a crankshaft for my 400 sbc there is a flat piece... should there be a balaceing weight here or is this where it connects to the flywheel?

the flat piece is the counterweight, and the flywheel bolts to it, your rods have to be perfectly round when together, the bearing tangs ( the little notches) will be ofset.

umm k this rod and cap isn't perfectly offset... not sure if it is when it is tourqued but the cap seems to be sitting to one side the other thing is I swear I have seen metal plates that add on to the end of the crank (look like weights) maybe I am wrong though

there are metal plates that are added to the crank if you want to use a 350 flywheel on a 400. this makes up for the ofset weight a stock 400 flywheel has. I use them if i have an engine balanced. that way i can use a neutral flywheel.

Ohhhhh I see that helps alot... yeah cuz aren't the 400s the only ones that aren't internally balanced??? so I am guessing I need a 400 std flywheel then and I can't just use the one of the 305?

The rods are offest so that the wrist pin centers in the piston. This is something to watch out for when you are assembling the piston and rods. Some pistons are made to go in only one direction, and you have to figure out how the rods need to be put on the pistons. The bearing tangs should point toward the outside of the block. This puts the thick side of the big end of the rod toward the crank counter weights.

Whoever puts the pistons on the rods should know which way to do it right?
