There would be 4 pistons, one in each cylinder.
They are the same as the EJ22 4 cylinder pistons. They can be purchased from numerous aftermarket resellers if you want forged pistons. Cast pistons would be from the dealer, if even still available.
Dome Pistons are used in 2 stroke engines.
If the pistons are hitting the crankshaft, either you have1. the wrong pistons (350 pistons are relatively short butit is possible to purchase pistons with the same bore but a longer skirt... in which case they would hit the crank)or2. the wrong crankshaft with too much "throw"

The pistons are running in the cylinders of the engine, so when the rpm of the engine rises, the pistons quickley build up speed. It is this rapid acceleration of the pistons that casue the car to shake.
Typically if the motor has been bored the top of the replacement pistons will have it stamped on top of them. for example if bored 0.30 over this will be on the top of the pistons.
307 pistons are 3.875" diameter. 305 pistons are 3.736". It might be possible to bore a 305 large enough to accept the 307 pistons, but the wrist pin location would be .230" off because of the different stroke. In short, no.

No. Standard 350 engines have 4.00" pistons, standard 400 pistons are 4.125".
The Pistons originated in Ft. Wayne, Indiana.
The support pistons need to be replaced.
