That refers to the cubic inch displacement of the pistons in the 350 engine.
yes when the engine is out and upside down
Depending on what the engine was used for, most likely dish top pistons. But flat tops ARE possible.
No, 350 has a substantially larger bore.
No. Standard 350 engines have 4.00" pistons, standard 400 pistons are 4.125".
A real LT-1 had a four bolt main block.
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.
Air intake leak between the carb and the pistons action. the closer the the carb, the more likely.
The stock 350 pistons have 3 ring grooves.The BOTTOM ring groove is for the oil ring assembly.
the pistons are the same diameter. no they are not the same diameter, the bore on a 305 is smaller than a 350
6 quarts.
350 cubic inch does not equal any horsepower. it is a measure of the size of the engines combined pistons displacements. in general a 350 cubic inch engine will make more power than a 305 of the same year and manufacturer engine but it really depends on how the engine was designed.
