the pistons are the same diameter. no they are not the same diameter, the bore on a 305 is smaller than a 350
NO they are to big.
no.
All the dimensions are the same, but it should be re-balanced for the lighter pistons.
Not really. Exterior dimensions are the same, and everything bolts on the same, but the bore is different which requires different pistons.
yes, a 305 and 350 utilize the same block
305 and 350 share the same stroke, so that doesn't change the size of the engine. Installing 60 over pistons would increase the displacement by 12 cubic inches.
No. Standard 350 engines have 4.00" pistons, standard 400 pistons are 4.125".
actually yes, granted the wiring harnesses are the same a 305 engine block is the same size as a 350 the only difference is that the 305 pistons are smaller and few other componenets internal but the bellhousing on the trans will match up with the engine block
They are basically the same heads, If the 93 350 is a vortex motor.
You will need to have the heads for the 305 bored out to the same size as the 350. I disagree: you can use the 305 heads on the 350 block but you will increase compression as the 305 heads have a smaller combustion chamber. The critical dimension is valve clearance. If compression ratio is a critical consideration, different pistons may be available which will bring the combustion chamber back to size. the 305 is from the 3.671 inch bore family. The 350 is from the 4.00 inch bore family. All small block heads have the same bolt pattern.
NO the first has 305 cubic inches and the other has 350 cubic inches
