What is a 030 over 350 engine?
That would be an engine whose cylinders have been bored .030" oversize and fitted with new oversize pistons. New displacement would be 355 ci.
What is bored over 90 mean?
That implies that the cylinders have been bored .090" oversize.
What does bored 30 over mean?
Each cylinder has been re-bored to a diameter .030" larger than it came from the factory. .030 oversize isn't much. It's done to correct slight cylinder tapering and to put the engine back into condition that it will last. It really isn't enough size difference to produce noticably more horsepower. Note that when the cylinder is bored .030 over, you'll also need pistons and rings that are manufactured to that size.
Where do you find the bore on a 350 engine?
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.

How many cubic inches is a stroked 4.6l bored .40 over?
It would only be possible to answer this question if you provided enough information, and in one system of measurement. What is the stroke of the crankshaft? Also, will the block be bored oversize by .040"? It seems unlikely that the intent is to bore a block .40" as there would be no wall thickness left, and .40 mm is .015" which would require custom made pistons as it is not an off the shelf size.
What size pistons do you need when boring 30 over?
30 over
Does horse power increase when the engine is bored 40 over?
Slightly. Adding dome top pistons would increase it more.
How many cubic inches is a 383 bored out 60 over?
A 383 Chevy is a 350 block with a 400 crank bored .030 over. If it's not bored oversize it's a 377 (Not the only way to make a 377). If it's .060 over, it's a 388. Most builders agree that you cannot safely bore a 350 block .090 over, but if you did the resulting engine would be about 394.
Doe's a 5.9 cummins have piston liners?
Hi 5.9 cummins diesels do not have piston liners. They have to be bored out and have over sized pistons installed. Chris
