3.48 inches.
The Bore of a 350 cid engine is 4.00, the stroke is 3.48 inch..
4.001" Bore with and 3.48" Stroke would make it a 350. Thats if it was kept to the factory condition. 4 Bolt Mains
Primarily the bore size. The 305 has a bore of 3.74 and the 350 is a 4.0 bore. They share the same stroke on the crank. And no, you can't bore a 305 to a 4.0 bore.
4.00 bore 3.48 stroke
The bore and stroke is different, But if you set the 2 side by side they will look the same other then some 400 engines have an extra freeze out plug in the side of the block that the 350 don't have. 350 bore and stroke is 4.000 bore,stroke is 3.480 400 bore is 4.125 and stroke is 3.750
A 4.060 bore with a 3.75 stroke is 388. A 4.060 bore with a 350 crankshaft is 360. yes the cubic inches of a Chevy small block with a 4.060 bore and a 3.75 stroke would have 388.4 cubic inches of desplacement however if you have a 4.060 bore and a 4.00 inch stroke you can have 414.3 cid but you have to use a 5.850in connecting rod for clearance of the counter weights
4.000 inches -- same bore size as a Chevy 350, the difference is a 327 uses a 3.250 stroke and the 350 uses a 3.480 stroke.
no. the bore and stroke are as follow the 305 3.736''x 3.48" and the 350 4.000"x 3.48"
The only thing special about the Vortec is the heads -bore and stroke should be the same on all 350 blocks. Cam is probably different though.
327 Chev smallblock bore is 4.00"/ Stroke is 3.25". Just to compare , a 350 is 4.00"/3.48"
NO The bore and stroke is different.
Im not sure the maximum but I think you can bore out to at least 361.
