I bought a chevy 350 motor and I put a 60 over bore on it can anyone tell me what its now cloassified as? I'm trying to make it a 350 stroker, and if thats not the way to do it. Then what does it take?

Lets math your question. To find the area of a cylinder the formula in pi = 3.14 x radius squared x bore x stroke.
Your bore = 4.060 x radius of bore = 2.03. square of radius = 4.060 x pi 3.14 = 12.748 x stroke = 3.480 = 44.364432 x number of cylinders + 8 total displacement = 354.91545 cubic inches.
Have fun with the formula.

A 60 over bore on a 350 Chevy is a 358. The only way to build a stroker is to install a crank with a different stroke than the block you are using from a engine of the same family. Most popular is a 400 crank in a 350 to create a 383. You can still use your block. Most times when you bore you do 30 or 40 over incase there is a problem later on and you need to bore the block again there is some material left. You are at you max bore now so if you ever break a ring and scar the cylinder wall you will need to get a new block rather than rebor and bigger pistons.

Due to your .060 inch overbore your 350 chevy engine would now have a displacement of 360 cubic inches. When an engine is called a "stroker", It means that the cylinder displacement has been altered by modifying the crankshafts stroke rather than just changing the bore size. Nowdays the most common way to accomplish changing the crankshaft stroke is by replacing it with entirely new aftermarket piece. Stroking usually requires pistons with a different pin location to allow for the added stroke, block clearancing, and also re-balancing of the engines rotating assembly.

It just makes it a bored out 350. To make a stroker motor, you need to change the stroke, not the bore. This is done by changing the crankshaft with one with a longer stroke. Most times, there is a lot of machining involved to make a crankshaft with a longer stroke fit the block.

Why would you need to build a stroker? Change the cam and put a set of fuelly heads on it and you'll have more power than you can handle!
