That would be called a Chevy 307 bored .40 over.
a 357 Chevy is a just a smallblock 350 Chevy bored .040 over for a total CID of 357, just as one bored .030 is a 355 Chevy. a standard rebuilt 350 is generally bored out during the rebuild process to usually 355, sometimes 357. right now i have a 357 Chevy in my 1970 chevelle
A 350 bored .040 is a 357http://users.erols.com/srweiss/calcci.htmThis will help you properly calculate CID.If you are using a different crank, rods, you are creating different values that need to be taken into account to be calculated - so notate all of that stuff and do you math correctly the first time or you could run into problems.
Here's quick easy and simple answer 350ci is the total volume of all eight individual cylinders of the engine in cubic inches added together 350ci divided by 8 = 43.75ci volume per cylinder bored .040 over which means forty thousands of an inch overbore means that you enlarged the entire bore from top to bottom by forty thousands of an inch over it's entire circumference the reason it is done is because the cylinders have worn to the point that even with new piston rings the tolerances would be out of factory specs. so you bore it out .040 then you have to buy new .040 over pistons and rings then do everything else you need to do to put the engine back together and you have a Chevy 350 bored .040
4.040". The standard bore is 4.00".
If my math is correct , almost 410 cubic inches ( using a 4 inch bore and a 4 inch stroke that has been bored out .040 )
It's a 327 with cylinders bored .040" over stock.
4 to 8 degrees before top dead center
How much hp should I get out of my Chevy 350 bored .040 with six inch rods shaved block and heads. I'm running a 500 500 lift cam with 106 degrees of lobe separation
Yes it does. Boring it at all has an effect on it. However, a .040 overbore won't hurt anything. Most blocks can easily handle a .060 overbore, so you should be just fine at .040.
