That depends. You should select the pistons and heads at the same time to get the desired compression ratio.
Also, you buy a set of heads for a specific application, generally to achieve peak performance in a specific rpm range. If you are not skilled in this area, knowledgeable retailers such as Summit, Jeg's and others can help you select the right parts.
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
4.040". The standard bore is 4.00".
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.
4 to 8 degrees before top dead center
If the block has been bored and honed with modern equipment, you should have no problem getting moly rings to seal properly. Iron rings seal faster, but don't last as long.
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.
YES, A 355 is just a 350 bored 0.030 over very little difference.
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
Why 400 heads? They are notoriously bad flowing heads without much modification the engine would be about 360 cubic inches, but the heads have nothing to do with the size of the engine.
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
Depending on your intake system, you should be anywhere from 360 to 380.
Depending on the piston type you are running, you would bore .030, .060, .090. Or, .020, .040. At .030, you come out to 355. So, at .060, 360.
