It would be 408.73 ci. 030 is typically all the bigger you can go safely. Some blocks will have too much core shift to even go .030. I would recommend a sonic test to determine the cylinder wall thickness & core consistency of your block. I've heard of 817 casting 400 blocks that had wall thickness almost equal to that of a bowtie block and others that could not even be cleaned up with .010 without getting too thin.

i have a 400 small block that has been through hell. it's bored 30 over. And old block. Its been a pulling truck for 3 years and now in a mud bog truck for 3 more years . and still going strong as ever and sounds great. just make sure you get heads that will flow enough air. becouse my 400 runs hot. im changing the heads and carb on mine.

The correct answer is 408.52712 cubic inches. Don't pay attention to these guys. A 400 inch motor with aluminum flat top pistons with Dart 49cc Platinum heads angle milled 23 degrees Victor Jr. intake and a 750 Holly and a nice 560 lift camshaft makes 586 horsepower it's a circle track race motor. I cheated a little. Do you want copy's of my dyno sheets? A 400 is not meant to be a screaming 8,000 rpm motor they are a great truck motor because of the torque at the bottom. Comp Cams has nice grinds for street use. If its apart have the decks checked for .000 at the top using one piston on a rod in the end four cylinders. Have your cylinder heads checked for flatness. If they aren't in spec. flatten them or if the chambers are over 65cc angle mill them to 23 degrees. Good luck with your project. 410 Chevy sprint car engine shops such as Kisler, Don Ott, Bob Kriner and Steve Kinser's own in house motor departments are getting 900 hp with injection and alcohol these days.

I don't like the 400 SBC. Siamesed cyl walls can overheat due to poor water jacket design. They had poor rod/stroke ratios so they were prone to breaking rods. I'd build a 383 stroker, put the 400 crank in an older 350 block with long rods and custom pistons. It'll live a lot longer.

Depends on the stroke Swept volume (bore area * stroke) * number of cylinders = rated capacity Assuming bore @ 4.125 " and stroke @ 3.75 " Standard capacity : = 400.921 cu in / 6569.922 cu cm With 40 thou (0.040") overbore : = 408.734 cu in / 6697.956 cu cm
