How far can you punch out a Chevy 400 Small Block?
You are better off stroking it. The 400 has 4, and 1/8th inch bore. It also has siamese cylinders to accomodate the larger bore. And, the water does not use water to cool. It has steam holes, as the cylinders are too thin to run watrer, so, remember to have your cylinder heads drilled out for the block. To bore that motor, you would have to sleeve the cylinders, then bore them out. Very expensive.
How big can you bore a small block 400?
A small block 400 engine can typically be bored up to about 4.155 inches, depending on the specific block and its condition. However, the maximum bore size may vary based on the manufacturer and any previous machine work. It's important to consult with a professional engine builder to ensure the block can handle the increased bore without compromising structural integrity. Always consider the potential for overheating and other performance issues when increasing bore size.
How do you tell the difference between a 350 block and 400 block Chevrolet?
If the heads are off, you can measure the cylinder diameter. A 350 has a 4" bore, a 400 has a 4.125" bore. Also, a 400 has two small steam holes between the cylinders. If the engine is still all together, the balancer is different. A 350 balancer is smooth and even all the way around. A 400 is externally balanced and looks much different, with parts of the balancer looking like it has been cut away.
How much do you have to bore a 383 to make it a 400?
A 383 is a 350 block with a 400 crank. The block is bored to 4.030". A 400 has a 4.125" bore, so you'd need to bore the 383 roughly .095", which is probably not practical as the 350 is not made to be overbored that much.
