2015年4月11日 · Big Block Chevy Cylinder Heads Open vs. Closed Chamber - A good way to describe big-block heads is to categorize them as open or closed chamber. Closed-chamber cylinder heads have small combustion chamber volumes for high compression ratios, with even mildly domed pistons.

2019年12月4日 · A 4.00" stroke crank or 4.250" stroke crank from the aftermarket with a 6.385" long aftermarket rod is a common thing with any big block Chevrolet, regardless of bore size. They easily fit in the blocks when using a steel connecting rod. Custom pistons are probably necessary with the 396 bore size so, you will need to put together you own combination for this.

2014年10月24日 · There are a lot of real fast cars with closed chamber heads, and a lot of real fast cars with 396 based engines. One thing you can do to help a 396 based engine, especially if you use the Edelbrock head, or one like it, is to notch the top of the cylinders the way Chevy did it for the 396/375, and then use a set of Moroso 0.030" offset dowels ...

I am thinking about building a 396 cube small block.How come they are not as popular as the 383.How much more does it take to install the 3.875 stroker in the 350 chevy block.I know you need .900 base circle cam and the correct rods.I'd be using brodix track1 heads and a solid roller cam.The goal would be around 500 hp with 11.5 compression for short street rides ...
