    Check out this interesting article, from Jalopnik, which highlights the biggest small blocks produced by Detroit.

    Small-block V8 engines are typically physically smaller than their big-block counterparts, hence the nickname. With some exceptions, the piston bores, stroke, cylinder head ports, and valves are all smaller than their big-block counterparts. That said, some small-block V8 engines are bored and stroked to rival, or even exceed, the displacement of certain big-blocks, although they remain in a more compact package. It's like the old jumbo shrimp oxymoron.

    Making the small block list are Chevy's 400 cubic inch engine, Ford's 400M and Chrysler's 360.

    These Are Some Of The Biggest Small-Block Engines Ever Built

    Where are our third-gen Hemis in this article? Chrysler and NHRA classified the 5.7,6.1, 6.2,6.4, them as small block engines because small blocks have the physical size that are similar to the small blocks. Plus, the small black vintage 904, 999, 727 and newer transmissions will bolt on to the back of all of the gen 3 blocks. I guess who ever writes the article is right?

    I want to see Mopar bring out a big block Hemi of modern architecture with 5.5" bore spacing, and a roomy crankcase for that 5" stroke some are going to want, especially in the IHRA.

    LOL imagine a 5.25" bore engine with 5" stroke.
    Imagine an 852 Hemi powering a Dodge Viper. (twice as much as a 426.)
