    Just curious what the differences between a long and short block engine was. Just dreaming while looking at some crate engines, and it came up.

    Most "longblocks" aren't completely complete. They vary in degrees, but usually you'll still have to get an intake, carb, distributor, water pump, etc. for it. But yea, the easiest way to remember it is like the other guy said how longblocks have heads and short blocks don't.

    Thanks, thats easy to remember. I thought that it was two differnt small blocks,,,,one being a little longer than the other, but then I got confused b/c I never heard about long or short heads, which would have to be different for the different blocks. But now I can throw all that away. Thanks guys.

    I bought a longblock 2.8 V6 from one of the "Engine Exchange" places a while back, and the damned thing didn't come with a timing chain, plus it was missing a pushrod. Real good quality control, didn't surprise me at all when it spun a rod bearing at 1200 miles, and another one at 1500.
