Web Reg'd: Apr 17, 2006 THE SHADOW	Due to a few requests, I'll explain the difference: Long blocks: Wikipedia wrote: Long block is an automotive term describing an engine sub-assembly consisting of the following:Short block. The long block is always a superset of the corresponding short block. Cylinder head. A complete new or remanufactured cylinder head assembly is installed with a new head gasket and torqued to specification. Complete cylinder heads include new or reconditioned valves, valve springs, valve guides (if applicable), valve seats (if applicable), valve locks, and valve keepers. The bare head is free from cracks, warps, or holes. If the engine is a flathead, then the valve train is installed if the short block did not already have it. On most engines, the camshaft will be installed. On many engines with timing gears, the camshaft will be timed. Short block: Wikipedia wrote: Short block is an automotive term describing an engine sub-assembly. A short block is the portion of the engine blockbelow the head gasket but above the oil pan. A flathead engine will also include the cam and valvetrain. The overhead valve style of engine will not include the aforementioned parts on the shortblock. A shortblock is usually purchased to upgrade the water jacket, piston size or bore. Assemblies typically include the crankshaft installed and balanced along with the main bearing. A short block is considered destroyed when it either warps or cracks. Ignorance is bliss....305 fo life!...haha...Poser

nick06tc Reg'd: May 20, 2006 Scion Guru	Not to knock what people know, but GOOGLE can answer each and EVERY one of your questions. Web deffinetly knows his stuff, but What is a short and long block? can be answered by typing in long block into wikipedia. Takes about 10 seconds to find the answer he posted. The valve stem sizes can be found on tirerack.com. Forums are great for info, but most of it is just a meeting place for other info that is out on the net.
