When I purchased my 89 SN the PO said the engine was replaced with a short block 351.
Can someone explain the difference between short vs. long blocks, and how I could determine which one I have??... Thanks for any help. ------------- Danny "no offense- but the rate at which you spread bad information is very impressive" |

Short means no heads. So it still has the original heads. ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing." River Rat to Mole |

A short block is a term for a replacement sub a**embly that does not include the Heads, a long block is an engine sub a**embly that includes the the short block plus Cylinder Heads and usually more.
They are not terms that describe the type of engine that you will end up with (like a small block vs. a big block), but rather how much of the engine was bought as new/rebuilt. So you have have an engine with a rebuilt/replaced short block and with the original heads if the PO is to be believed. So the valves/springs may be tired but the cylinders/rings, main bearings, oil pump, connecting rods, etc should be tight and ready to go for a long time. Not all short blocks are created equal, both in terms of what parts they include and in quality of the work, hopefully you got a good marine unit... ------------- http://www.correctcraftfan.com/diaries/details.asp?ID=1477 - 1983 Ski Nautique 2001 1967 Mustang 302 "Decoy" http://www.youtube.com/watch?v=cO5MkcBXBBs - Holeshot Video |

Thanks for the info.... 
The boat runs great...A little over 46 on my GPS with a four blade prop...  ...
I've heard those terms used over the years, just never knew. Now I do. Thanks again..... ------------- Danny "no offense- but the rate at which you spread bad information is very impressive" |
