A re-manufactured long block or rebuild existing engine

Rebuild, you will have greater control and know what was done.

My concern with a rebuild is that they don't seem to have much of a warranty compared with a re-man long block.

Look at it this way, it's like the difference between a custom built computer and one you can buy off the store shelf. The custom built machine has the parts you specified and you actually know the person who built it as opposed to a company that had a lot of different people with their hands in different phases of production. Forget the warranty, it's just a piece of paper. When someone actually hand builds any product, there's a certain pride of workmanship that goes into it.. it's like their signature on the end product. That is why"exchange engines" are never as desirable as a engine that was gone through with a fine tooth comb.

INSTEAD OF REBUILDING A MOTOR THAT HAS HAD METAL SHAVINGS INSIDE (VERY BAD) SCRAPING, DAMAGING THINGS YOU CAN'T SEE, FIND ONE THAT HASN'T HAD ANY METAL SHAVINGS AND REBUILD IT. THEN HAVE A GOOD SOLID CONFIDENCE IN THE PROJECT. OIL RUNS THROUGH A LOT OF CHANNELS AND OTHER HIDDEN AREAS. WITH SHAVINGS IN IT, A LOT OF DAMAGE THAT CAN'T BE REPAIRED. RISK PAYING FOR A REBUILD THAT STILL HAS SHAVING JUST THROWING YOUR MONEY AWAY. A LOT OF INTERNAL PARTS, SURFACES IN AN ENGINE YOU CAN'T EXAMINE FOR SHAVINGS DESTRUCTION WILL
