Detroit 6-71 Parts

Claus, I think to myself that I should probably have those parts, because some day I may need them, but then reality sets in. If I were to take them, then in about 20 years, my kids would be placing an ad very similar to yours! LOL. Darrel

Actually I believe you could get a 71 in either inline6 or V6, believe they had 3, 4, 6, 8, 12 and 16 cylinders.  I believe the 53 and 92 were much the same way.


Gary, as for the water pump all I can tell you is give my Dad a call.

Have 453 factory in a 1962 Studebaker.

You can get most of the 2 stroke in an inline or V configuration

I guess I should have clarified my statement more. Steve is correct in what he said, and thats what I met, 12V71 is a one piece block(all I have seen, maybe someone out there has seen them different) but a 12V92 is really 12 v6's hooked together...

You have to be careful on the sleeves on a 71 series, they are NOT all the same size externally.  There was a factory ink stamp on the sleeves as they shipped them new, a mark toward the top of the sleeve was a tad bit light on dimension while a mark to the lower was a tad bit heavy.  A 'Standard' bore sleeve could be +/- .002, a .010, .015, .030 was the same for dimension stability.  I overhauled a great deal of the 6L-71, 6&8V-92 and a few 6V-53 in my career and only the 71 was a dry fit sleeve, the other two being wet liner around the combustion area.

If you install a 'loose' sleeve, one that falls easily into the bore it will fail at the intake ports under load or not transfer heat very well and gall piston to bore then tear the sleeve in half at the ports(can ruin a block).  If you have to drive them in they will gall severely in the first few hours of operation and then smoke the crank from excess pressure.  Been there, done that with too many guys trying to OH their own on the cheap.  We used a Sunnen Hone to fit the liner bores for the sleeves to fit a snug slip fit from top to bottom and required a intake port tool pusher to bring them back out.

I have several engines I OH'd years ago still plodding the backroads, most are not quality equipment enough for interstate anymore but set up just as described above.
I still have my liner stuffers(put pistons in from bottom of sleeve) to load sleeves/piston/rod at same point of time, for 92,71 and 53 engines.  Did OH a few 110's but too big and expensive to buy my own equipment, used a friends but he has long passed and the tools now gone.

looking for a muffler for 6/71 that bolts directly to head not mounted on exhaust manifold above engine.   exhaust exits top/ front of muffler.  used on HD15 crawler
