detroit 60 series engine block 11.1 to 12.7.

On a long lonesome highway, east of Omaha, you can listen to the engine moaning out it's one long song-Bob Seger-Turn the Page. The 92's were a popular bus engine several years ago. They had 92 cubic inches per cylinder and could be bolted together for a 12v or 16v configuration. I'd almost bet Mr. Seger was setting on top of a Silver 8V92, when he penned that song, back in the early 70's. Sweet sounding engines for sure. Back in those days though, Detroit's 800 number was 1-800-LEAKOIL, lol.

 

all 11.1 litre engines converted to 12.7 needed machining for top liner cooling then crank and rod change whether it was lightwieght crank or standard regards David

 

contact rebel 127 he can tell you just what YOU need to know, especially if you want to keep your 11.1 but have it run like a 12.7.

 

the only 11.1 I used to work on was bus... when it was converted to 12.7 I did ECM reprogramming to get more available power. really no mpg difference was notised

 

11.1 to 12.7 top liner cooling crank rods and injectors Regards David

 

The 11.1 liter series 60 is definitely an inline SIX, and the block has the SAME dimensions as a 12.7 liter.

 

correct except for the top liner cooling Regards David

 

just tune the juice to the 11.1

 

You really shouldn't be a smart ### when you are so wrong, it just makes you look more foolish. 11.1 L, 12.7 L and 14.0 L are all Series 60 engines (meaning inline 6 cylinder). The 4 cylinder is a Series 50 and is only 8.5 L.

An 11.1 L can be converted to a 12.7 L, but the stroke is different, so you need to swap cranks. It is not as simple as buying 12.7 L cylinder kits. The 11.1 has a 5.47" stroke, where the 12.7 has a 6.3" stroke. The bores are the same (5.12"). In the case if the 14 L, bore and stroke are both more than the 12.7 L (5.17" bore and 6.61" stroke).

To answer the questions of swapping in a 12.7 L, it is the same exact external dimensions and will bolt right in place of an 11.1 L.
