Can anyone tell me if a 1979-1982 vintage t140 head will work on a 73 T140 lower end? They both are 10 bolt units but need to be sure.

Thanks

This forum is for the 2001 and later Bonnevilles, and though someone on this forum may be able to answer your question, you would probably get more and faster results on another fourm.

Look on the left side of your screen at the listing of the forums. Click on "Classics and Vintage" and scroll down a ways in that forum till you find the Meridian models and click on that forum. List your question in that forum and you will probably get a quick reply.

OK you classic guys, it's your turn - we were crap!

All 10 bolt should work together. Perhaps a specific set of pushrod tubes may need to be used.

They will bolt up to the cylinders and run fine but the carburetor manifolds are different (and I think the air boxes are too) on the 79-82. The Manifolds on the 79-82 heads point straight back instead of being splayed outward and the carbs are held on by rubber hoses instead of being bolted solid to the manifolds. There is no provision to attach the earlier carbs to the 79-82 manifolds. If you're building something this might not be a problem but if you are installing it on a stock bike and planning to reuse your existing equipment (carbs/airboxes?), it will.
