Hi and thanks all for great welcome, Goodwood was a great day out, planning to go again this year

The tractor is a David Brown Cropmaster, now running but having some fun with oil pressure....thats another story!
The engine plans arise from trying and failing to fit the tb's under the bonnet with the silvertop, plus a few other bits, and having trawled the various threads on this forum I have decided to go with the new omex engine and TB route, RTCC are talking with Omex to try and source the shorter Jenvey bodies as the Omex made bodies are I think now longer than the earlier ones they bought in.... Hoping to hear in next week or so and get the work done for May.
The Librands manifold and exhaust definitely improves performance significantly as many have said, however I have found an intolerable drone from about 1900- 3000 rpm, which unfortunately on the roads around here is a lot of the rev range when touring.... And sometimes no amount of gear changing can seem to shift it... Hence decided to keep manifold and cat and swap the system back. I read someone on TM has done similar and found no noticeable difference in power.. Henc going to try this.
Cheers
Steve
