Small vac port for running a vaccy advance dizzy..

Ports left undrilled, some of the other bodies had a breather port about 14 mm drilled. Some are threaded and I just screw in a sealing plug ( tapered thread)

Unsure if there is any coding to these numbers...

Original bores are 35/44 larger body goes to 35/52. Velocity tuning in the states modded bodies to 56 mm but pretty sure that business is now gone.
You likely will need to change some of the linkage for the throttle cable and can dump the switches if not needed.
Other bit of the mod is to locate an adapter or have the flange on the manifold welded so there is a bit of meat between the bigger bore and edge of manifold and the bypass port for the idle adjustment, they both run with very little sealing area to the outside of the manifold ( potential air leak later down the track ) Have to take a snap of the modded manifold on Valeries cabrio..

Ok thanks very much for you help I have brought the one you recommend here http://www.ebay.co.uk/itm/262392092218? ... Tags=bu=bu
