how far do i go

[HandyAndy]

Ronnie, thanks for the info, yes i agree that a contact with the local dvla is the way to go, thats what i,ll be doing as i have an office in my home town, i,ve been reading thru old posts/threads & this situation has come up before & basically the feeling is that the dvla inspection office is just to check numbers of supplied information given by the builder that for taxation class allocation that the numbers match, ie engine number ( engine size checkable) & chassis number before the vehicle can be taxed, & i presume the same applies to changing an engine, ie taxation class, tho i will be checking this out with dvla,

but then again with the new IVA regs there might be something in it about emission testing of new engine compared to the test of the engine as presented at the actual test, confusing yes but i,ll dig deeper & find out & post my findings on this thread.
all the best
