I was also looking for a Holbay engine on another forum, for my Humber Sceptre MK2, until after much consideration and false alarms, I decided to keep my original engine and have it 'fast-road converted'' from 88bhp up to 130bhp, by doing the following:-
1. Re-boring the piston to bigger size. 1725 to 1850
2. Flat-top pistons to fit (for greater compression)
3. Twin weber carburettors (40 DCOE) + Sytec linkage cable.
4. Cam made into H120 specs (by http://www.kentcams.com)
5. Bigger harder valves (for unleaded petrol & more HP)
6. A lightened flywheel.
7. Fully Balanced.
8. Optimised on rolling road.
That should take me from 88BHP to 124-130BHP.
You could covert your Vogue engine to 1725 by re-boring it, then all of the above. But you will need to find a racing specialist who knows how to do it.
You will probably have to source the twin webers yourself from Ebay.
Tell them you want 'fast-road' and not racing specs otherwise you'll have an engine that is a bit temperamental.
