hey I'm in-search oh a 1725 holbay type engine to hot up my tired old 1966 singer vogue for my wedding in 18 months. any leads to the were a bouts of one is or something similar would be appreciated I'm in New Zealand so could make it harder. but any leads welcome thanks
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.
hi thanks for the tips i will investigate some more on that and have come to the same conclustion as you have said. i have a twin su carb setup on a griffths speed equipment intake do you know if that would be good?
