Can anyone help regarding the above engine, I have had an e-mail from a friend of mine in Australia asking if I can shed any light on it for a restoration which is under way.

Gilford didn't make their own engines but bought in from outside suppliers, so this engine was actually made by the Buda Engine Co of Harvey, Illinois.
The PSVC published a Gilford chassis list a few years ago, according to which the Buda engine option in the AS6 chassis was the ASB model, and it gives the following specification:
6 cylinders, 3.625" bore x 4.5" stroke = 4568cc. "Nominal hp" (I guess this means the RAC rating) = 31.5hp, actual power output = 85bhp.

I’ve been looking on the web about this Buda engine and found a thread which seems to indicate that it is a not a Buda engine at all, but a 6-cylinder Lycoming ASB engine which has an Imperial (identical) bore of 3 5/8” and a stroke of 4 1/2”, surely too much of a coincidence! And, from what Michael W says, the option was the Buda, with, perhaps, the more common Gilford engine fitted being a Lycoming. The link is www.smokstak.com/

According to the PSVC list, the only other engine option for the AS6 apart from the Buda ASB was the Coventry Climax L6, which was a copy of the Lycoming 6TS made under licence.
Interestingly (and a little suspiciously) some Gilford CP6 models were fitted with the Lycoming 4SL, which was a 4-cylinder engine but its bore and stroke dimensions are identical to the Buda ASB.

I originated the smokstak search because 1) I am researching Gilford because of a family connection, and 2) I was trying to assist Malcolm Skevington who is restoring AS6 DX9547, and ideally would like to find a spare engine. I have recently been sent some gasket drawings and on comparing them with photos of the cyclinder block appear to confirm, contrary to the data in the PSV circle book, that the engine is indeed a Lycoming ASB. The engine in DX is the same as that in the other surviving AS6 and also the DF6. Malcolm is going to do a final comparison against a gasket removed from DX which I believe will yield the final confirmation and I will report the outcome.

The final definitive proof has now been received. I have seen a picture of the removed gasket and it confirms the engine as a Lycoming ASB.

Thx for confirming the type of engine it was. Lycomings were certainly the most common engine make fitted.
