Robert

Yet another admission ~ I have never seen a "Stock Inline4 Vanagon" all the ones I've seen have been conversions & they all

have appeared to have most of the engine & intake & exhaust bundle to the D'Side of center ~ some I seem to recall even placed

the Alternator, P'S'Pump & ACCompressor all on that side. Unless the engine was squatty enough to sit straight up the portion of

the block that surrounds the Cylinders has to be mostly on the D"Side as well & don't leave out the Pistons, WristPins & a portion

of the Rods. Certainly the CrankShaft would be OnCenter & a portion of the Block & some or all of the OilPan would be to P'Side &

certainly the Batt' being on the P'Side back there would help but chances are in a conversion ~ & that is after all what this thread

is supposed to be addressing, the Batt' will be up front, on the P'Side for sure, but in the case of a Westy there may well be a 2nd

Batt' under the D'Seat that may just nullify that P'Side gain.

Take a look @ the "coming soon kit from FAS" & click on one of the photos to enter the gallery, then go to pic#106 ~ granted

they have @ least placed the Alternator on center & the ACComp to the P'Side but to the right of the ACComp there is a whole lot

of DayLight & if the Van doesn't have AC there would be even more. It does appear, in another pic, that the entire OilPan is on the

P'Side so that helps.

The VW guys may very well have had the balance in a StockDieselVanagon fairly well figured out especially for those places

where the Driver sits on the Right but ACButler wants to know about ConversionChoices.
