2010 Grand Sport - no dry sump
Bought a 2010 Callaway Grand Sport. For some reason, I thought all Grand Sports had the dry sump oil system. Went to have my first oil change today....... and it does not. Any insight or information would be appreciated.

The reason convertibles are not dry sump equipped has to do with the location of the battery. In a dry sump coupe, the battery is in the right rear corner of the hatch. The 10 quart oil tank resides under the hood in the batteries normal location. The convertible does not have the ability to use a rear mounted battery. Hence, no dry sump.
Also, the dry sump cars have engines made by a single technician in the Wixom plant, with the Z06 and ZR1 motors. A badge bearing the technicians name is affixed to each motor. The crankshafts are different as well to accomodate the special oil pump used on the dry sump cars.

"The convertible does not have the ability to use a rear mounted battery. Hence, no dry sump."
What? What is the difference in the rear compartment of a coupe vs convertible?

Dr, I thought the same thing when I saw mine. It was a manual should have the dry sump. Didn't realize the convertibles didn't come with the dry sump. Hey at least our oil changes are cheaper.

Don't really know why the would put the battery in the rear for the 427 Convertible but not the Grand Sport Conv. Odd. Getting the battery out of Z06 was a pain, so maybe battery replacement under the hood might be more pleasant.

Thanks again to all that responded. Learned a few new things about the car. This is what makes this forum great. Have a great mechanic who is also a patient. He even called Callaway just to be sure, and came back with an entire car history based on the vin.

The GS vert is not rigid enough to pull the G's in a long corner to starve either side of the engine of oil, like the ZR-1 and Z06 the GS coupe will, hence the need for the dry sump. The 427 vert has the LS-7 engine, all the LS-7's are hand built dry sump only. Hence the vert with the dry sump.
The question to me is why the GS coupe autos don't have dry sump? In theory they could pull the same lateral G's as all the other models that require the the dry sump.

I have a 2010 GS Vert with an Edelbrock Supercharger and I had no problem relocating my battery to the right rear.

The 10 quart oil tank resides under the hood in the batteries normal location. The convertible does not have the ability to use a rear mounted battery. Hence, no dry sump.

I also thought all c 6 grand sports had the dry sump system. A friend of mine came by with a 2013 GS convertible. Had no dry-sump system and was a manual shift. First time seeing this. researching now.
Thanks for the info. Makes sense.

I still cannot wrap my head around the fact that decision makers at Chevy thought the multi-year Chevy "Real" People commercials were a good idea.
Back to the topic at hand, if I am not mistaken, the coupe, manual trans, dry-sump GS cars LS3 engines also have a forged crank instead of a nodular-iron cast crank.
