I've sent two to three emails to Blainefab over the last year or so and I don't think I've gotten any responses back to any of them. Is he still in business?

SDPC is nearly giving me an LS3 shortblock so I think it may be time for his accusump setup just in case.

I don't know much about the stock 'Vette dry sump system. Is it undesireable for this use? The aftermarket ones are quite expensive but may be necessary.

And because I like scope creep almost as much as I hate financial responsibility, I've basically decided to dry sump it. Hadn't been able to get a hold of Blaine for a long time now and my best guess at adding an accusump was ~$700. The basic quote from Aviaid for a 3 stage system including everything except lines was ~$3200 and 4 stage at ~$3500. Since I already have the ATI damper that will pull the cost down a bit. Unfortunately I just haven't found evidence to make me comfortable running the LS3 on big Hoosiers and I would really hate to blow up a brand new motor. Once I set that up, the oiling system for the car is done forever and I never have to worry about it ever again. It's the X-Trackers of oiling systems!

I get it. As I've been looking at ideas for an engine for mine, I've found that the new Dart blocks have SBC style main caps that help eliminate the bottom end breathing issues that hinder oil return to the pan. I'm wondering if that's truly enough of a solution to consider the issue "solved". Otherwise, I've been eyeballing dry sump systems and wondering how insane it might be to try to hide a tank in a true street car (thinking I might run some events and maybe an occasional track day in it....once I weld in a 4 point).

I was also trying to decide what at 22k mile crate LS1 (factory installed at the dealer) is worth once I pull it out of my car. It does have some cold piston slap, but it runs fine. It was put in at like 42k miles. The car has 64k on it now. (or, so I stuff that one in a Miata?)

The stock GM dry sump is worthless. GM neglected the important part of a dry sump system, the scavenging from the heads and various points around the engine. The oil can still get trapped in the heads with the stock system. It's more of an external tank wet sump system. It's a hybrid with all of the worst characteristics of both. The oil is stored in a cool tank that may make it difficult to keep oil temps up in cold weather (less likely than being in the crank case), remote storage, additional lines and hoses, no oil scavenging from the heads, an internal "wet sump" style oil pump, etc. As far as I can tell, the factory "fix" wasn't a fix at all.

HUMMMMM ! .. I have been basing part of my "next car" decision on the fact that the manual 2012-2013 GrandSports use the factory dry sump, and the automatic cars don't (conventional wet sump oil pan) ... sounds like I don't need to care ?!? Just decide between 3 pedals (my bias), and paddle shifters (I think I'm getting old)
