Default Ls next build

Anyone got recommendations on oiling setups on my ls next build
15:1 Comp solid roller dart ls next block
Tunnel ram twin carbs
Mellings oil pump for moroso wet sump
Should this oil pump be ok in this combo
Or should I go external wet pump or even dry sump
Cheers

What kind of RPM do you want to turn? I'm giessing it's a drag race application?

It's occasional drag and events setup
Max revs should be 7500-7600 if combo is right

You can get away with a wet sump setup at that RPM. A Melling pump with a Moros pan would be a good combo, I've got the same going into my 440ci build. The Dart LSNext block has different oiling so you can probably use a 10295 and be okay depending on your clearances.

Yeh I'm thinking wet sump should be ok
I have an accumulator also
The ls next block with the priority mains and stepped oil galleries should help
I also have restricted pushrods

I have a LS next 427 twin turbo. Turns 7500 using Moroso pan and 10296. You probably don't need a high volume oil pump because the ls next is so much better than its GM counterparts at oil usage. I used a high-volume because I also feed 2 turbos and an oil cooler.

Hope this helps.

Does anyone have any pictures of the oil filter location and feed line for turbo on the ls next blocks?

I went with a Dailey Dry Sump on my build and got 15.5" of Vacuum
as well. That said if using an internal pump I would have it ported to
reduce/prevent cavitation, 7500 RPM is pushing that design envelope
IMO.
