Dave--The LS7 dry sump engine has a pan, windage tray, pickup, dual oil pump, differant front cover, differant harmonic balancer AND a crank with a longer snout---

if you want to go the other way----after market---Aviaid has system and you don't need special crank or front cover/balancer---

If you want I can post or email pics of OEM stuff--I'll just need to dig out and photo all the pieces--
