the LNF dipstick tube is different diameter and the boss is a different height compared to LSJ Buick also. I dont recommend running the LSJ pan in an LNF but if you do a simple tube modfication takes care of this should you wish to run the LSJ pan. Somewhere on here I posted the differences. I can also say I paid the price of a rod bearing not running a trap door pan with YYZ springs. The lap times were stunningly fast corner speeds higher, all left the oil pickup gasping for air.

I vouch for the trap door pan from Powell......have it and run many tracks and it works like a champ.......a great investment if you are tracking the car!
And don't forget the under car rails........and the rear bar.......

LNF and LE5 pans are the same; LDK and LNF are different. LDK is a inch deeper than LNF holds 6 litres and will not fit a KAPPA car which has a welded in cross member under the oil pan. Plus indicator tubes are different as I have said although they look identical they are not
this can lead to overfilling engine with oil if the tubes are mixed up which is a bad thing
I just make trap doors with new pans. The oil pan metal is difficult to weld also s,o we constantly look for ways to make them better

Please contact Gloria@powellraceparts.com with your zip etc so she can quote shipped pricing.
As detailed we now make these from new oil pans; the contamination of the alloy with oil makes a used pan problematical. Even so, the issue is welding on what appears to be a reasonably poor grade of alloy used to make these pans. They are made variously in Israel, China and Chekoslovakia (sp) so we are currently revising how we make these things. Sometimes its needed to use epoxy on the outer surface of the pan to seal the porosity that is happening during welding. We have experimented with many different accepted welding and welding prep techniques. Recently, making a radiator for a 70's GM 4x4 resto-mod we ran into the same issue.
What that means is I shipped the last LSJ oil pan yesterday, that we have in stock, and a new trap door pan series is in " production"; all our parts are pretty much ultra low production custom made.
MY orginal GM racing trap door pan made in 2005 I still have, but its a shelf ornament, as it leaks like craZy from the welds and is a colossal pita, even with an epoxy coated base. My Powell version happily doesnt leak. Not all of them do. Its the luck of the draw. Going forward I expect folks wont have to deal with it, as we will have found a new way to make these trap door pans.

yea that makes sense with the contamination. the metal always has to be clean as possible so I cant picture it getting cleaned enough lol. but ok, I will get in touch with her. thank you.

I tried to buy one last year I believe, ended up getting a refund as GM doesn't make the LSJ pans anymore. Other pans I can't speak for but as long as you or Powell can source a new one you can still have one made.
