I use a Milodon dragster pan with the kickout (no starter) , Aluminum pans are OK but if you do something that makes them start to leak, harder to find a tig welder at some tracks, but can always find a torch rig. 2" is minimum oil pan clearence, must leave room for either the tray or diaper

Milodon 31145 is popular and works well--I am guessing you have a two piece rear seal block--I would ask Jim that sold you the engine--he may have others he could sell
show a photo of the pan you have that will not work---what is depth at the rear? That way you can compare to ones you want
Milodon also makes a pan with a kickout which usually makes a few more HP but big deal you have an engine that went 5.20's so it is Plenty strong!! and that kick out pan is expensive
Let's see what you are working with and we can help

I`ll give the exact measurements later as i dont remember them at the moment (and im not at home now).

The oil pan on the engine is very similar to this:

Going to have to raise the engine or go dry-$ump, Bottom of the pan and oil pump/pickup will be a problem if you go with anything shorter than 7 1/2"

Do you have a torsion bar on the front? Maybe you could raise the front some.

Maybe you could turn the front axle upside down :o

No adjustment on the front...
I'll find a solution to it. I found one locally that might actually work, i need to doublecheck exact measurements.

They used a 31145 in my car when it was in USA.
BUT, there is always a BUT..., if im not mistaken, my engine block has a right hand dipstick  >:( (Im rushing home from work soon to confirm as i havent paid any attention to it before)
31145 is left hand only, and i cant seem to find any with the same depth for right hand. Cut and weld?

I hope im wrong though..

Right hand DS block uses a one piece rear main seal, older 2-piece seal is a left hand DS block,
 Milodon #31173 rt hand DS w/KO
Milodon #31147 is without KO

It is right hand dipstick and two-piece, just checked.

SBC's 79 & later are right hand DS -  one piece seal is 87 & later.

Dip Sticks ??, Do race cars have Dip Sticks ??
We dump our oil after each event when we get home, cheap insurance. I have talked to a alky burning racer that didn't drain his oil after a race week-end and let sit for a few months [Winter] and was surprised to see rust on his iron heads and block, because of the alky in the oil. Alky attracts water.

Have Fun !

Hi Jon, no i dont need a dip stick, but i was thinking the pan would need to be modified to fit the block if i use one for left hand DS, and that is something i would not rather do myself.
