I'm putting in a 406 small block in a 1987 IROC this summer, and i was wondering what oil pans choices are available. I know the front crossmember between the lower control arms limits the size oil pan to stock volume. On the other hand, i can't seem to find a stock volume oil pan that will work with a 3.75" stroke. Any suggestions? Any and all help is always appreciated.

 

The Kmember does not really limit you that much.

I run a summit 7 qt. kicked out sump pan in my 1988 camaro. My dad has the same pan on his 1982 firebird.

Both has stock K members.

I posted pictures on another thread, take a look at my post on this thread https://www.thirdgen.org/forums/tech...se-hooker.html

 

Back when I had a SBC in my car, I ran a 7qt Moroso pan with a stock k-member with no clearance issues.

Pan volume is in the sump. There should be very little oil at the front of the pan so a deeper pan at the front is not required. It only needs to be deep enough to clear the crank and rods.

 

That's great to know, thanks guys. Any part numbers on those oil pans? I'd like to look at the prices

 

The pan I used $79.95 http://www.summitracing.com/parts/sum-g3502 and of course you have to buy/install the longer oil pump pickup on your oil pump
Which I used the summit brand $17.97 http://www.summitracing.com/parts/sum-g3502p

So $98 total

 

FWIW, on ebay there are deep pans available for either 2 piece or one piece rear mains with the pickup included. I have one on my '86 and the problem I had was the starter was rubbing on the bigger pan. Got a small gear reduction starter from the same seller for cheep and they both work great! No leak's and the starter whirr's my engine over like it's a low compresion engine, and I'm at 12.5-1.
