Hi all, i'm trying to find a source for 4 qt. aluminum oil pans with out cooling fins for a 327 SBC with drivers side dip stick. the plan is to paint it to look like the stamped steel OEM pan. i could swear i'd seen one before but they all seem to have fins these days. thanks.
The marine aluminum pan doesn't look much like the OEM steel pan, does it? a few have sold on ebay in the past several months, none available right now. A boat place might have one?
Never been a fan of pans that can shatter if struck by road hazards.I"ve seen some badly damaged steel pans holding oil.
squirrel, that's a very neat old pan. i had a small boat yard starting in the late '60's and vaguely remember those. i'm looking for a pan like this without the fins. https://www.summitracing.com/parts/mrg-5415?seid=srese1&gclid=CIXWuo2m3-ICFXv34wcdbdUJrA
i'd thought about that since i'm going to paint it anyway. but being lazy was trying to avoid putting any labor into it since they're not very expensive if i could find one. wonder what the chances are of introducing stress risers from grinding off the fins? one of the raps on aluminum pans is that some are prone to cracking.
Far from it actually.... And a worthy point. I have had aluminum pans give me greif. I am a believer in steel pans. Sent from my Moto Z (2) using The H.A.M.B. mobile app
I have to ask, what would be your benefit to utilizing a aluminum pan over a steel pan? Sent from my Moto Z (2) using The H.A.M.B. mobile app
Cast aluminum rails won't collapse like stamped steel ones(possible leaks) same goes for valve covers.
^^^Possibly slightly better at cooling, extremely slightly^^^. Know anyone with a mill? Better than grinding, and definitely leaves a better surface. The only cast aluminum SBC pan I ever had, I gave away, and that was around 35 years ago. That red oxide primer aluminum pan looks like it might have been dropped. I am Butch/56sedandelivery.
You can’t say all aluminium pans shatter , it’s not right. Cheap diecast will, quality thick cast might crack but won’t shatter. The attached will bend but also won’t shatter. It’s about the alloy and construction method.
modern cars have been using cast aluminum oil pans for a long time...it's not a problem, if done right. And they can add rigidity to the block, also, if designed along with the rest of the engine.
The risk with a cast pan in a hot rod is if you hit a high spot in the pavement it may crack. A steel pan most likely will dent. I've seen it happen, so be sure the alum pan is protected. Phil
