430 Into "64 LeSabre Oil Pan??
Hello everyone,
I have an opportunity to possibly upgrade to a 430 from my original 300 2bbl! I am about ready to make the leap as I have come across what I believe to be a good candidate for the swap...my question is in regards to the oil pan. The seller of the motor mentioned that he doesn't think the swap is possible due to the drag link location in my LeSabre interfering with the 430's oil pan. I have been trying to do my homework and have learned that there are rear sump and center sump pans for the 430. Which one, if either, could I use on the 430 to clear all of my steering components? Anyone out there put a 400-430-455 into their LeSabre that can give me some tips/advice? As always, thanks so much to the knowledgable people on this site!

I'm hot to do the same swap.
I've got a 65 2 Dr hardtop and I started down the same track. The 300 is a very small center drop oil pan and the 430 Rivieras were a center drop pan but too big to fit like 3 inches. I have a rear drop pan for a 455 (will fit a 430) but my guessing is its not far enough back to clear that center link.
Big buck solution is a Flaming river rear steer Rack and pinion for a 65 Impala $1200+ with mount which would still need minor mod to go an Buick.
Where are you? Sounds like we should work on this together. I'm in So. AZ. I posted this problem about 6 months ago and didn't get much response.
When Buick made the Wildcats they used the Electra frame with the LeSabre body firewall back. So the front fenders are 3 1/2 in longer, hood is different, and they got the extra space in the eng compartment. I'd like to hear from a Wildcat owner about what pan they have and where it fits the steering. Of course those were also nailheads so it may not apply.
For right now I've chickened out and found a Aluminum heads and 4 barrel manifold 300 and will distract myself fixing that until I can get more solutions on the big block swap. I have a 69 Rivi to take radiator, A/C stuff etc out of. I'm thinking depending on how well your 430 engine is built and how you drive you might want to think about a stronger rear end, at least a posi conversion into a 8:25 which is available for the 65.
I'm running 800cfm electric choke Edlebrock Performer on my 430 Rivi and love it. Made it a new car from the "re-built" Quadraflood carb by Noah.:shifter:

I'm considering the possibility of getting my hands on one and comparing to the overall size and shape of my 300 pan. The thought I am having is wether or not it would be feasible to do a little cutting and splicing. The idea would be to use the Rivi's 430 pan but cut the drop portion out and either fab a shorter drop to weld back in it's place or cut the drop from the 300 and weld it in. The question, I suppose, would be wether or not the drop would be in the correct place to clear everything even if made shorter (shallower) and then just modify the pick-up to fit the custom pan. Let me know your thoughts on that, you too Dr. Frankenbuick (and anyone else willing to chime in) if you don't min
On a different note, I am also considering the option of just rebuilding the 300 I've got in it now. A couple of things are making me a little hesitant to do so. First, there just aren't a lot of parts or options available for this engine. Especially my '64 aluminum head, 2bbl version. I'm not looking to make this thing a hotrod or anything, I just need reliability with decent torque/power as it is my daily driver. No one even makes or even rebuilds the crazy motor mounts! The second thing holding me back on the 300 is that I don't want to spend time/money/energy going through this motor and rebuilding/replacing (not to mention finding) parts. And when the smoke clears, I've still got a low compression, 2bbl, small displacement engine pushing around my huge 4 door cruiser. And if/when something breaks or wears out I have to hunt all over again.
ATTENTION
I don't think it's just a depth problem. I'll go get measurements. 430 Riviera center drop is longer and wider than 300. Wider doesn't matter but longer does a bunch, plus I don't know how much fore aft move there is in the center link as you steer. I also contemplated cut and weld, but the drop is there to add volume of oil for big block and to fit the big pick up screen. I haven't compared pick up screens as yet because I haven't taken pan off 300.
WHOOPS SCREEN SCREW UP THOUGHT I WAS AT END
Sorry to write a book, but when I consider all of these things, it makes the 430 option seem like a no brainer even with the mods and fab work that it might require. If I could get my hands on a '64 aluminum 4bbl intake for a reasonable price, it might sway my decision a little more to the 300 side, but as it stands I'm leaning towards the 430.
Hey! Anybody got a good running 401 or 425 Nailhead just sitting around they want to donate to the cause?! :bgrin:
My motivations are similar to yours but at heart I'm a hot rodder and I want it to smoke the tires while being a reliable driver.
Still didn't say where you are? Would make logistics for joint projects possible or not.:hurray:
