Stef's does nice work. There is also Hamburgers, Moroso makes nice aluminum pans (but I've only seen custom ones from them) and probably many others.

That being said I have not had much luck getting an aluminum oil pan on an iron block to remain sealed for any reasonable length of time. Tried all sorts of gaskets & sealers and on street cars eventually they all start leaking. I no longer even bother with aluminum pans on street cars since they always result in leak complaints. On a race car that's torn down and the pan resealed a couple times a season they're OK. Just my opinion here.

Now an aluminum pan on an aluminum block is a different story, since the thermal expansion is matched they stay sealed as well as a steel pan does on an iron block.

Another thing you need to be warned about is the vast majority of these fabricated aluminum pans are intended for drag racing use only and do not have proper baffling inside for cornering and braking. A friend runs either a Hamburger or Stef's (I can't recall which) aluminum pan on the 377 SBC in his Chevelle and under moderately hard braking his oil pressure goes to zero, the pan has absolutely no braking baffles of any kind in it, only a windage tray and anti-climb shelf at the rear of the pan. Drag use only! It does look good though. It's also a leaky SOB, started leaking pretty badly after one summer of weekend driving.
