Sure no big deal if you can fabricate or know someone. Not everyone falls into that category.
The oil reservoir is more than just a cylinder too. It has a mesh in it to condense the oil out of the vapor and whatnot. Not complicated, but not an empty tube either. I doubt many people are going to be making them out of scrap they have lying around in the garage.
Realistically, modifying the pan for AN fittings is a pretty simple operation too.
You're speaking from experience right? Having had the pan in front of you?
It doesn't look very weldable to me.
The oil ports are not a common AN size. They're 7/8", which would be AN-14, a size which isn't made. The openings are also recessed, and it's powdered aluminum, so determinging what alloy it's made from is anyone's guess. I wouldn't weld on it, and won't be on mine. I'm sure someone will try it, but I don't think it will be the walk in the park you described.
The better bet is to build an adapter piece (which is what we're doing), with the o-ringed press fit 7/8" tube on one side, and AN-12 fittings on the other. That way we won't warp the pan, don't have to worry about alloy compatibility, and it'll be reversible.
I guess the difficulty/price of the swap depends on how much you can fabricate yourself, or have fabricated for you for free/cheap.
You think? You just described every hot rod project anyone has ever been attempted.
I'm going to go out on a limb and guess that even with your connections you won't be doing an LS7 swap.
Of course, you'll have plenty of company considering the majority bitch about $4k motors being too expensive, I can't see everyone running out to drop the cash on an LS7.
Even a reluctor wheel swap isn't a particularly big deal, once you get past the whole tearing into a 13K dollar brand new engine part.
There are some other subtle differences here and there that will need to be addressed (like where you're going to put the alternator, since you have to use a Y-body damper, etc.). The cam sensor on the front of the timing cover supposedly uses a different shape than the LS2 does too. Lots of changes that add up for Joe average swapper.
A reluctor swap is $100 at Wheel to Wheel to have a 24x reluctor put on it. I won't be tearing into a $13K crate motor though. I have other plans.
And who the hell told you about my Aunt Roger?
