Will do Bill, and if you sell to someone and they want to rebuild it, than I can do that as well, even resurface it and set it for use on a 948, if the person feeds me deck height info on their 948 engine.
Here's my train of thought when it comes to someone starting form stratch on rebuild of A series engine and they have a 948, or 1098.
948: They had the least stroke of all the A series engine, 3.000" so even when built for performance , they have no lower, or mid range grunt, you have to wind them up. Then when it come to rebuild parts, you will be greatly compromised at your choices, there are few people in this country and the UK, who do offer uprated pistons and such for this engine, but they are expensive choices. Pin drive cams don't grow on trees, so your choices there will limited, sure you can get your cam reground, but if you don't reharden it, then it wear quickly. Then there is the oil pump dilema, all the oil pumps, I have been able to find for the pin drive set up are later Mini stuff and that pump does not fit the old inline 948s, and 1098s, I went thru this with APT, and Mini Mania, APT offered a fix to fit the later pump to the older inline engine, but it don't work, not even close, so inthe alst tow 948s i built, luckily, the old oil pump were good shape and clearance properly, so I coulf re use them, sam ehting applies to the 1098 as or he oil pump. There used to be a Cooper S oil pump you could use in a 948 and then use later slot drive cams, but it seems to now be extinct. Then 948 only has one cam bearing, not the greatest set up in the world, racesr get the front and middle cam bores line bored for use of the cam bearings, but that expensive machining process, that not many machine shop can even do it. I've built a couple of hot rod 948, one with .060" over 998 piston, so in a 948 .120" over, making it a 1050cc engine and used 1098 rods. Bottom line you can start to see how parts are hard to come by, will cost you more, and at the end of the day it can put out no where near a stock 1275, even if perofmrance built. The last time I had to get a set of 948 rings for a Bugeye racer, we waited 3 months for them and paid double what they would have cost for the 1275. The 948 cylinder head, the valve spring retainer set up is an antique for sure, unless you scrap it all and uprade to later Mini stuff, then you have to use those silly oil splash shields, and not proper umbreall seals
1098: Ok, they did make improvements here in many ways, the bore on the 1098 engine, is only .060" bigger bore standard than that of the 948 standard bore, the larger displacment mostly came for more stroke, up to 3.300" now with the 1098, this gave the motor low end and middle power range grunt, so it was way more driveable than the 948. The 1098 in a perofrmance build has alot of potential, but there again part choices are greatly limited,and it still has the pin drive cam and oil pump issues of the 948. It hard to find a good , more modern pistons for this engine, although most vendor do have the stock, 5 ring piston avaialble for the 1098, this thing looks like it came from the WWII era
Bottom line 948, or 1098 even at a stock rebuild will always cost more to do, parts wise than a 1275, normally enough more to justify finding 1275 engine core for rebuilding, and there is nothing you can do performance wise to the 948, or 1098 that ifi you do the same to the 1275, that even makes them come close to the 1275 performance. There's alway going to be folks inth hobby who have a early car with 948, or 1098, that want to keep it original, and thats fine, it their choice, but if you are engine builder like me, you can see why I think that drivablity, and parts availablity on the 1275 is the way to go or so many reasons. I have buddy with an original 948 63 Midget, he loves it, but he might as well have a golf cart

, he will only drive it on very short drives, a beer run to the local store, and such, he scared to the death to take it on a longer drive. When it comes to rebuilding a engine and doing it right, it just makes way more sense to go with the 1275, you'll get way more bang for your buck. For the orrginal, I'm going to show it crowd, most of them have never even attend a concourse judged show, so what the prize for being original in a popular vote show? Of course this is the engine builder in me talking, I like a good bang for the buck, and the 948, or 1098 do not deliver on that promise, when compared to the 1275, but at the end of the day, each to their own.
The point of this post is not downrate, or belittle anyone with a 948, 0r 1098 engined car, but rather to open one eyes who is beginning into the engine rebuild phase of a project, if you like to drive your car, then the 1275 delivers way more for less money.
