MMMmmmm,,,,i`m not a big fan of em,,,for the very reasons given above,,,i can`t count how many i`ve seen pourous, &/or allready sleaved, , but the non pourous & non sleaved ones that i`ve found have been pretty dam good...just that i can actually count those ones & i can say that i`ve seen soooo many A+ donks, probly more than most people
the early 1100S (1275 non-sideplate) & 1275 moke blocks would have to be the best ever produced, & if you can find one , the early 1275 Clubman GT also, they were originally a side plate block just like the MK2 Cooper S , but after that short run they turned into non-side plate donks
I am a fan of the 1275 automatic blocks tho,,,,easy converted to manual & would have had very little stress ever & most are pretty stock bores still,,, if not maybe only .020 thou oversize,,,hee hee,,,perfect
OH!!! & to have an idea of what they look like,,,,the A+ engines have a huge array of extra "WEBS" cast into them,,,sort of Criss/Cross pattern of casting webs all over them & quite often have a breather catch can on their timing cover & &&&& los of other minor differences not really worth noting tho
But,,,when you think about it,,,you may well find that the earlier 1275 (1100S type) non-sideplate blocks will be getting much harder to find than the A+ blocks now days anyways & also even the A+ ones are quickly drying up in england too,,,so if you want a 1275, just don`t be too picky & get one before they dry up totally & people start charging even more than the stupid prices that they`re allready selling for now
There was once a time when i`d buy a complete driving morris 1100S (1275 4 doors) for $20,,, no kidding,,, $20 !!!!!! & that was only if they left the new battery in the car
Now i`m showing my age hey Doc
