thats my take on it too,

but while doing this some simple additions would be worth while, mainly the S removable tappet chests, but maybe leaving the headface undrilled to allow for 16 v fitmants.

I would of thought a block cast with a blank deck would be ideal. No need to piss around plugging holes in the deck for different head conversions and dry decking etc...

People can then drill the block as they please. You could sell a drilling jig for different head combinations also? There will come a time where old A blocks will be very hard to come by and this could be an answer to suit those who want a block for a "standard" build and those who want it for hybrid type builds?

I can't see the need for a 5 bearing crank at the moment...how often do you hear of problems with the crank?

hee hee Vegard,,, you always make me laugh

Matty,,, where have you been for the last 40 years? 3 Main crank whip/flex has allways been an issue,,, all be it less of a problem once a few things are modded, but still an age old problem none the less,,, a 5 Main would be just sweet & give heaps of confidence to rev past 10,000 if need be

Our Litre sprint car (well not mine but a friends) revs past 10,000rpms most sat nights & is still sweet after many many seasons of use,,, (Cosworth alloy block & Datsun 1600cc 5 main crank) i can`t see many 3 main engines able to show results like that... not that it would be any use to the average Joe/Jane Doe on the street tho

Problem with designing a five bearing crank and block is the A series close proximity of cylinders to each other. It will take considerable engineering and design to get it right, and who has that sort of money other than the Auto manufacturers.

Bottom line is, the a series block is a factory block, was designed, developed over 50 years and can withstand 300bhp. And, with the heads, yes the KAD head is a 'bolt on' conversions in that is uses the original head stud locations, but it is far from a production manufactured component. The BMW head on the other hand is a production head again seen millions of miles service on touring bikes across the world, parts are available from any BMW dealer, and has had the same sort of development and design the A series block had, if not more. If there is nothing wrong with the design of either the head or the block other than the head stud locations, I just cant see the justification to start making gear to overcome a problem that isnt really there. Granted it would be nice if some one started remanufacturing the A series block as is, but with a closed deck as Matty suggests, but a five bearing crank, it will never ever, ever happen!!

If you want an engine that has five bearings, can take pistons anything over 74mm, have sixteen valves and it be bolt together, find something else thats already been done.

If we all wanted a five bearing crank and block we would just look at the E series boat anchor!!

yup, i think a std block with a few mods would be ideal.
things like blank decks, improved casting to aid cooling, 4 bolt centre main as standard. Maybe even liners in a good modern material to mean an extended life to make the cost of a new block worthwhile.
Not only would you sell them, but then you would have the associated income from machining to certain specs etc.

What you could do would be casting up some blocks which would allow a different main bearing setup, ie a bigger one. Then, if you liked, you could get a special crank made which would have a bigger bearing overlap, higher resonant frequency and high rev potential....and then you remember it's just a mini.

A+ blocks would be a very good idea. I wondered what happened to the patterns/moulds.

I have a few A+ blocks in the back of my garage but in a few years, we'll start seeing them make silly money. Really silly money.

Bugger off, I'm getting there.

yoou can already tak the A to crossflow sized mains, gives a big increase in bearing overlap.

Heres a thought, if you were going to make a block, why not make the deck higher so you could keep compressions low??

Or is this just a shit idea?

Ps the E-Series weighs more than the world. Ive seen a mini with one and the suspension on the front was taking a serious battering

i recon blank blocks would be awsome, i know i have saved my self a few engines just in case!
