wasn't there a trick of using thinned down s rods on 1000cc cranks to get round the 'bendy rod' problem in old 1000cc miglias???
Hi, any idea what this entailed.? And any potential problems? Thanks

Yes, all the cool folk think along those lines..... :D

I'm planning an in-line 998, though at this stage if a decent ready built in line engine came up cheap I'd be keen, if only to move the project along a bit (though I'm skint!)

Should get the body back from the moulders within the week

I think the problem now is finding some small bore pistons with the larger gudgeon pins used with big bore engines/S rods? Miglia pistons were the 'thing' at that time but long since disappeared I guess. I would love to be proved wrong on this.

OK, so that's sorted then.

1098 Midget block (2" mains)
1275 crank + 6-bolt flywheel
970 S rods (thinned down and bushed small end) - sorts the 'pistons down the bore' issue
+0.040" 1098 pistons

What can possibly go wrong.....?

The good thing about that build is that it uses all the easy to find bits.

Good thing too, as I'm fed up tripping over those superchargers and Alloy heads, so it'll use up some of them too. :D
