no mate, burton power dont supply them, ive got the tall block aswell, ive looked into it at lenght ie steel rods and forged pistons. specialised engines, where the block is from, can supply them if i remember rightly but when i spoke to them a while back they said the rods are bout £1200 on their own. theyre ones they get made, he wouldnt even tell me who makes them either but it wouldnt surprise me if they were made by one of the well known manufacturers though. another option is euro engines who can do a full rebuild with steel rods and forged pistons for this block as i rang them too.
most other engine builders can do the build too, jamsport can and also nms as they did it to previous owner of ryan_belfasts car who runs our block.
im still interested aswell mate if you find out any info.
