So ive made a start, done a bit of a u turn and now im back to building this thing for myself
So i tore my block down
It had spun a rod bearing and damaged a crank journal quite badly but i was not sure if it was too far gone for a regrind
Also got my new forged spool rods with arp studs
I took my block, main caps, crankshaft and new rods to the machine shop im using and had a look over the items with an engineer, straight away he measured and sore the damaged journal had worn down by 0.5mm. Too far gone for 0.25 bearings we plan to use.
My block however seems to be ok, he is currently cleaning it up and measuiring it.
We did make some decisions on what to do with it, we are going to use the ARP main cap studs for a 4age engine to stop the main caps from lifting, and will be running bigger than standard bearing clearances.
Also we will use the 4age 10mm headstuds to stop the heads from lifting
So today i went and got another 4efte crank, which came with a free block

After removing the caps i discovered it too has suffered bearing failure and has damage on one journal, but it doesnt look anywere near as bad as my first crank atleast, oh well it was a freebie anyway, we will see when i take it to the engineer on monday, ive also sourced the arp headstuds and main studs so will take those to him also.
We looked at bearings and all he could find were taiho 0.25 bearings although he did prefer ACL
