Here are the latest pics of my engine rebuild for those who are interested. Did 90% of it myself with the guidance of a couple of people in the know.
Stripped the engine right back. Checked and reused most components as they were only 20 000 kms old (since it was last rebuilt).
But this time i did everything how it should have been done! Crank linished, ACL bearings, bores brush honed and re-ringed pistons, ALL gaskets replaced, heads were milled 85 thou', intake manifold matched, pistons flycut, heads fully rebuilt with k-line guides, new valves, new stem seals etc. Heads were ported and only exhaust ports were polished, the whole intake system was carefully match ported all the way through.
I know what some in the know may be thinking.... Why stay with stock pistons? Well the dish in them is really SFA, and (to me) not worthwhile investing in flat tops. So instead i bumped up the CR via the heads. Not everyone's cup of tea but i don't care, got some very reliable advice from an engine builder from speedway.
Anyhow, here are some progress pics. It's now in and running in :w00t:
