Thought I better share,a little bit of horse trading and I ended up with this early 60's build 312 this weekend.
std bore 312
Ported and polished "G" heads
deep sump pan
Everything looks very unused,very tight timeing chain,clean bottom end other than mouse house causeing some discolouration on throws.Also mystery cam that's I have not pulled yet.
Finally feel like I have something of interest to share to group.
