After many hours of troubleshooting my 62's under performance, eventually had a compression test done ...... seems I'm running a 4 cylinder version!

Wow, that would do it.

 

[Tinker]

Did they do a leakdown to tell whether it's rings, intake, or exhaust valves?

What is actually wrong with cylinders 1 and 2?

 

[hightide]

how is the SOA going?

 

[chief]

When adjacent cylinders are low like that often their is a problem with the head gasket between the cylinders which does not involve the waterjackets thus their is no water leakage or overheating problem. The gasket is merely blown between the two cylindersletting compression leak into the other cylinder.

Exhaust Valves on #1 & #2 were burnt. In fact the valves were actually warped, as can be seen from the chart, #1 did not even hold any compression.

The SOA is mostly done, been refining the steering and bits & pieces. Had one test so far, really happy with the performance, especially the 4.88's with the 5 speed and 35".

The steering has now changed after bending the drag link. Due to not being able to buy a hysteer here for a RHD, I manufactured my own semi-hysteer by welding another steering arm upside down on the original one.
