Need big block help

Right under the plug wires in this area of the head, next to the manifold…….. it’ll say either “440EZ”, or “440EZ-1”.

Be interesting to know which you have there.

i'll look tomorrow but right now I think its Indy EZ. The dyno sheet was run with a carb not the EFI and the timing is locked out and set to 30*. When I'm done reconfiguring it'll be controlled by the EFI. I have FiTech on my own 340 and it runs well so I was elected (volunteered) to try and sort this one out. I thought the numbers were low for the cubic inch. I just dont like the RPM to go up when you drive away and not even be able to feel the shift under normal driving. That's why I mentioned the converter. The cam sounds a bit bigger than it's specs. Ill update. thanks again.
