Another I vs E Thread.. Sorry

[Cory1970]

looks like a flat piston = eta bottem end

and #200 head = eta head

Eta's do not have flat top pistons , they are dished

Although it is difficult to tell from the borescope's pictures, the pistons did appear to have a shallow dish on the screen. To my knowledge, the I pistons have a much deeper dish with larger valve reliefs.

what you say about s-etas is true, but he has slightly dished pistons and a 200 head casting. Regular eta short block.

he may have a s-eta DME running it with "i" electronics
