I looked at that car last year at PRI. I thought it had a iron block. There is plenty of room to get a lower compression piston in it. But, I like the idea of a spacer that fits into the water jacket on a iron block. So far really happy with my EEI block. But, I think there are lot of improvements I can make that the builder did not consider.

They installed a burp vent on the valley pan. Under pressure it releases through a filter. The engine builder said they installed it to vent and allow the dry sump to properly pull the oil out of the cam tunnel. It doesn't appear to work that way. The Arrington block I have has a plug with a hole in it to drain the oil out of the cam tunnel in case something failed. It also has a big hole with a screen epoxied in to vent the top of the engine with the bottom.

I just need to get the 358's rolling so I can go throught the 440 EEI engine and make it better.
