How can you see if the block is from ecotec models, or from c20xe models?
I am asking that because i know that the later c20xe engines was with ecotec blocks and some of them with black top cover.
My new engine is dizzyless '94 model and have the f20 gearbox and not the f18. (Some late c20xe engines was with f18 gearbox).
Also the engine number which is written in the block near the gearbox it starts with the word c20xe and then says the number.
Maybe i answer alone my question?
Or can i see from another way if the block is a ecotec type or not?
