Can someone tell me what the difference is between the E6SE and E7TE roller blocks? I have personally seen E6SE blocks in cars and E7TE blocks in both cars and trucks as original equipment.
Realmongo...I think the E6SE blocks were used in 86 correct? I believe they had flat top pistons but I could be wrong. And I think those heads were only used for that one year...
Let's get back to the original question, I only want to know what Ford actually changed between the blocks to warrant a new casting number.
