SFfiredog: Ok. I understand. Thanks for the explanation.
PatBuckley: Who said my car was original? Wasn't me. REAL yes. Original no.
Southernfriedcj: I also didn't say the Aluminum engine wasn't a "correct" engine for the CSX. It clearly is. I think the alumium block is a really nice peice.
Its a choice between newer technology or staying with original equipment. Each has their pluses and minuses IMHO. I wanted to stay with original equipment wherever I could because I wanted my Cobra to be "as it was". And it is.
As far as strength and durability maybe the arruminum block is stronger. But I'll say it again. An engine that was chosen by Shelby for FIA competition and which powered the Cobra 427 to 5 SCCA A production titles is good enough for me and can offer more performance and power than 99% of us here can handle or use given a good servicable block, good parts and a good build.
I also know that I don't have to grind any stamping off my block and paint it to desguise it as a REAL 427SO because it is a 427SO. No explanations needed.
