Thanks for the invite Bruce but no way I can make it. I have a 13 year old german sheppard mix recently put on phenobarbital to counter seizures. Anyone who has been down that road knows the drill, they can't walk and need to be carried everywhere including outside in attempt to get them to go. He's too much dog for my wife so I'm housebound until he gets past it - 2 weeks is typical to regain balance and motor skills. You can believe it or not, call all it a lame excuse, but that's the deal. If the shelby spec motor was an iron block for the purposes you describe, then clearly not the higher tech entry for other purposes I thought it was, therefore I stand educated on that front. But I do not discount Bob Bondurant's experience and knowledge with racing cobras, on that point I believe what he has to say 100%, just can't ignore it. He has no stake in either motor [unlike here
] and can drive what ever he pleases. I would also venture to say his SBF-SPF was a means to an end and not the other way around. I don't doubt your BB revs well and would truly enjoy some passenger seat time in an original, sorry circumstances won't allow it.
Evan, your example was an aluminum 427 Shelby motor that "if lost" would be $30,000 to $35,000.00 to replace. My example is an aluminum dart SBF, so in fact apples to apples - but I concede my build was extravagant, from the race block up - all high end components. Price out a NASCAR motor and see where you end up.
As for the rest, oh never mind.
