I'm looking forward to seeing what direction you go and of course you will do what you want and everyone will think it's great in the end. However, it's half the fun debating the plan imo, I have learned a ton of info on this forum with ppl not agreeing with me.
Anyway, I think since you indicated an aluminum 427 bb, it's pretty logical to look at output, weight and cost factor comparisons with the 427 sb, 427 iron BB with a lightened car etc.
I really vascilated back and forth between several options before going with the 427 sb, like George did (and I agree about sb427 vs. bb427, with the modern head designs, the sb heads are darn good, particularly when you consider that you want the necessary flow with as high of velocity possible). I looked at the 502 ramjet seriously and frankly if I had seen the custom hood design that a guy built for his 502 ramjet, I probably would have gone that root as it would have been cheaper (but less power than my 427 sb). I also looked at the 509 Merlin and 595 hp (dynoed) Shafiroff 434 sb crate motors.
I think that a lot of guys are thinking 'bang for the buck' issues as most vette owners that mod their cars want to get the most power they can for their money and clearly you are going against the grain a bit. But like I said earlier, do what you want and everyone will think it's cool in the end anyway.
