SCOBRAC,

Thanks for your advice, so what you are saying is porting matching and good head work are the secret. From your post the
the middle performer manifold seems to be better suited to my application, as the bottom single plane is still to higher rev range, same as the shelby item. But I see the Edelbrock version fits under the bonnet, for what its worth!

Can someone downunder (NZ) buy heads that have that sort of work, because "all to often" in my build here I have been sent sh*t, and they have had to replace it. I think some outfits think we will send our seconds, he wont send it back, as it will cost to much in freight! Sorry about the gripe but its true.

Getting back to the KC engines an power, I would like to purchase an alloy block (std 427 size) and some good modified heads, and manifold, running between 10.1- 11.1 comp pending on how much avgas I want to use (hassle paying big $ and getting it) I want this engine to spin to 7000, but as you mentioned it would be silly to sacrifice mid range power for a bit extra up top! I should mention the car is being built for road racing, I originaly wanted to go SB but as the alloy blocks have come down in price ............!
