Hi all... This is my first post of probably hundreds.

I am relitively new to this, I just bought a 66 Nova 2dr hardtop tht needs restoring.

It came with a 327 with camel hump heads, flat top pistons and a Holley 750 carb. Owner claims 300-350 hp with this setup. We fired it up and it sounded rather smooth. The carb needs rebuilding.

What is the most logical (and cost effective) way of making 400 - 450 ponies with out heating up the block too much?

I'm sure there is many different ways of doing this, I would like to know the most popular route. TIA
