340 HP's vs headers

LOL... I didn't realize this thread was old. I was answering the original OP's question.
Its all good, i forgot it was someone elses thread lol. I will still be doing the bit to the 318, but now will put it in my sons car when we build that project. An LD4B is a pricey vintage piece now, an i see em with a bunch of corrosion in the water jacket areas, so hows a Weiand stealth stack up against it? I kinda like squarebore manifolds myself, i think the eddy performer is a spreadbore.
