What would you do?

Yeah the cam will be coming from Dwayne Porter. Though I know all about the losing of hp through manifolds, it may be too much to ask throwing the 273 manifolds on. What about making a set of log manifolds, something you would expect on a turbo set-up? I have done it on a turbo 4cylinder, pretty easy to do really. I'm sure someone makes the flanges....

Dwayne's definately up on making power with manifolds and his cams flat out work (not to mention his valve jobs/head work). But - you can use the later A manifolds and that would be my 2nd choice... Just get the best you can get (68-71 340 monifolds) because one way or another you will be pumping through them, not getting any help from them. I don't think making longs is wortht eh effort when a factory set will work.
