My intake and exhaust manifolds are limiting factors... I don't want them choking the extra cubes. I'm also building a clone and starting with nothing... I could build a 440 if I wanted too, but I want the smaller displacement faster revving engine.
I hoping to fit the car with the one of the new Passon 5-speeds, with a 4.10 Sure Grip out back.
I'm also not opposed to aluminum heads vs. ported stock. I'm looking at "gasp" Stealth heads (I'm fully aware of their issues with valve locks) for no other reason other than that they appear fairly stock on the outside.
If you have no reservations about using aluminum heads then I strongly suggest you do. You'll get more power, more reliability for about the same amount of money(after you have a set of 906's ported and reworked with quality parts).
