GT40 or Truck upper?
I have a 347 short block with ported polished performer heads, Cobra ported polished intake, BBK 1 3/4 long tube headers.
I would like to know if I should replace the Cobra upper with a GT40 or Explores truck intake. Please advise. Thanks Red Rider |

Why don't you just port the hell out of the cobra intake that you have? I'm not sure, but I heard that the cobra upper will flow more then the gt40 if you get it fully ported. That will save you money for more mods.

from whatI understand, the explorer is about the same as the Cobra, both of which flow more than the GT-40 which is a little more of a torque / mid-rpm range manifold. If you really want to do something with your Cobra, check into having it extrude-honed.

I thought that you could not put an Explorer upper with a Cobra lower...

I used the GT 40 upper intake and was not very impressed compared to the Cobra "Extrude Honed" intake. Comparing the two I did managed to get another 15hp out of it. I had them gasket match to a Felpro 1250 and had the Edelbrock heads ported to match. The GT40 is a nice looking intake, but you can't do much with it.
