93 5.0 upper intake questions
I would like to put gt40x ford racing heads and a cobra upper intake with a 70mm tb. Is this possible? I'd like to put in a e303 cam too. What else would I need to make this possible

yes but the cobra intake only has a 65mm opening where the TB gets bolted to it, so if you want to use a 70mm TB then port the intake to that size. Other wise the 70mm TB is pointless if it flows into a smaller opening. I hope that was clear enough.
As for the E303 came.....BAD CHOICE All the A,B,C,D-----Z303 cams ( no good ) It is out dated and there are better cams out there....That cam was made back in the early 90s, cam teck has come along way in 20 years

Ryanw is right about the throttle body. It won't flow any better than a 65 in your case but you can always upgrade your intake later..
As for cam, e cam is alright but I gurantee you'll be happier with a TFS1 cam. Good power and perform well all around.. But you can always step up to comp cams...

the Cobra/GT40 and Explorer upper intakes have TB opsnings that are 70mm. Some are a tad (1mm) less, but all I have measured are larger than 65mm.
