    That's a different animal. The 60 degree is taller plus he has all the intakes stacked on and a ~1 1/2" adapter. No doubt it's sitting a solid 5" higher than it would on a 3800. I'm not saying it can't be done I just thought he might be looking for input on the build in progress. If he does go for a cowl induction hood it makes sense to draw in air from there as opposed to adding a couple feet of tubing.

    from looking at the first pics, i too was wondering about the TB.

    my first guess was that he was doing away with the BBV and was feeding air to the SC from the stock TB in the original upper/ now lower intake manifold. i edited his pics to show what i was thinking. maybe this idea can work? but it will be at the expense of the BBV.

    it would need a block off plate inside of the old upper intake manifold so that the TB would send the air to the old port for the BBV. then into the rotors then down into the old intake manifold to go to the runners so from the setup he has now the old upper intake and his adapter plate would both need modification now.


    i have seen some cars that cut holes in the fire wall and ran pipe thru it because of the lack of space. i think it was a fox body mustang running a crazy big turbo... and to make the pipe layout clean... they ran a 90* elbow off the carb into the fire wall .... wait it went to an intercooler in the trunk! was a Water to Air IC and it had a big ice tank for it.

    ever think of trying to move the engine mounts forward? or using a northstar TB or other TB that is shorter?
