af2 is there any room to cut down the neck a littlte bit? i can fit 3 inches directly above the carb, but where the louvers are, there becomes a low spot which is why i need less then 3 inches. but i should have about 3 inches directly under the carb so i would jsut have to line it up right. ill get that only if there is any room to cut atleasy a quarter of an inch off.

No there is not . The inlet is 3.5" and cutting the neck 1" would be like hanging you're self with 1/2" to spare. The neck is rolled to go into the carb very well and I myself wouldn't mess with it at that point Confused

That is a nice looking setup AF2. BTW, I took a long look at your build the other night. Nice work. I like the choices that you have made so far.

Tim.. Didn't you say you are running a carb spacer? Can you delete it and run the hat instead? It might also be possible to machine the top of the intake to make it 1/4" or so shorter. I run a slightly shortened Vic Jr. on my Nova and if it had any adverse effect on performance, it hasn't shown on my timeslips. I think it is more important to have a good entry angle into the carb than the extra height underneath. If your homemade setup doesn't pan out, that is a fine one that AF2 linked. And the price is right too.

Good luck

dont have a spacer, just doubled up on carb gaskets to cool it down a little. if i could cut atleast a quarter inch off the one af2 posted, then i should be alright with that. plus its 26 bucks so you cant go wrong.

Tim, Looking at it You could gain 1/2" if you cut 1/4" and roll 1/4" of the opening that is left. The aluminum is dead soft and does not take well welding with a Tig. The aluminum forms very good though. BTW thanks Art.
