what kind of characteristic differences do the d1sc and f1 or f1a have in terms of boost response on a 346/347 motor. can you run a f1/f1a on stock block, like a d1sc on low boost and then turn it up later when the fuel and motor can handle it?

If you had a cam with a lot of overlap and some great flowing heads, you might get the boost down to where these larger head units will work. I don't off hand know of anyone who has tried it though. Bob

Does the F1 reqire a different intake hat, bracket, etc. How exactly would it be setup? I liked that elbow that you guys had on your site instead of the ATI hat. Is that available?

We can indeed make you the inlet hat combination that we made for the white T/A. Thanks for inquiring. Bob
