Cool, it shouldn't be too bad to change. About two months ago I went to the junkyard and took an intake off of an explorer, it is sitting in my garage waiting for when I can refresh the motor and put some new heads on it, lol.
So are we planning on lunch being noon then? It will take 47 minutes to get from Mac's Diner (if we are still meeting there) to Watkins Glen according to Google. We could stop at the Belhurst Castle too like you mentioned and spend some time there long enough to get to the Glen by 3:30...
The TFS heads that come with that setup may be too small for the 347... You can get a bare block from Summit for 700 that already has all the machine work done for the 347 internals to go in. You would just have to check around on how much it would be to get your block ready for the stroker kit...
