throw a carb on there and be done with it IMO.. as for flywheel you wont find one from ford it has to be 28oz imbalance and 157 tooth. I searched for hours and check every parts store, the best and cheapest place i found was ebay, for about 100.00 buy it now it's a new billet steel unit with 28oz and 157 teeth, perfect machining and SFI 1.1 i believe, i wouldent hesitate to buy another. You'll also need headers for the 351w swap, i went with
BBK the fitment was great(i have lowered solid engine mounts so i had to make the dent bigger to clear the steering shaft), but now that the engine is out i'm going to have the headers ceramic coated locally. Also if you need a power steering pump mount PM me, i have a billet march setup for the 351w that i wont be using since i'm going with manual steering
