well it you basically want to get big enuff injectors so you dont have to run high FP..i would go with 36# injectors..at least 30#..i mean are you ganna try to get this thing in the high 10's or are you ganna just drive it on the street..cuz that combo will b capable of some sick time once its tuned..i would suggest a custom burnt chip after said and done..i would also go with a Pro-m 80mm mass air meter..
and as far as TB it depends how high your ganna rev it..i mean with the cam you have in it i would suggest a 70mm..but if you get a big cam go 75mm
then depending on the rod ratio of the 347 you built will determain how high you can rev it safley..
