First off,, dont go any bigger then a 19lb injector,,, if your not porting the heads or intake you can even keep the 14lb injectors, but 19's are your best bet.. You dont need 30's and would be overkill and possibly cause your worse gase mileage/performance over the 19's..
OK so you have no IMRC's which means the engine will have NOOOO torque down low,, even with your 3.55's your gonna be disapointed,, throw a larger cam in the mix and your gonna cry foul.
I've driven em all because I've done it all in my 96' Ive had a 3.8L with a cam 207/215 with no IMRC's talk about a complete and utter dog... yes the car would pull hard up top once it got too 4500 to 6000K but I would still be sittin at the light getting smoked by other cars... these TBIRDS are heavy!! you need torque. do not take suggestions from most of these mustang guys,, there cars are lighter and most of em run manual transmissions,, there a whole different beast.
The cam that came stock in your 97??? is a better cam then even the splitport engines have and its designed for bottom end torque. I've ran all three 96' Cam, 99 Splitport 3.8L cam and 4.2L Splitport Cam,, with the 96' being the best of em all.
based on your setup or plans you shouldve run IMRC's.. its like getting 2 motors in 1 with them closed it gives a very nice torque curve down low and with em open it pulls like a mofo.
? is why dont you like the stock cam?? was it based on what the old engine did or something else?
Lastly,,, we have timing chains not timing belts and they dont sell gear drives for are cars. the tming chains are great and there no need to change the designed other then a new chain.
IMRC Lower with a MSD window switch to actvate
SCT 2 (to change the timing and fuel a bit)
3.73's should be a minmum,, but 3.55's are good but keep that stock cam!
