ok first off i have a jumpy idel bounces from 500 to 1000 RPM

second off stock injectors on a 1990 mustang 5.0 is 19 lbs and i am putting a 347 stroker in it i wanted to know is 19 lbs good or like 24's???

 

[qcrun98]

I believe the 19lb injectors would be way to small for that engine. You may want to get a bigger fuel pump and injectors.

 

[putnam88]

true

thats what i thought but then i have also heard that if u get ur comp reflashed then the 19's will work just fine and i know that putting like 40's on there would be over kill cause that would be like a graden hose of fuel and im not dragging it profesionaly so...

You need a bigger injector plain and simple.

NO ONE can tell you what injector you need w/o listing your combo.

 

[putnam88]

combo

i have the ssi intake and a 75 mm tb and i am putting it all on a 347 stroker with going to be 205 afr heads all forged 4340 piston rods and pistons

Make sure you throttle position sensor is working correctly to fix you idle, also you might want to go with some 30lb injectors for that 347 and a bigger fuel pump, at the very least 190lph, but i would suggest 255lph.

 

[Grn92LX]

Why a bbk intake? Definatly NOT what i'd use with 205's on a 347. What cam? What size exhaust? You need 1 3/4" and a 3" exhaust.

You need 36-42lb injectors and a 255 pump.

every thing u sead is right i havent decided on the cam yet but 32-40 wouldnt be over kill on the motor cause i hear two much just drowns ur motor and makes it run ****ty
