Hi all, I'm hoping someone can help me with a question I have. I have a '94 with a 305. I'm getting ready to do a cam upgrade and installing some 081 heads. I know I'll need to get a tune to make it run right. But I'm wondering about injectors. I ended up with a box of various injectors. Some of them are labeled 45, 55 and 65. Which I assume is the PPH flow rate. from looking up the part numbers it looks like the 45 are 4.3l and the others all reference back to 350s. From what I've read I think the 305's are supposed to be around 50pph. So my question is should I try and run the 55pph ones since the engine will be slightly modded. Or should I run the 45pph ones and just crank up the pressure to make them push closer to 50ppm. I'm just not sure if putting in the 55's is going to make it run too rich. I know I could try and reuse my old ones but I'd rather use some that have already been cleaned and tested.
Thanks for any advice you might have.
