Do I absolutely need bigger injectors??
I will start putting my engine back together next week and I went way over budget putting my new 331 together. I have a 70mm t-body, ported 6037 edelbrocks and typhoon intake (ported lower), and 1 5/8 shortys. Can I get away with using my stock injectors for this coming season with a 255lph fuel pump and a adjustable regulator. I don't have any money left for a new mass air meter and 24 injectors. Should I risk running my engine lean or can I run this way until I save up for the injectors and meter (probably used to save $$$). I need a solution because my visa is on the verge of melting from over use.

Re: Do I absolutely need bigger injectors??
If you really don't have the cash then it CAN be done. Just turn the fuel pressure up.
But really for about another $200 bucks you can get a meter and injectors if you scrouge around ebay and the classifeds here and on other mustang boards.

You will have to run about 65-70 psi on the stockers. Set the fuel pressure and then go make a 1/4 mile run and pull the plugs and see how they look.

Re: Do I absolutely need bigger injectors??
what's the point in putting all that money into the rest of the combo and then skimping on the fuel side?
put 30's in it, and don't look back

Re: Do I absolutely need bigger injectors??
well like they said you can make it but i advise not to go to a track untill you get injectors and a meter. Likely to blow the motor.

You're going to burn the engine down with 19lb/hr injectors on a 331 stroker with HCI. Especially with old injectors that have over 100k on them.
