50psi fuel pressure ok for stock injectors?
Hey guys, I'm putting a 355 in and reusing my TPI, I'm real pressed for cash and I'm wondering that until I get new injectors if it will be ok if I bump my fuel pressure up to 48-50psi on the stock 19# injectors? Thanks.

your stroking a 305? tell me how that works out.
you will need to change the computer chip out.
and you will need new injectors - those on your 305 dont put out enough gas.

You can get buy with the stock LB9 chip and running the 19lb injectors until you upgrade, although the engine will be running lean. Bumping up the fuel pressure is going to help some but is only a crutch really, your 355 is going to need at least a stock L98 chip and 22lb injectors. Ideal set up would be custom tuned chip and 24lb injectors.
