I am guessing they are this part number?

Although they could just be normal 350 truck injectors. I ran a pair at up to 50 psi for thousands of miles. That was 20 psi base fuel pressure and a 4:1 rising rate regulator getting 7.5 psi of boost from under the Weiand 142. In about 1 year, I killed 3 well built 700r4s in about 20K with that setup.
