if you get a 350 roller block, long block (heads/cam/engine) all you need is a 350 Memcal/Eprom (computer chip $70@ gm parts direct), and a 350 knock sensor, and 22lb/hr injectors. |

You don't really need the computer though if you can find one might as well get it. all you really need is 22lb/hr injectors and the knock sensor. everything else is cake, And it's an easy swap. but you will need stay with the same year or newer 350, well actually 87 or newer because the difference in the head to intake manifold bolt style. So stick with an 87-92 350 and you're good to go. |

They use 22lb/hr stock. Rated at 41ish psi. 24lb injectors are Frod injectors and are rated at 39.5ish psi. Thus when you add more pressure like factory tpi, they act even bigger.
Johnny, You need the 350 memcal. Period. You could run on 19lb/hr/305 bin like you did.... but it runs like crap and isn't good for it. You need to match tunes. |

Mine didn't run like crap, It just didn't run to full potential, So it's not NEEDED, if he can't find one and needs that engine in then he can run without it, hell he can even run the 19lb injectors as long as he gets an AFPR and bumps it up to about 60 psi, of course that will burn out the injectors and the pump faster but it can be done, I would RECOMMEND getting a 350 chip and 22lb/hr injectors but it's not absolutely impertive is all im saying |

Like I said though, 350 chip is $70 @ Gm Parts Direct. Forgot about having to supe the PSI up on the 19s yeah. Not a good idea either lol. |
