when i get this engine it is already set up for carb so i will probobly just leave it carb and ditch the tbi for a while. then do the ultimate tbi mods to it and them possibly put it back on. will i still need everything but the injectors? |

thanks a lot shifty |
leave it carb and ditch the tbi for a while The engine isn't "set up for carb", especially; at most, it just has a carb intake on it. Rather, the car is set up for TBI. That's ALOT of stuff. To set it up for carb, you'd have to buy a carb, buy a distributor, bypass the fuel pump relay control system and buy a regulator or remove the TBI pump from the tank and install a mechanical pump for a carb, and do something about the torque converter lockup. Far far more work and expense and opportunity for malfunctions than slapping an adapter on a 4-barrel intake and putting the TBI back like it was except with 350 injectors, and re-programming it. In short: swapping to carb is NOT the cheaper easier way to go. |
if the engine is not set up for carb then how come it comes complete. its crate motor ready to drop in. |
Don't do carb if you intend to do TBI someday. Just get the basic 350 HO and put TBI on it right now. |
you see im still not sure if i am every goign to go back to tbi. i mibght just run carb for a year until i get a stealth ram or mini ram or something along that line. so far i will need a new knock sensor, new fuel pump, fix the converter lock up and then what else? |
Because there's nothing there to "set up" for carb. It's "set up" for TBI to exactly the same extent it's "set up" for a carb. If it comes with a 4-barrel intake, all you have to do to completely "set it up for TBI", is put a $30 adapter on top of it. If you don't want to use an adapter, then buy a $200 TBI/Vortec intake. It's still only about 1/3 the cost of a carb swap, and a tiny tiny fraction of the trouble. No hacking, no rewiring, no dropping the gas tank, no hacking.... did I mention, you don't have to hack your car? That makes it kind of attractive, don't you think? I suggest, if you don't know what you're going to do with the car and whatever you do you might change later, do as little as possible to it now. Put the TBI back on it. Hacking it up to switch it to carb, only to switch it again later, is a waste of money and effort. And did I mention, you don't have to hack your car, if you put it back like it was? Drive in, drive out, done. Get your MiniRam later, and save up the money you would have spent on a carb, toward that. |
