    87 R10 TBI injectors will not spray

    Guys, one more thing to check when problems like this occur, is the small rubber hose between the fuel pump, and tank outlet tube. Over time, these will develop a hole, and is the worst thing to diagnose. It's one of those "outta site, outta mind" things that will leave you with a lot less than...

    Replace that injector with the EXACT size...do not go bigger.

    Has anyone ran 4" pipe one a 350?

    You will loose a crapload of low end torque. No bigger than 3" for single, dual 2.25 for duals on a stock-ish engine.

    350 starting without fuel pump relay.

    The fuel pump relay is only for the 2 second prime shot in these vehicles. If your oil pressure comes up quick enough, it will activate the pump. If oil pressure goes dangerously low, it will kill the power to the pump...unless the wiring has been dicked with.

    87 V10 5.7 Runnin rough

    This is especially true now, since the Vortech intake manifold does not have an exhaust crossover to heat up the air fuel mixture when it enters the manifold. Hot Rod, the vortec has a higher flow rate than the TBI heads, and more volume, wich throws everything outta whack with the stock TBI...

    87 V10 5.7 Runnin rough

    Nope, at this point, that stuff doesn't matter...the fact that he has vortec heads without the proper tune is the big ticket issue...probably didn't install EGR Anyway. Correct. Split hoses usually bring the pressure down to carb spec..8 and under

    87 V10 5.7 Runnin rough

    Foamy Nailed it! The tune is the problem most likely. I would recommend an adjustable regulator and 14psi. Contact Eldon at Wester's Garage in Canada, he may have a tune loaded and ready to go...at least I expect he would, as Vortec heads are a popular swap. The only alternative, which is labor...

    engine running funny

    Agreed Rich, I usually recommend a more stocking timing setting while troubleshooting...then when everything is at a good baseline, the Ping is the limit!

    engine running funny

    Ok, when you say you have the Holly 600 clone, is the float adjustable like a Holley? This should be correctable, and it sounds like the float may be too low. Holleys are the best aftermarket carb out there...and, I think the summit is made by Holley anyways. I like to use the clear sign plugs...

    engine running funny

    I haven't sorted through this thread, but have you confirmed that your balancer has not slipped, causing the timing to be set wrong?The only reason I ask, is because you said there was no black smoke to indicate a rich bog, but, if it was a Lean issue, there would be pinging, and possibly...

    350 TBI weird idle and deceleration issues

    Throw a new fuel filter on while you're at it.

    350 TBI weird idle and deceleration issues

    Ok, Cool. The ECM activates the light on any trouble code to report, however, you will only get it for a troubled sensor, OR IAC. you will not get codes for Fuel issues, like pressure, fuel pump, bad injector/spark misfire. Sensors do get lazy though, and until they meet a pre set threshold...

    350 TBI weird idle and deceleration issues

    If the check engine light does not illuminate when you turn the key to "on", the bulb is likely to be toast. I would start there, and also inspect the wiring/or any plugs on the Vehicle speed sensor, which is located in the tailhousing of the transfer case. Inspect the wiring at the IAC as well...

    what muffler do you use?

    Magnaflow, or any straight through types of full body muffler. Screw the Flowmaster gimmik ********. Stuff eventually rusts, and comes loose. Length will dtermin volume...the longer, the quieter.
