ALSO, when the rev limitter is hit it only kills power by killing spark to cylinders or fuel but engine would just bounce off it and not lose a lot of RPM. Listen to race cars when they are staged and waiting for green light, you will hear them bounce off rev limitter

 

That's true, the TBI doesn't know what engine it's sitting on top of. But a 350 would know it has a 305 TBI sitting on it. There's a reason why the 350 and 305 TBI injector pods are different, their flow rate corresponds to the engine size. Although your engine may be running ok the way it is, it's very likely that it's running lean, especially if you have headers and/or a free-flowing exhaust. Is it too small to starve out the engine? No. But it's too small for best performance. And your last sentence is making a reference more to a carburetor, where fuel flow is directly affected by engine rpm's and cylinder vacuum draw. Fuel injection has it's limitations until they need to be stepped up in size according to fuel demands of the engine.

 

i dont think u copied it all, missed a IMG, lets see if this works. nope. well i wonder if your settings on the bucket account are locked for viewing or something like that.

 

i know if you go to photo bucket and search people with my s/n 1991camaro350 you can find and see all my pics and videos

let me know if you found them and i will put up more

 

You mean like this? http://s868.photobucket.com/home/1991camaro350

 

looks like your gage is showing double what the rpms really are, its idling at 1800 and sounds like about 900.

 

OK, this is a prime case where a little more shared info from you from the beginning would have been very helpful.
I watched both your videos. In the first one you said the speedometer is broke. In the tail of your trans there is (should be) a VSS (vehicle speed sensor). That's what is used in lieu of the older style gear drive for a cable driven speedo (yours is electric), in addition it sends a speed signal to your computer. If the VSS isn't hooked up, or if it's bad, not only will your speedo not work, but it will "F" up other things as well. If the computer doesn't know how fast the car is going (via the VSS), then it won't know how to manage things such as your air/fuel supply, etc. Get the speedo fixed, and I wouldn't be surprised if your cutting out problem goes away too.
In the second video, I can tell by the tune of the engine that it isn't anywhere near the rpm's the tach is showing. Mine was the exact same way, way high both at idle and while cruising. These 90-92 models are well known to develop misreading tachs, and that's what you have. Don't bother thinking you have a super low rear gear ratio, you don't.

 

Agree with Camaro69,should have said something about the speedo in the beginning

 

Do you have acheck engine light on?

 

sorry about not giving the right info i should of told you everything that i seen too really new to this bare with me please

it has came on and it was like i wasnt running on all 8 cyls,so i pulled over and shut it off and turned it back on and it was off ,but rarely comes on

I started at friendly chevrolet today and the bottom but some cool dudes there ,, they said they could help me get it right, but i would still wanna get others opinion on top of that "U guys know your stuff" so one of the guys took it on a test drive today and said my tach was reading dbl of what it should, but he said he would help me mess with it
