engine jerking hard at100mph then stalling out? i have just put a ls1 in my 68 camaro and i have had it for about a 100 miles now and i was playing around today and went wot from first to third and at 100mph the car jerked violently three or four times, my foot was still on the gas and it wouldnt accelarate at all. i let off the gas and hit the gas again and it back fired really loud three times and stalled out. i stopped and checked some things out and everything looked fime, but i am no mechanic to say the least. it cranked right back up. i drove it home. it drove fine almost all the way home. i was riding at about 2000rpm's when it jerked violently again and then acouple secods later it stalled out. when it jerked at sounded like my exhaust was going to fall off. now it is not really wanting to start. it will turn over and maybe run for a couple seconds and then stall out, once again the exhaust sounds like it is about to fall off. i have a full tank of gas, and the voltage is good. do any of yall have any ideas?

What rear gears are you running? Sounds like you hit the speed limiter. With 4:56's or something tall at 100 the PCM will think you are going maybe 150. I think the fuel cuts out at 130 or something. Doesn't explain the mishap at 2000 rpm, but the first issue may have caused the second. Just something to think about.
