Ok so my 1979 350/350 c10 wont rev past 2k all of the sudden. The trans or tc went out on the way home from work one day and wouldn't rev without dying. I swapped the trans out and still wont rev up? I need help fast on this one. This is my daily driver and need it back on the road! Thankyou.

Did you also swap the torque convertor? Sounds like a timing issue otherwise,........ distributor possibly. Do you have an HEI?

Yes, I swapped the torque converter. Thanks for the fast reply I appreciate it. It does have an hei distributor, I checked all the spark plug wires last night and they were on good. I dont have a timing light, ill see if my uncle can check that for me sometime this week.

i think it has to do with the distributor... maybe the module... we´ll see what others might suggest..

The cap, rotor, module and coil are only about 7 months old. Could it be the distributor shaft? Because that is original..

naw i dont think it could be the shaft...could check the vacuum advance mechanism including the hose, and open up the distributor.. check the weights and the springs see if everything looks normal in there... by the way is your truck carb or tbi?

Ill check all the lines when I get off of work. Its got a rochester carb on it.

when you rev it, is it a slow rev; like it has to catch up to itself after you push in the gas peddle? what happens when it dies? just like flat out dies, sputters?

Yeah it's really slow and it sputters for a little then dies. Seems to idle just fine. Weird, motor is only 2 years old, same with carb and exhaust.

check your choke, i bet thats your problem

79brent · « **Reply #10 on:** May 08, 2013, 04:40:53 pm »

what do you think could be wrong with the electric choke? sticking maybe? I am gettng kinda tired of these rochester carbs. I want to get the holley 600.

Nothing wrong with the quadrajet, they are good carbs. I would check your weights and springs in the distributor as gildardo suggested. If it idles fine, but unable to advance sounds more like the situation. The weights have to move freely.

79brent · « **Reply #12 on:** May 08, 2013, 07:20:43 pm »

Alright sounds good guys. Thanks for the advice, ill check it out within the next hour and see if I can figure it out. Will keep you posted. Keep on truckin!

Ok I pulled the cap off and everything seems to be working fine with the distributor. I tried to get a jumpstart and realized that I kept losing juice instead of getting it. Crawled under the truck and the starter solenoid was missing a nut and bolt that connects it to the case? How does this happen and could it be causing my problem with not revving up? Regardless im gonna get it replaced, cheap autozone starter anyways, also gonna get the good battery cables to replace the autozone ones. Thoughts and comments?

gildardo01 · « **Reply #14 on:** May 09, 2013, 10:30:05 am »

well, if you checked the distributor and everything seemed ok we can scratch that off our list... did you check the vacuum lines... and the vacuum advance canister? if everything is ok with the ignition then we can check the fuel issues... when you rev it and it shuts off do you sell raw or overly rich mixture of gasoline? when the engine is warm does it still idle or does it also shut off... quadrajets are good carbs... have to keep them clean though... speaking of clean.. are your fuel filters clean.. including the little filter inside the carb...
