if i had money i'd get a roller valvtrain and new heads and be done with it.

ANY IDEAS, no matter how farfetched are appreciated.

collapsed lifter is nothing like saying "ditch that cam and get a roller setup. Where did that come from? Sounds like a timing or ignition issue to me. I've never see a carb blow back(flames through intake) unless someone sprayed lots of carb cleaner down it or the ignition timing was off badly. I have seen it happen on a perfectly fine motor but that was an alcohol race motor not a stock 350 with mild camshaft. Are you certain you timed the cam properly? Could easily be opening the intake valve when your ignition is firing or something.
 
here's the thing, i did fire it up one time and had it running fine for 30 seconds until i have to cut it off due to the noise and being inside. then later it fired up and revved to about 4k and cut off, has not started since. so maybe i bent some pushrods or some valves, i guess the valve covers come off tomorrow.

no no, i just want a roller setup. /forums/images/graemlins/grin.gif
 
Try reseting your valves it almost sounds like you have the valves set to tight. If you set the valves when they where dry chances are they are to tight causing the valves not to open and close or letting them stay open together cauasing the backfire.

Just a thought.
 
Update- we have compression (125psi, isn't that 9.5:1? seeing as 8.5x14.7=125, then add one to 8.5 because 1:1=0psi)
we have spark, we have valve lift, no bent valves, no bent pushrods, we have oil pressure. i guess its time for an air/fuel test and timing. so it's timing or fuel delivery.

I could be wrong... but I still think its timing related.

with the amount of carbs you've tried I'd start looking at timing. Pick the carb you feel is best, or freshen one up, or have one freshened up then start on timing. Go back to ground zero man. Reinstall the distributor to rule out being 180* out and go from there. Still have trouble well it may be time to pull that balancer and check cam timing.
 
I pulled the distributor this weekend and reinstalled it. While I have the valve cover off i'm gonna take the 1 cylinder till both valves closed (compression) and then take the balancer and take it by hand to 0. then set the rotor to #1 (all that's obvious i know, just going through it in my head and typing) then going to try to start the beast again. i redid half the valve today, and tomorrow i'm gonna redo the other half. There's no way to install the distributor backwards is there? i think i had it at near 0 last time. i'm also gonna blast ever jet, every inlet and every port of that carb with carb cleaner. but i want to buy a performer anyway, so i might just scrounge some money together and do that.
 
Either your valve timing is incorrect or your spark timing is, or both.

Keep turning the motor over, maybe you can eventually wipe all the assembly lube off your new cam so it can wipe as soon as the engine runs. /forums/images/graemlins/rolleyes.gif

I've never had an engine that wouldn't start immediately after assembly unless something wasn't done correctly.
 
Just because you see fuel in your filter does not mean that your fuel pump is working. You need to pressure check it to confirm. It's fuel related.

Wanna bet Tim? /forums/images/graemlins/tongue.gif /forums/images/graemlins/peace.gif

Sure. You can gravity feed a carb and an engine will still start. I'm still betting on spark or valve timing.
 
ok.

well tomorrow i bet it will fire- i'm doing an ignition day. nothing but ignition. if still no worky, we know it is the carburetor
 
Sound good! When you find out your fuel pressure and the required fuel pressure for your carb; let me know. /forums/images/graemlins/peace.gif

Have you done any mods to your fuel tank, pickup tubing, fuel lines etc.? Is it possible that you may have bent your fuel line somewhere from your tank to your engine? /forums/images/graemlins/dunno.gif
 
alright, it's back to the "poof poof poof poof" like 3 or 4 cylinders are firing. so i was given a carb today, so i'll put it one just to see what happens, and idk after that. . . this is getting ridiculous!
