Engine popping into exhaust

[Tigger]

Hey guys, when I drove the cherokee, I just remembered that it backfires in the exhaust quite a bit, power was really lacking, and I am thinking the timing is off and the carb is WAY ot of adjustment from all the unburned exhaust smell coming into the cab area. So what is the proper timing for a 77 360?

[Tigger]

Oh and it starts like a champ, two taps of the pedal after sitting a week and it fires up. Oil pressure is good (by the factory gauge) and idles fine a bit high but its smooth.

I want to say the timing should be 8 or 10 btdc on the 360's. Are you sure there are no vaccum leaks or intake leaks?

you need to get that engine timed it is essential and you can really damage your motor

78 360
auto =6 to 10
manual = 3 to 7

Yeah I know that is on of the reasons I am not driving it right now. Thanks guys I will most likely work on that this weekend.

i have a problem similar to this but mine pops through the carb,
i recently changed the timing chain and since the it pops through the carb when going to full throttle from an idle and it has a bit of a miss.
the timing marks are correct. it has a new carb but didnt pop before the timing chain went.
the lifters wont pump up either so i didnt know if that would cause it so could someone please help me, steve

Double check the firing order and that the wires arent crossed, was rotor lined up with #1 cylinder @TDC when you replaced the timing chain?

man i have checked everything and i did everything the way it should have been done timing wise.
everything is where it is supposed to be, ive done everything but check for compression. ive pulled plug wires off while it runs ect. but i never checked for a vaccuum leak and im going to put a new cap on it.
the lifters like i said will not pump up so when i get it running, correct or not im going to go through the new camshaft break in procedure to see if the pump up and well see if not it is off to the junkyard to get me some heads

if you re-checked everything, check the compression, it is possible you have a bent push rod or bent valve, and not allowing it to open all the way, also causing the lifter noise.
