1973-1987 Chevrolet Pickup: Cylinder 1 backfire through intake

Wed, 05 May 2021 09:35:07 -0700

78 gm 350 5.7 Cid. 4 bolt main Backfire through intake/carberator.

Rods are good, even compression

New distributor, timing gears/chains, plugs, wires, fuel lines, fuel filter, new edlebrock 650cfm carb, lifter springs don't appear to have any wear (push test). When I disconnect cylinder 1 plug from distributor, I know longer have back fire.

My thoughts are a potential whiped cam lobe on cylinder 1 or a single bad lifter. Lookin for help!

Mon, 26 Apr 2021 19:00:50 -0700

engine turns over but after a few turns it locks and makes a terrible noise. Then it will turn over again but it seems as soon as I have ignition it locks again. Firing order is correct. All parts are installed correctly.

1973-1987 Chevrolet Pickup: Why is my window coming out of guides and binding?

Tue, 21 May 2019 06:12:19 -0700

My right front window will not stay in the front guide . the guide[vent window] seems to be too far to the outside but I don’t see any adjustment to bring it more in center. I thought maybe my regulator was bent causing the window to be too far to the inside but I tried a new gm regulator with the same result.

1973-1987 Chevrolet Pickup: Is the lock up torque converter needed on th350?

Mon, 25 Feb 2019 08:02:46 -0700

I have a 61’ Chevy c10 with a 78’ 350 5.7L. With what I think is a th350(might be a th350c) automatic Transmission. While changing the tranny oil filter I found a plug with all the wires cut and nothing connected next to the speedometer plug on the right side and later found out it is for the lock up torque converter switch. I haven’t driven the truck because I swapped engines when I got it. Does the plug need to be connected and hooked up to a switch for it to run well or is it something I don’t have to worry about and deal with later? Is the transmission a rh350 or a th350c if I do need the lock up? ( no computer in this truck)

I have an '87 Silverado that has just begun her long recovery. Among many minor issues, she shuts down when I am coming to a stop or slowing down.

1973-1987 Chevrolet Pickup: 350 4×4 rear seal went bad for a long time undetected

Mon, 19 Feb 2018 06:20:50 -0700

I h ave always been on top of checking the fluids and doing the proper maintinece on my truck and other vehicles. I was a lube tech for 5 years tell I decided I needed a change. But I had never heard of this one tell it happened to me.

My rear seal went out in a 4×4 turbo 350 and ended up mixing fluids between the transmission and transfer case and went undetected tell one day I lost all gears except reverse. Can any one explain this to me and is there any were to go for a ifixit style rebuild of a turbo 350. Never done it before but the way ifixit has helped me learn to rebuild phones i know I could do a 350 with a tear down and rebuild. Or is the 350 just shot. Please help I inherited this truck and it's all I have left that was both my grandparents.

1973-1987 Chevrolet Pickup: Automatic transmission downshifting problem

Sat, 16 Dec 2017 06:05:02 -0700

Shifts through the gears just fine, but when you let off the accelerator and it downshifts it makes a loud noise and the rear wheels tries to lockup. Sounds like gears grinding. Jacked up the back of the truck, and the axles spin free as can be. Only does it on downshifting.
