It falls on its face because of valve float. Replace the valve springs

First I’d check is your accelerator pump on your carb if you’re having issues when you hit the gas hard. Then timing. Then air fuel mix.

Probably not the first to tell you not all ‘78’s had square headlights…. But if I am, now you know. Also, M does not stand for modified. It’s just M. And also, also: these engines barely flow 350cfm without extensive head work, so “I wish it had a 4 barrel” would make it perform worse, not better. That’s why they all came with 2 barrels

Sure you have already fixed this by now but mine was the fuel filter on the carb. Doing the exact same thing as yours. I put a new fuel pump, new distributor rebuilt the carb put a electric lift pump to help the mechanical pump and it still would get warmed up and stall. Thought it was vapor locking so went through and put new fuel line in the engine bay all wrapped thermally and it still did it. Last thing I did was remove the metal fuel filter on the carb and haven't had an issue since.

sounds like you need to adjust your float it may be a low bowl causing you to stall out due to lack of fuel when you stomp on it the bowl empties out before it can fill up and or fuel pressure is too low caused by a weak fuel pump or worn accelerator pump diaphragm.

It could be something in the tank or in the fuel lines I had a truck run great if you were easy on it no trouble soon as you hammered it it would die everytime I ran new gas line from tank to carb and it fixed it the carb had a bunch of rusty stuff from the gas line literally Rustin apart from within

Get yourself a new HEI style distributor. All self contained and just a one 12V wire is needed. Check fuel pump pressure and float level.

Upgrade to GM HEI distributor. Use that wire to the starter as your input and then use the tach output on the distributor.

Tach green wire goes to positive side of coil. On mine I use the 12 volts from the cigar light for the red wire then ground wire I found good place under dash and green cable put thru fire wall to coil. I would definitely put that module back! He must have switched the distributer at some time to a points and condenser. Or other possibilty is he put the icm some where in the truck

Your exhaust could be to open. If you are running straight pipes try putting cones in your header/manifold. If you dont run straight pipe then it's the carburetor. Too much air and not enough fuel and it is choking itself out on the backstep

I had a problem with stalling for years, and I finally discover it was the magnetic pickup in the bottom of the distributor. It would only cause problems under load or acceleration. Cost like 10 bucks. However, since you may not have the normal distributor this may not be the problem. Another problem I had with mine for years was the brake booster would draw down engine RPM when pressing the brake hard. That turned out to be the check valve installed backwards on the vaccuum advance. I discovered that by looking at pics in a book!
@alanmeyers3957 Жыл бұрын

I bought a carb spacer and wrapped my fuel lines with some heat shield stuff. It pretty much fixed the hot start/hot idle problem. Luckily I've never had vapor lock completely but it's still annoying as fuck. I ended up removing the carb spacer though (it's called CoolCarb) don't buy it because mine started leaking and when I removed it the inside of it had started disentigrating. So now I'm back to square one, debating doing an electric pump. I'm gonna try some ethanol free gas too. Also I have a hard time believing the corvette story unless you blew past him and he didn't know he was racing.

Hey I didn't say you did , just curious because the truck seemed to be assembled with different component's like you said the front clip looks to be 76 , the steering column looks to be around 76 . 79 had the plastic that covered around it and the 79 had the wide chrome mouldings with the rubber insert on the cab and box .. but like you said they are great trucks , owned mine from brand new and had a few that I have drove for awhile and stripped them for parts . Your stalling could be a stuck float , the float is not returning to it's proper position and when you hammer on it drains the float bowl and then slowly refills so you can drive it normal .. just a thought

My 78 had a similar problem it was the fuel cap didn't have a vent, it was vapor locking. The truck wasn't overheating or anything, just when it was hot out it was building up the vapors but nowhere to go, now it runs and starts no matter how hot it is outside.
