Alright new injectors on the way

Alright I just bought some injectors and they shipped this morning, so hopefully they will work.

I think mine are just too gunked up from sitting. I got one to free up and start clicking but then it got stuck open and wouldn't stop leaking fuel, so probably flooded that cylinder out now, I had to relieve pressure in the rails to get it to stop.

So now I will just put these new or newer ones on and see what happens

One more problem also before driving

Can't turn left


This is as far left as I can go:


Open to any and all opinions on how to make this work. I did run headers when I had the old SB 350 so there must be a way to make them work

Updates....Updates

Alright well I guess the vids I promised are on hold....

I pulled the headers off and am going to tow the car down to the exhaust shop to get the header work done right, so I guess you could say they are now going to turn into custom headers...

Congratulations on your swap, well done
Couple of things I see in your video that I will comment on though. The position of your filter means that the motor will be taking in air that has been through the radiator....read HOT. It has been proven that for each 10 degree drop in intake air temperature, power goes up 1 percent. Therefore, if you are taking in 200 degree air now and move the filter to the outside of the car to take in ambient air at say....100 degrees, you will have a 100 degree drop in temp and therefore should theoretically pick up 10 percent power due to the denser air (more oxygen in the available air). Of course this assumes a little more fuel to keep the air/fuel ratio where it needs to be. I don't know a lot about EFI systems, but I would think the computer would adjust for more fuel when it sees denser (cooler) air.

Other thing is, I would fashion a shroud for the fan.

Those are actually both in work. I'm still deciding on a good spot where I could put the filter and then I need to make shroud

I am in the process of doing the same swap into my '69 C10.

I was wondering if you knew how much the 5.3 weighed just itself without the tranny?

Thanks!!

Yes, but you won't be able to use one of the bellhousing holes.

You'll also need a flexplate spacer and matching (longer) bolts to mate with the older torque converter.

The spacer and bolts are available from GM for around $50.

The PCM can be tuned so you don't need a VSS input, however for the PCM to control the fuel map as best as possible for optimum MPG, its ideal to have a VSS hooked up to the trans.

Dakota Digital (among others) sells a pass-through VSS that will still allow the use of a mechanical speedo cable.

What happened to the 4L60e?
