Still struggling with white smoke fuel smell from exhaust

If that's a Chinese HEI knock off (and it looks like it is), check the timing with a light as it revs. We installed on on dad's 350 TBI Chevy and the timing was all over the place. Way too erratic and jumping. Thought the TBI was acting up but instead it was the stand alone dizzy which was junk.

To add to the above post, timing that jumps around will cause vacuum to do the same. For what it's worth, I have never liked the GM HEI unit...not in a small block Chevy and certainly not in a Ford. Give me a Ford duraspark or MSD any day.

Okay guys I have some updates for you. It snowed here pretty bad the past 2 days and its like 3 degrees out and my driveway is icedso I wasn't able to get the truck outside and started today, but I took some photos in my garage.

1. First of all I have a C4 Transmission not a C6. Some guy was helping me with my truck a while back swore it was a C6 so sure why not, but I looked at the pan today and it was 100% a C4 transmission pan. So I don't think that changes much, but I just wanted to let you know.

2. My oil is close to "black" after just 60 miles. I changed it about 2 months ago drove 60 miles and changed the spark plugs then too. 

3. I am using Autolite 25 Copper spark plugs (I bought the same ones that the vehicle originally had in them). I can't find my gapper tool, but once I do I'll post what they are gapped at.

4. My Valve modulator is a push green stripe and it was bone dry inside the tube coming out of it so I am going to assume its not siphoning any transmission oil.

5. All the photos of my rockers, carb, trans, oil, etc. Last two pics are of the gauges I just finished putting in and my first time using vinyl, I think it came out alright.

All in all, she looks pretty good to me but I'm no expert. Love the dash and good job on the vinyl. For spark plugs, I typically use the Autolite/Champion 45's and gap them at around .042-.045 when I swap in an electronic ignition setup.

Motor looks pretty clean inside for 100k...

'79 and up stamped rockers. Looks like it had the extra emission port transfer tube threaded holes in the ends by the PS pump mount. Definitely not stock era, possibly a 5.0 transplant. Hopefully you find some grey paint on the block. Smells like a junk yard transplant. I'd pull the intake and check out the gaskets since some of the plugs were oily.

Driveshaft yoke is dangerously short and not engaged in the tranny which is why it's leaking so much.
