Re: 1955 12 Valve NAPCO Clone
Has anybody left the rubber cover off the side plate? What is this for? Any experiences? Also anybody have a picture of the cam to injection pump timing mark pictures for stock timing and advanced?

Re: 1955 12 Valve NAPCO Clone
hey luther when u bled your clutch was there a bleeder in the lower cylinder ? I dont seem to have any kind of bleeder anywhere in my system. I want to shorten up the hose for my application and will have to bleed it in the neer future.

Re: 1955 12 Valve NAPCO Clone
Mine didn't have a bleeder but there is a plug in it. I just bled it by pulling the slave cylinder and manually pressing it by hand about 10 times. I had my line disconnected from the clutch master too.

Re: 1955 12 Valve NAPCO Clone
I think he means the marks on the pump and cam gear.
- NOTE: Stock/OEM injection pump timing has the "O" of the camshaft gear line up with the "E" of the injection pump gear. Here, you can see the pump is advanced by two teeth.

Re: 1955 12 Valve NAPCO Clone
Yeah that's it! I only did mine one over to line up the 0 with the C. The rubber over I was talking about is the one that bolts over the tappet cover. I think it is for noise reduction. I ditched it cause it was all broken.

Re: 1955 12 Valve NAPCO Clone
Here are some pictures from the long weekend. I managed to get the engine ready to drop in minus swapping the oil pan with help from my friends. I also got the wheel barrow welded in for my new firewall.
Here is the timing advanced one tooth. I fully retarded the pump all the way to the point where I could still get a closed end 13mm on and off the very back pump nut. You can see in the last picture where I left the rubber/plastic cover off the tappet cover. I hope this doesn't bite me in the butt but it was terrible shape. Anybody else removed this? Here's the wheel barrow firewall install.

Re: 1955 12 Valve NAPCO Clone
Here is the interior shot of the firewall. Not too big. I don't have a picture but I also cut my brake pedal and shifted the pad about an inch to the left.

Re: 1955 12 Valve NAPCO Clone
Nice work! The fire wall looks sweet man! Yes, that rubber cover is just for noise reduction. The only thing you will notice is a little ticking noise with that removed. Other than that, it's just an oil absorbtion pad.

Re: 1955 12 Valve NAPCO Clone
Thanks! It turned out pretty good I thought. I almost put filler on it and made it super smooth looking but figured this truck is too rough.
I got another couple of timing questions. Why would anyone bump there timing 2 notches? I would like to keep mine fully retarded where I can get to stuff but I realize I will prolly have to move it. Also is there any way to time these with a degree wheel or something to figure out what the timing is? What is stock timing? 1/8" bump? 1 tooth? 2 teeth? I know it depends on pump location and how it is clocked. I am just trying to figure out if how to time it. I heard of someone putting a timing light on one? How would that work?

Re: 1955 12 Valve NAPCO Clone
Thanks! I can't take the credit for the idea. My Dad came up with it. I just ran with it. You should've have seen the look I got at Lowe's when I tried to buy just the "barrow"!

We got the engine in last night. The firewall has a bunch of spare room. I prolly could have made it about 1 or 2" shallower. Its ok though. If I ever wanna move the engine back more I could probably run a mechanical fan . But this won't be happening for a long time though. I almost got it cranked last night but I didn't have any spare diesel and the mechanical pumps on a first gens stink. I hope it fires off and runs perfect. Heres to crossed fingers.

Re: 1955 12 Valve NAPCO Clone
Its nice to see that eng in there . You were kicken butt before your "set back" . Ive been sidetracked on mine lately. Were going to FL for a week in March. Had to do full brakes on my 05 3500. As well as ball joints , front u joints and rebuild the front driveshaft. That broke my budget. Not too bad tho. It would have had to be done in April anyway for commercial saftey.
Anyone know of any cool car guy things to do in FL ? Staying in Kisseme . I will need a daddy day out for sure !!!

Re: 1955 12 Valve NAPCO Clone
Y'all have fun down there! That's a long drive from Canada isn't it?! I hear on your budget killer. I just bought new tires for my 92 Chevy and I had to redo the front end also. Luckily my parts are warranted. Does that Dana 60 go through ball joints often?

Re: 1955 12 Valve NAPCO Clone
Good news! I got it cranked again but it seems super retarded. I am thinking about skipping the second tooth so I can keep the pump in the fully retarded position for easier tuning. What are y'all's thoughts? Who all is running two teeth advanced and what pump positions?

Re: 1955 12 Valve NAPCO Clone
I forgot about them swapping to the AAM. Is it a pretty big ring gear and no more CAD? I'm not gonna lie I had to look up KM to miles to see what that was for me! In engineering school we used SI which was much easier to work with.
Here are some pictures last night when I cranked it.

Re: 1955 12 Valve NAPCO Clone
Man the pump looks so easy to work on like that. I wish I could move mine. All that good cdn road salt made the lines look like twisting the pump like that would lead to a real leak. Bummer . I wonder if anyone has a affordable complete line kit ?

Re: 1955 12 Valve NAPCO Clone
Good news two days in a row. I'm getting suspicious. I was right about the timing being retarded. I pulled the injection lines off tonight and timed it the proper way with the dial indicator. I didn't have the fancy dial indicator that actually threads in to the injection pump so I had to rig something up with my magnetic base. Pump lift at TDC is supposed to be 1.25 mm or 0.049". When I checked mine it was 0.030" so it was off a good bit. I loosened the pump and advanced it until I got it to 0.050" or 1.27 mm and called it good. Threw it all back together and re bled it. It's running good now. I am gonna mark this for reference and do an 1/8" bump here soon. Also gonna mess with the full power screw. I need to get a new fuel pin and governor spring while I'm at it. I'm ready to burn rubber!
