    Decent progress made today. i put in the steering rack and front bracing, along with the fan, oil pan, etc.
    one thing i ran in to was the crank pulley was not aligning very well with the water pump or the alt. it was about 1/8+ inches in. ended up pulling it back off and getting some 1-3/8" x 14 ga shims from Tractor Supply. i cut a notch for the key in the shim and put the pulley back on. Lines up quite well now. guess i never noticed it before.

    tomorrow i will do some odds and ends and then prime the oil pump. still waiting on the rocker assembly but i want to have as much done as possible when it arrives.

        Well pictures always make things look better. but it is certainly better than it was before.... well all except for one thing. for those who look closely, they will see i have the cross-brace in upside down. realized it when i went to put the radiator in.
        always something.... and i even had pictures to reference. ha!

            Back from my trip to some warmer weather. unfortunately my rocker assembly showed up the day after i left. So start up had been postponed....

            put the assembly in this morning while getting the heater in the garage up to a comfortable temp. went thru my check list, twice, than connected the battery, opened the garage door, got the fire extinguisher ready, climbed in the car and turned the key... nothing. well a few clicks and nothing. i had charged the battery this morning while putting in the assembly and all looked good. So i am now figuring i got something hooked up wrong or i have a loose connection. went thru and checked things... all looked good. So i tried again... again a few clicks and nothing. Lights looked ok, all else seemed fine. So i pulled the battery and went to NAPA. girl put it on the tester and she said the tester said i needed a new battery. i said... that's what my car said also...

            So got a new battery, came back put it in, went thru all my check list again... and turned the key. Took a few cranks but it fired up. ran the car for 20+ minutes at 2000 rpm with little variance here and there. Car ran ok but i had this intermittent miss. nothing regular but it kept up the whole time... not sure what it was but today was about breaking in the cam so i did not mess with anything. after i shut it down i did notice my front carb still had the choke on some. it did not fully release. could be the issue. anyway worked on that and a small leak from one hose. i did not start the car again. i wanted to let it sit and cool completely. So i will start again tomorrow.

            i plan to recheck the valves again before starting. then check the timing with a light and with a vac gauge. after that i will balance the carbs again and check to see how rich they may be running.

            If not for the miss, i would say it was a great success. No strange noises, no big puddles on the floor and nothing caught fire.

            one question i have is when to change out the breakin oil. i have read where some change it after the 20 minute run. some leave it in for 500 miles and some change the filter after 20 minutes but leave the breakin oil in for 500 miles. curious as to what you all do here.

              pretty much finished up today with this project. i started the car and warmed it up. checked the timing which was not close by the gun anyway. So i set it to 12* BTDC by the light. that seemed to take care of the miss or popping i was getting. also checked the timing with the vac gauge. most vac i got was 19" and when i set the timing back to 18" it was again at 12* BTDC. So feel pretty good about that.
              balanced the carbs and tried to set the fuel mixture. balance was good but not so sure i got the right mixture. anyway, hopefully project done and car ready to try out. i am anxious to feel the difference that new valves, springs, cam, cam chain, rebuilt diz, and a shaved head will make. just need to get a decent day to try it out.

                a before picture. getting rid of the EGR and re routing some hoses cleaned up the area a bit.

                      Your battery hold down bar is upside down. If you reverse it, the top edge will not be so close to the terminals. It may have some letters ingraved in it, mine does and they will be upside down, but trust me, it should go that way.

                        Congratulations, huge milestone! Did you go with Richards GP2 cam? It may have been the thread but I missed it.

                          your hold down and mine are different. got mine thru Moss but i am not thinking it is the right one. my other side is wider than the one i have on top. i sprayed the angle with plasti-coat paint so it would not conduct and also put that piece of velcro on top. i should probably try and cut the other side off and flip it over.

                          i went back with a stock 76 cam. probably the best mix for the driving i will do.

                            DD - Thank you for all the great documentation. I am about to do much of the same on my '76. Hope you can answer a few questions.

                            How does it run? Is there a noticeable increase in performance? (I also have a re-done distrib from Ron that has been sitting around for a year and will eliminate air pump and EGR.)

                            How much did you shave off the head?

                            I hope to install main and big end bearings today and maybe the new timing chain and sprockets but need to make a decision about pulling the head soon. Unfortunately, I never good good compression readings before pulling tranny and many other parts so I don't really know the condition of mine yet. A good boost in performance would be a compelling reason to just pull it and get it up to spec and shaved.

                              it is hard to say how much of the change is due to the head shaved, the valve job, the rebuilt diz, the replaced cam, 4* advanced valve timing ... so many changes. i had the head shaved to what was the depth for 9:1. can't exactly remember the amount. but it was just over .100 i believe.

                              the car runs fine. i am not sure i notice all that much change in the low end. something i expected to notice. but i can honestly say it is a different car over 3000 rpm. something i did not really expect. i am guessing having the vacuum advance now is the reason for that.

                              don't get me wrong, the car runs better at all levels but just not really a big noticeable thing at the lower rpm.

                              Now, i have not played with it since figuring out my rotor button was wrong. the weather has been cold and i have been south for a while so really have not driven the car a lot. i want to run as is until the weather gets warm and i see how it runs then. thinking maybe at that point i will tweak the timing a little and see how the plugs look for carb adjustments.

                              My car only had about 79k miles on it. i did replace all the rod bearings and the bottom of the mains. have always had good oil pressure and the car ran pretty well before. i would not have even pulled it apart but i felt i had a head gasket leaking. figured i wanted to get to it before it got worse. then i fell in to that WIIT issue. (while i'm in there)

                              if you have any questions you think i could help with, feel free to email me.
