    Here is some information on rod weight for people that are curious. Comparison between LY Mopar rod with ARP bolts vs Scat H beam with ARP 2000 bolts.

      Next week I pick up my block from machine shop and rotation assembly from static and dynamic balancing.
      Everything else is ready to go.

      Can’t wait to go forward.

        Balancer is TCI rattler that I got used for cheap. I disassembled it, cleaned, run the case on lathe and put it back together. Want to keep it like this.

        it was in rough shape.

          OK so I started checking the heads. They were NEW SR heads from Indy, ported but never run, new heads basically. I was shocked how bad they were.
          To put it short, I had to re do all seats and ream the guides as they were too tight. Seven valves you could see light thru when closed, the seats were egg shaped. Seat height was also all over the place. Took a lot of work to have them sorted.

          Now I'm starting to understand all the complaints about Indy quality I saw online.
          Cost me a lot of money to have them fixed, planned to get vacuum pump but this problem fully consumed my budget for extras.

          These were much worse than any Edelbrock pair I saw so far, but Edelbrocks still were not ready to put on engine out of the box. Is there such a thing as head that you bolt on just like that? Very disappointing.

          Hopefully the new owners will get the manufacturing part on the right course. Any Indy head I bought needed everything corrected. The last set I got off of the 526 Indy Maxx that had Dyno time on them were completely gone over b4 being bolted on They needed lots too. Seems u can’t buy as y ready to run head s as Nd just bolt them on. Kim

          Well just realized I had to get more parts and another 2 weeks delay due to shipping...
          Have a look how fantastic locks and retainers I had on my Indy heads.
          They all are all over the place, zero consistency. This is just sad!

            All new...
            Frankly I'm glad I didn't need to add weight. I was worried about that.
            Financially this project is killing me. Whatever I touch seems to need replacing. I expected problems with Indy heads but what I discovered was beyond expectations. They needed valve job, fine but these locks and retainers killed me... Why bother using 10 degree set of such quality. Hope dyno chart will make me feel satisied.

            With so bad valve job dropped seat or valve is just a matter of time.

              Just a question regarding oil ring gaps. I got total seal rings and manual says minimum of .015” o mater the application. Seems small to me, any suggestions? These are total seal rings...

              The oil ring doesn’t see as much heat as the top ring does so it doesn’t need all that much gap.

              As long as they have a gap over the minimum send it.

              Don't confuse Total Seal brand with gapless type rings.
              Go to their websites and check what the manufacture says, not what someone who never used them says.

              It’s the OIL ring. It’s not rocket surgery.

                  Almost ready to start, had big problems with passenger side header. TTI claims It fits but its a joke...

                    In 1971 a friend of my dads was building a hemi for a roadster he hand fabbed in his shop. It was a beautiful car. He decided the shop had too much going on, so he bought bunk beds and put his two boys in one bedroom and built the engine in the other bedroom.

                    It all went well until they tried to roll it out the door! Had he figured out how to get it out that door, there was two more he had to get through to get out of the house.

                    So he cut the widow out and put a sliding glass door in there, added a deck and called it good.

                    His wife was a very unhappy person.

                    I made sure it gets thru the door before I started putting it together... The only problem was getting it down 2 stairs. We had to make it with me and buddy of mine with engine stand attached to it. It took us 6 hours with driving and multiple crane reassembly. It was good fun, not planning to do it again any time soon ;-)

                    My wife accepted all this mess quite easily, I'm still surprised about that.
