February Dyno Testing Session
We have finished up our testing for 2025, shutting the engine off on 12/20 for the last time this year. I am working on the write up, but I'm not that far yet. I am posting this note out looking for help.
Our next session will be sometime in February, although the dates are not firm yet. But the next session is really aggressive and will probably be 2 weeks in length. I really need some help for the next session. At this point I'm willing to get someone a plane ticket to come and help out. I don't expect anyone to come out for the entire two weeks, but at least a week would be nice. You really only need basic engine building skills to be able to help out, and of course to follow directions. The only possible conflict I have in February is 2/19 I have a doctor appointment here in FL, but I'm willing to move that if necessary. Let me give you an idea of what we are going to be doing. Probably pretty close to this order;
Ron will have both sets of Batten heads ready to test, I'll detail how difficult this was in the next write up. We will test both sets of Batten heads. The combinations are limited for this testing as we have to use a certain intake manifold and headers. The differences between the two sets of heads are limited, but as follows; One set had titanium valves, the other set has stainless valves. One set has smaller combustion chambers than the other. One set does flow slightly better than the other on the flow bench. One set uses studs and guide plates while the other will use a Jesel set up.
Once we are done with the Batten head testing we will remove the engine from the cell, disassemble it and clean it up. We will then install the high compression pistons and put a set of Batten heads back on the engine for a back-to-back on compression ratio. The engine will then come out again and get the original pistons installed back in. Here will install a set of Batten heads but with a smaller camshaft to how this performs.
Once all of this is done, we will install the A heads and stock engine configuration. We will run this combo to see how it compares the C, E, F and J head testing. We will then run the air gap manifold and dual port manifold on the engine in a stock configuration. We will run headers on this combo and a smaller camshaft for comparison in the future.
After this testing is done we will the run the stock Gen3 heads that Lloyd purchased, after they are vacuum tested and valves and seats cut. Depending on the initial results we will probably re-run all the stock Gen3 testing that we did. Dave will also have a set of Speedmasters with a medium porting job on them and we will run this with a few combinations. These heads currently flow 290 CFM at 0.600"
If we actually get to this point in 2 weeks or less, we will then go out and celebrate a job well done.
If you are interested in helping out, please reach out to me. As a warning the days are long. I like to be at Livernois by 6:30am, which means leaving the house by 5:40ish am. We do leave the building for lunch and typically finish up working between 5:00 and 6:00pm and then head back, have dinner, sleep, repeat. Even Dale is welcome to come and help.

Just as info one of the sets of Batten heads will be sold when all of this is over, or close to it. It will be the set with the titanium valves. I'll offer them with either a small block Edelbrock Victor intake or a cast big block Batten head intake, that I have showed pictures of before. It will also include the headers and maybe a set of the Jesel valve train parts (since I have two sets). Not sure on price yet, but it won't be cheap or a giveaway by any means. But I want to get them on the engine and see how they do first.
