641" C-head, 1170 hp

My rods are light for sure. I don't like the quality of the Groden rods and only have them because Mark McKeown sent them to me. They where not in Groden packaging, so they were probably old stuff he had laying around he wanted to get rid of. I am thinking about building my own rods when I find out exactly what material to use and if I can get it. Otherwise, I'll probably switch to GRP.

Very nice build David,I can't wait to meet you and see this Beast at the Bash

I am still hoping to bring it, although it will probably just sit there. I hope it will move under it's own power, though. I will have an air-conditioned trailer and a bunch of chairs for everybody to sit and talk hot-rod!

any updates David ?

Dyno tomorrow, Thursday July 14, 2011. Hope to get it on and break it in. I'll keep everyone informed. I will provide any and all info.

David with this Monster! Its gonna Rock!

Good luck David!!

Well????????????????????????????????????????

He is at the dyno working on getting it on and started.

Just got in. We are having some problems with the coupler plate and the pilot bearing. The dyno guy is going to take it off tomorrow and get it resolved.

David, what's it all going to weigh? Did rasbury give u any idea? Motor looks sweet! If u start building rods let me know... or call me.

Still haven't got this deal started yet. Maybe today it will happen. Don't know a weight yet Jerry. Probably in the 2400-2600 lb range with driver.

Fancy

nice hat!

Latest update is not a good one. The cam sensor deal is giving trouble and the computer will not sync up. The engineers for the MFI system are working on it today. This is a brand-new EFI system and they are still dealing with a few bugs here and there. This is a new problem they have never seen, so they are checking over very closely. We also had a fuel pump leak and that turned out to be the seal in the Enderle pump being in the wrong place. I chose to stay out of their way today and let the smart people iron out the problems. They are going to call when they get it running.

I wish you the best of luck David. I know what a setback these things are, but it will be well worth it in the end when it all comes together.
