 and here are the center mains mocked up in the block, for comparison, without the girdle.
With sufficient thrust, pigs fly just fine. However, this is not necessarily a good idea. It is hard to be sure where they are going to land, and it could be dangerous sitting under them as they fly overhead. -- RFC 1925

Thanks guys- we're doing what we can!

On another note, Russ Meeks, Finish Line Coatings, has the valves coated, and is shipping them to Don. Bearings are headed to Russ to be coated, and the new head chambers will follow.

PIstons were coated last year, and still look great!

I really think these coatings help our cause!

Hi 38'

Not up on flat cads, what bolts to those bolt bose's at the bottom of the barrel.

New caps looking very nice!!

Since they are alum do you have more bearing chrush to make up for more expansion then they get hot?

Me and my buddy put a MT alum rod under hot running water one time and it grew 2 thou!!

Don, even though the mains appear to be aluminum in they pics, they are really billet steel. The bolts are 9/16, and there will also be alignment dowels on both the top and bottom of the mains, as will as in the block and girdle.

Your "running water" isn't as hot as mine, since you only raised the rod temperature approximately 74 degrees F (assuming rod big end of 2.250"). Practically every wrought aluminum alloy (from 2014 of ancient M/T rods to latest proprietary alloys of BME, GRP, etc. rods) has a temperature coefficient of 1.2 x 10^(-5)inches/inch/degree F. +/- ~5%.

fordboy,
What a delight to read your posts, I learn new things from every one of them. Keep them coming!! I agree with your thinking that the initial dyno runs show more potential hp above the max tested rpm as the testing does not appear to have found the actual peak horse power of this engine.

FordBoy, Dale should be sending you the info you requested! Thank you for all the info! I'm very curious to see what the mechanical/theoretical says is possible.

Chris, thanks for helping get that info posted!

I've just returned home, from a very good trip:

I caught up with Dale, Amy, and crew chief Mark. We had a nice dinner (translates into big drunk), and then made plans to go to Ross Racing Engines. The next morning, we dropped the crank off, for a .010 grind and nitrade on the rod journals, and a polish on the mains. We also dropped off the rods, to be checked for straightness and stretch.

I then headed over to robfrey's, to see the NACA 66 Special- what a classy build! Rob, thanks again for the hospitality!

Don is finishing up the main caps and girdle, and later this week the block will head to Boyd Enterprises, for a line bore and a valve job.

Tomorrow, I'm heading out to see Randy and John K.


We're getting closer!

38, Just spent all weekend reading this thread! And I must say, WOW!! Love the car, absolutely love that mill! The entire build is a thing of beauty and the fact that it's fast makes it even cooler! Hope to see ya on the salt in August! Keep up the good work!

Thanks Lsrjunkie-see you on the salt! :cheers:

More progress, this time on the rear diff and tranny dry sump! The motor is a 1/2HP, 12V motor, and the pump is a Weaver 4 stage. Both the tranny and diff will recieve 2 stages- 1 sump and 1 pressure.

Yea, I know it's a different approach-that's OK! :-D

From Don:

Buddy needed a pump for the rearend oil,, so he supplied me with a 12 motor and a pump and here is what I did. The mounting plate is machined out of 6061 alum. to bolt to the c face on the motor

Why such a powerful motor? [1/2 HP means close to 40 amps @ 12v]. Is it due to a requirement to route oil under pressure directly into bearings?
