We received the model of the crank back from Crower, and Dale used it to check clearances and fitment on the girdle, bearings,  and rear main seal. This is with BBC main and rod bearings.

I know some of you guys prefer the old school way of 'just whittle it', but it sure is nice to know everything is perfect before whittling it!
38 when you say Crower sent you a model crank. Do you mean a cad model that can be installed in your Cad drawings. I so WOW!

That's correct. Like us, Crower does a SolidWorks model, before they whittle the crank. We were able to get Crower to send us the crank model, so that we could 'match' it with our girdle/main cap/ and rear main model.

Everything fits like it should, so now, both us and Crower can download the info to a CNC, and get parts coming! :-D
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

Richard, I don't know about fly, but I hope we can make a mighty fast one! :wink:


I'm going to run water tank, instead of a radiator Do I need a thermostat, or just run continual circulation?

I guess I'm thinking that as short of period of time the car will run, I may not benefit from a thermostat?

Thermostats are a good thing to raise internal operating pressures inside the eng. and heads. Also I run 25 # a racing cap on the radiator in a box.

Ditto on the thermostat, We used a hand valve to control the water flow to warm-up the engine on start-up the first year. Then went to a thermostat and it worked much better water lasted longer and didn't have to worry about some one leaving the valve in the closed position. :cry:

Thanks for the PM's and replies, everyone! :cheers:


Ok, here are some high-tech (lol!) mockups of the cooling tank, and the chiller tank.

This is the remote thermostat housing- (2) 12an inlets, and a 16an outlet.

Buddy,
I a not sure that I completely understand your water system. I looks like you are going to have two water tanks and I think that you plan to have a radiator of some sort in one of them, what is the other one for?

Rex, I think that's the tank for the charge cooler for the supercharger.  Nice build Buddy!!!  Tony

Man, I told the guys we should keep it simple! I was afraid the use of all the high-tech gadgets and stuff would be confusing! Lol! :wink:

The 'tank' in the nose is the engine cooling tank. The 'tank' in the driving compartment, is as Tony said, the cooling tank for the supercharger.

Ok, we're going to have to kick it in high gear to get finished in time.

This may be a little late since you've already started on the girdle AND the dimensions of the inside of the block may not accomodate this idea. But since you're having the crank made from a billet, have you thought about adding additional main bearings ? kinda like the guys at Uncommon engineering did on the Hudson "9X" about 2/3rds -3/4ths the way down the page at http://www.uncommonengineering.com/  .  Might allow you to make more Hp & still keep it together.

It's a little late in the game for that, now!

I think we'll be ok. Bob Brooks is building one, that he's planning on running Nito in. He feels he can safely get 6000-6500 rpms, with the stock crank.

I think it's safe to say, that Bob is far more qualified to make that assement than I am!

I've been reading the 'Treits Streamliner' thread. What an awesome build!

Reading the oil pan post, I realize that I've completely overlooked getting one built.

Any suggestions for where to get a custom, one-off, dry sump pan built?

You might try Jeff Johnstone @ Billet Fabrication.
He'll probally need a block to do it but so will most others.

Then again the guys you currently have doing work seem up to the task too.
