Hot Rods XO/PP Bonneville project

Made the shifter handle today. Also finished wireing up the underhood and preped and installed the carbs

 

Sorry for the duplicate photos

 

The shifter looks good John. I was going to make it but you beat me to it.

 

I started another Flathead build today to sell for funding for the Bonniville truck. New .080 3 ring pistons, mercury 4" crank .010 R .010 mains new valve components, valves guides, Isky valve springs, Reconditioned rods, mercury heads, stock camshaft, stock intake milled deck and heads, .040 head to piston clearance. This engine will be ran and broken in
Ready to go sale price
$5000. Out the door.
More photos as the machine work gets done

 

Finally got the new engine fired up today.
Sealed up right away runs clean and is very responsive trying to get a video linked to this post

 

A little break in time and its off to the Dyno

 

Glad you’re getting back on track, so to speak, I hope the new engine does the job.

Its basically the same engine with some minor changes
1 bigger bore
2 better ring package
3 new cylinder head
With better port work
Smaller combustion chambers, giving higher compression
4 shorter header will change power band RPM
And yes this will require dyno tuning to sort things out. But I think this combination will be a better one over-all...

 

Here's a little video:

 

"one small step for man... one giant leap for mankind!"
It sounds great! Congratulations on this step, and good luck on the dyno tuning.

 

Thanks Dave...

 

Another great work day today. Final prep for the dyno next week.
We are almost ready for speed week 2021

 

Take us to the dyno shop with you!

 

We had a great work day today on the 640 XO/PP Virginia HAMB Special. I finished up the clutch pedal stop and return spring and bent and routed tubing for the fire suppression system, @Scott_Rod rod worked on the O2 sensor wiring and a leak in the oil pressure gauge while @john mullen buttoned up some under hood wiring. Then we put a fresh coat of Rustoleum in the bed. After all that we wanted to test the clutch actuation for the first time and I’m happy to report that the truck moves forward and in reverse on its own power! Now we’re ready for the dyno next Saturday. Here’s a little video from today.

 

We will have video's of the dyno testing so standby next Saturday afternoon

 

New OX gauge working

 

The kestral..
A complete weather station made just for the racer

 

Dyno test posponed due to rain this weekend. We want hot and dry weather for the test

 

Ran the engine more today purposely letting it get up to 200 deg before i put the fan on. Its really loosining up and i readjusted the timing, tweeked the carb some more and adjusted the valves. Man this baby is responding well above my expectations.

 

Bummer, John. We're on the edge of our seats waiting for numbers here!

 

John will get the numbers when they cross the finish line.

 

Sorry guys i know how everyone is on board with this and i promise it will be done as soon as weather is better. I want the best conditions so we can find all the power this engine will make.
The better the tune hear will relate to other places we may run such as Bonneville or Arkansas standing mile.
Hang in there with us..

 

The real dyno is white with limited traction at times and possible corrected elevation of 7 to 10,000 feet above sea level; not to be compared to pavement at sea level.
The running on an engine, axle , or wheel dyno is just a tool. A very valuable one but a tool none the less. Waiting to hear also....

 

I saw a post today from f book pertaining to the salt condition for this years speed week.
So far there hasn't been much rain over the winter through late spring leaving the salt much like it was in 2020. The salt is very dry and hard. No better and no worse than it was last year at
speed week
A little late for rain to melt the salt and smooth it out.
60 days before I leave for Wendover and the salt.
Comming fast..

 

Got to love that salt fever, good luck on your journey.

 

Changed out the oil today ready for the dyno I'm adding lots of ZDDP for the dyno pulls then change it again before Bonneville

 

I'm in need of a chevy 400 inch block needs to be able to bore to .030 over no more. Desperate
Pm me if you have one for sale John

 

Expand your Search to include a Dart SHP block. You will be better off in the long run. They are available starting with a 4” or 4.125” bore but are both the same.

 

This engine is for a restoration project and customer wants an OEM block. But I appreciate the info
