Just asking, but why handicap yourself with 55 less cubic inches for the sake of turning high rpm that take forever to get to?

My 225 motors turn more than enough. Shift light is at 6300, high side rev limiter is at 6800. It will hit it.

Will be interesting to hear what happened.
Oil pump gear maybe?

Done blowed up real good......

Possibly, But I would hope not as it was a stock pump gear with a Stock Cam Core with an OCG Regrind on it.

We will find out.

It would be more of a fun experiment for myself more than anything.
I also happen to have 2 170 Short blocks now. I have never Driven a 170 Car ever.

I am not worry about getting to the revs as this Head and Cam combination work fantastic together.

Yes I am aware of the 55 CI Penalty and that is pretty big, however a lot of the vintage British cars did wonderful things with less than 3.7L.

This is not a Drag racing car for me.. I have one of those and it's ~242 Ci.

Happy New Year.

Last year was full of ups and Downs for Grüne Hölle;
April - July:
The good: Lots of Driving and Towing, a Track Day at CMP, A trip To Missouri and Back in 4 days with Daughter and trailer, and A trip to Carlisle.

Mid July - October:
The Bad:
I had the Fingers on the Pressure Plate Break, making the car undriveable... got that sorted out and fixed, then the engine went south. Hopefully this will be a better year!


Starting off with selecting a Block to build:
Here is the Core Block, Greasy, Nasty, Full 'o Sludge, Fresh from my collection of things slant 6 - It had already been broken down in the attic, and I Boxed up the cam and sent it of to Oregon Cam Grinding To get a replica of the cam that is in the car now.




Cleaned and Ready for some prep work.
Let the degreasing, cam bearing removal, drilling, tapping, and grinding begin:



'Till Next time!

Making a bit more progress before it goes to the Machine Shop:




Broke out all of the porting tools..

Block prep is completed with the tools and abilities I have available to me. Its now off to the machine shop for the final deck truing, boring etc.

Every time I build an engine, I invest a bit more in tools... This time a Scale that reads to 0.1g and a Connecting rod Balancing fixture.


Got all of the reciprocating and rotating weights matched to within 1g, and will be sending that information along with the Crankshaft to the Machine shop soon to be balanced.

Greg,
Did you find much of a variance from rod to rod?

Well yes and no.
I had 8 rods that I had molasses soaked last winter.
They came out very clean as the molasses tends to slowly digest and degrease them too.
I had 6 that were between 758 and 762g. The 2 outliers were something like 749 and 765g.
From there I began the R and R weights. You can see my notes in the pictures.. click on them / zoom in and see for yourself.
I can never remember all those numbers that's why I write them down.

I got all pistons/rings/pins within 1g as well as the big ends and small ends within 1g.
Those final weights are not on my sheet but are on the final weights for the machinist to use to calculate the bob weights for the crankshaft.


Greg

There are no bob weights necessary for the slant six (or any inline six that I know of). Machinist doesn't even need the piston/rod assy, or the weights. He just will balance the crank with the damper, flex plate/converter, and or flywheel/clutch.
But, yes, you are correct about matching the weights of the other parts to each other. Did you include the rings and rod bearings in balancing? Being real "picky", they should be part of the balance.

Good To know Charrlie.

I dropped off some pieces at the Machine shop...
- Block
- Crank
- Honing Plate

The Machinist still wanted me to provide the weights of the Bearing Shells, as they are arriving this week. Still learning about all of this stuff. You say he does not need that info, but he was glad to have it.
I did not have the correct Size rod bearings on Hand.. Had The .010" and the 0.20" and the 0.30" but Not the ones I needed, so I told him I would call with those shell weights this week. I provided the Piston/Pin/Ring Weights as well as the Rod Recip/Rod Rotating Weights. They should have it ready in maybe a month or so (fingers Crossed)

I almost always give them the bearing sets and ring sets so they can do/measure what they need. I might worry if the shop says they need to find a bobwt for an inline 6, since any good engine machinist should know this is absolutely not needed for an inline 6.
