You'd better learn the chords:

Oh! Carol
 I am but a fool
 Darling, I love you
 Though you treat me cruel
 

Neil Sedaka pining for Carol King.   She was dating Gerry Goffin @ that point, and later married Gerry.

Neil didn't get any respect!

Why should the midget treat the K any better than he treated the "Grenade"?

Would that be the infamous DCB?


We have a winner.
Midget... I kinda like K1K.... maybe the engine will have a little kick....

We have TWO WINNERS! 

K1K it is - I'll get to work on the graphics.

Hadn't thought of that one - Sedaka is one of the greats, but when I hear the song "Carol", I think Chuck Berry or Keith Richards -



Keith openly admits he stole every lick Chuck ever wrote.

midget,

What is the chance of a trial fit up of the head/barrel(s)/block/ladders/studs/etc, sometime soon?

I'm looking to check the clearance of the o/size valves to the edge of the bore size of the barrels.

I'll do a partial assembly tonight and have it ready to check when the head arrives on Wednesday.

I'd like to avoid putting all of the liners in place, if I can help it.  Seeing as you've set up one chamber for the proposed valves, which cylinder(s) will we be checking?

I'll charge up the borescope.

midget,

Here are a few photos I shot at T & T last week.    The bore of the flow bench slider is 76mm, the biggest I thought would ever be utilized.    Proposed bore of current design 75.5mm, so roughly .010" less radially.   At 75mm, the reduction would be ~ .020" radially.


Uncut stock seats


Oversize valves fitted


Close-up of fitted oversize valves


It is probably OK because of the valve angle, but, it is close.   Given this bore size and valve centerline spacing, K1K is maxed out.

A shot of the head and valve opening rig, on the flow bench.


One more view from a different angle.


There is a bit of variation in the chamber to bore clearance from cylinder to cylinder.   It might be how I made the slider adaptor, or it might be some variation in the head casting(s).

That's the reason to check it.   If the bore appears to be centered more precisely on the block/barrel, I going to cross it off the list of things to be concerned about.

 cheers

I'll be by tomorrow AM with the block, etc.

Won't be working on it tonight, though.  Kate's birthday takes precedent.

midget,

Dimensions of stock BMC 1275 wrist pin:

Inside     ~.510"
Outside     .8125"
Length       ~2.50"

And they are hard enough.    Seems like the perfect spacer for the new torque plate.   Might have to grind the ends flat and square . . . . . . . .

 cheers

MM ventured out below the "cheddar curtain" today, taking a rare day off with the intention of checking out the clearance between the valve edges of the over size valves and the edge of the 75mm bore cylinder.

Things checked out OK, there is a bit of "casting misalignment", what you would expect from a cast part.  Checking was done on cylinders #1 and #4.   It is a tight squeeze, 5 pounds of parts in 3 pounds of space, similar to late model 4 valve bike engines.    Valve area is not as great as on a bike engine, but given the valve spacing and bore diameter limitations, the valve sizes being evaluated are "maxed out" for the combination.      MM shot some inspection cam video, perhaps he will post it up to the diary.

The larger diameter valves give the benefit of allowing some valve throat and valve pocket machining and matching, correcting some fairly serious misalignment in that area of the cylinder head.    The flow increases have been quite good for the amount of effort expended in these areas.

Some time was spent in the "Dungeon Laboratory" crunching some of the flow test data, and as soon as the test notes have been edited, I'll be posting a "Data Dump".    I'm working on a more comprehensive simulation in EA Pro, once that is done, an additional "dump" is planned.

There was a side trip to the shop of the Mini Maven to return some borrowed bits from the "Grenade".    Luncheon was at the local pub.
