Re: Thinner piston pins and moving pin up in the piston
Instead of reducing the pin diameter, moving the pin up in the piston is going to result in no loss of strength or gain of weight. Running the pin up into the oil ring groove has been done successfully for a number of years. With a raised pin, after the pin has been assembled into the piston, pin re...

Re: Valve stem off center.
Valve action is dynamic not static. When a valve seats in a running engine it does not place itself gently on the seat in a manner that with slight lateral load biases cause it to leak. It pretty much slaps shut and self centralizes with the assistance of springs and inertia. The forces at play in a...

Re: KB 350 119 domed piston volume.
Yes, crevice volume is included by some manufacturers, some give a pure dome volume which i see as the most common.
Just remember, when adjusting compression by machining the piston crown that each cc is around 2.7g, this saves a lot of wetting out.

Re: Metal clad valve seal removal
That works fine if you can get to the side of the seal. Not so good with cam on bucket.

Re: Metal clad valve seal removal
As Bent said, burn the shell with a map gas gun. This works on seals that have the sealing media continue under the metal shell. Heat just enough to collapse the lock on the guide, if you continue burning you can end up attaching some of the molten seal to the guide, this is a pig to remove especial...

Re: Old school ring seating trick ??
IN the early seventies where i worked we had a number of early Case W7 & W9 loaders, the operators would idle these things for ages as they thought the bosses were checking the hour meters to see if they had been on the job. Periodically these engines would start to use oil at an abnormal rate, ...

Re: Lightweight spring retainer
Dual effects for the S&S set, one, to reduce inertia, the other, as quoted to introduce lubrication to a triple wound interference spring set.

Re: Lightweight spring retainer
S&S provided this style for years without issue.
If the manufacturer has done a stress analysis that shows them to be sound with their intended use there should be no issue with them.

Re: Soft Valve Tips?
If the tips were faced were they done stroking cross ways or rotated on the facing stone? There is not typically a running condition that will make rotary skid marks. What is the peppering marks on the last retainer and collets? Not necessarily on the intakes. On heads with same seat spring loading ...

Re: Brake shoe fitment
Brake shoe flex is pedal travel.
Are you using a line lock?
Also, if the brakes barely hold or actually don't hold the car staging, what are they doing in the top end?
