Re: roe crank pin kit
I have both the Paxton and Roe pin kits installed. Initially the Paxton alone. I calculated the added rotational resistance with the Paxton kit (this is 3 years ago so it is all based on memory). I think it was somewhere around 25% increase. That was with 1/8" solid pins. The Roe is larger diameter roll pins. The difference is not all that great, but the Roe does have higher overall strength.
As to the expansion issue it is not a factor. A steel pin in a steel crankshaft will have the exact same rate of expansion.
The most important aspect is to drill the hole straight and not at an angle as AB did. His issue was installation related. If it is not straight removal of the damper will be damn difficult, if not impossible.
