I will be rebuilding an extra 258 sometime early next year and I was wondering about the stock oil pump of which I have never had a problem.

Question:
On a stock 258 application would a high volume pump hinder or help the motor?

Seems to me in a stock configuration the high volume would not work to well w/no real motor work done but hence the question to the ones who know better.

I don't know.

Also, MC, do you make any for the 258, unlike the chinese stuff off the shelf?

Thanks,
Jim
