Guys,
What is you're opinion about the stock 311B rods? I have a set and maybe want to use them on a 1776 or 1915cc engine (DPR crank, W120, 40dells etc.) What kind of RPM would they stand and what upgrades should be done or can I do myself? Is it worth putting money in them or should I buy a set of Uni-tech HD rods from CB Pefromance?
Thanks!
Jesse

O thanks Jordy  . So they are good. But what should be done to them and is upgrading the bolts a must? I also heard something about polishing the rods. What is polished and what does it do? |

Sorry for hijacking the thread, but what can be said about the stock Porsche 912 rods?

No offense taken Jim, by all means. IŽd rather have someone tell me the truth about them, so I can make plans swapping them for better items the next time I open the case.
They are of course weight adjusted and checked by a machine shop, but I do not have the details of what has been done to them.

Dave Mason has run the same set of stock rods for the last 18 years or so at 310hp and 9200 RPM trouble free. On a welded crank, to boot.

Sorry to get a bit off topic here, but are there any options for Porsche journal/length rods out there besides Carrillo? Something stout enough to handle maybe 140hp, 6500rpm max???
