Crank prep work source
Hey all,
Getting back to building a couple new 3.2 short stroke engines for next season. Need the collective wisdom on where to send the cranks for prep. I used to use Armondo at CCR, but I hear that he's gone from the scene. I do have a fairly local shop that has done excellent work in the past, but they are not versed in Porsche info. I've given them specs and they have done great with that. I am specifically asking the engine pro's out there if the 3.0 crank should be cross drilled at #5 or? These are high rev pure race engines so any input on crank work that should be done is appreciated. |

I would definitely crossdrill #4 and as an option knifedge the counterweight. Top it off with a nice polish and a re-balance. We offer these services at Supertec if you are interested.

Dave @ Marine Crankshaft
http://www.marinecrankshaftinc.com I was referred to him by Henry @ Supertec. They cross-drilled my crank and rehardened it as well. Pricing was less than half that quoted by CCR.

Altho Marine is doable for me, does anyone have a reputable lead on the east coast?
