slant six rebuild parts source??
I got main and rod bearings on eBay (since I wanted some odd .001 undersize mains that are not made anymore) but were on eBay, the timing chain from NAPA, and the cam bearings and pistons and rings through my local machine shop from EngineTech parts. For the /6, the EngineTech pistons and rings are made by Hastings. You can get the Felpro gasket sets in a lot of places.
(I get nothing from Jegs and Summit for /6 stuff; the MSD .8 ohm cold ballast resistor is close to the OEM part so might be the 1 useful part from them!)
