I am in the midst of building a new engine for FI. The sleeves have been bored by Dan Benson. I bought a race engine rotating parts from FXMD. A 3.2 replica of their race engine.
The parts have been balanced by a machinist. The main and conrod bearings were installed according to instructions. The clearance are within specifications. However, 5 of the 6 conrods do not have any lateral freeplay where it is connected to the crankshaft. The moment at least 2 of the conrods are tightened the cranshaft wont rotate.
We have checked the main and conrod bearings clearance and they are all within OEM and BC (aftermarket) recommended specifications.
I am at a lost on how to resolve this issue. Shall i get the machinest to machine of the side of the conrods to create a slight lateral freeplay with the crankshaft?
Any ideas, advice and suggestions are welcomed.
