tight engine
Ive assembled my 351cleavor using all my best effort, however i seem to have an ongoing battle to find the reason for an extrememly tight engine!
I double checked the bearings actually tripple checked for the proper bearing clearance.
I have checked and found that the cam retainer plate bolts could have been causing a drag on the aft side of the cam gear. Fixed but problem persists.
checked the valve settings to see if there is any valve to piston contact! found none.
looked at the cam lobes and dont see any problems!
what am i missing? the engine is so hard to turn over by hand i have to use a small breaker bar to turn it.
Ps: I have not fired the engine yet and wont try till this is resolved.
Any help is appreciated! |
