My 1970 valiant 4 door

Its been awhile since i have posted on my build thread. well i got off the crutches and out of the walking boot from my reconstructive foot surgery in June. I have painted the engine bay and the engine. Received my rebuild stuff, cam shaft, and a very generous friend gave me a turbo, Mallory hyfire IV ignition and gave me deal on getting the crank polished and a valve job. Just got the pistons and rods put together and the cam bearings put in but the cam did not go in easily and created a lip on the front bearing :banghead: still not sure why it would not slide in easily? Now i need to get the hydraulic rocker arms, shaft, and push rods.
