x2 on the cam. Mine was done before I got the truck. Its a mystery what it is but its a 360 thats been out completely hot tanked and repainted grey and put back in. Valve covers/pan/cover/intake are all blue. It only has 15" of vac at 650rpm at peak tune, with 20 deg. initial timing 38 all in by 2800. Its insane how much timing this engine likes, it hates anything under 18 base. I have vac adv connected to the carb. Not certain where they degreed the cam at either so it could be straight up or if used the stock AMC timing set it may be off by 4 deg. Either way zero yours out and install something with some good lift the stock units were pathetic and couldnt begin to fill the cylinders adequately. Mine does move quite well for a big truck. She can lay the speedo down >100+ at 1/2 throttle without even wheezing. I know the stock 140hp/285tq 360 wouldnt do that.
