Does anybody know where i can get the upgraded mopar lifters and rocker arms a 420a, because everywhere i'm looking its either out of stock or discontinued.

I'm not sure which ones you're referring to. But the common upgrade is 2.4 lifters and 2.7 rocker arms. Because the 2.4 lifters have larger holes for better lubrication and the 2.7 rocker arms grip the valve stems better. I bought all of mine from RockAuto, all are OEM Mopar parts.

Looks like Mopar has discontinued the 2.7 rocker arms unfortunately. Seems like every week I find something else we use that has been discontinued and it hurts. BUT, you can still use the 2.4 rocker arms as an upgrade compared to the 420a rocker arms.

It was a very limited production engine, the most popular would have been the Dodge Intrepid.

Summit still lists a lot of unavailable Neon Mopar goodies, assume that Summit will cancel the order if nobody else can get them either.

I snagged a set of rockers from the junkyard. Sebrings were the easiest to find at the time but that was a few years ago. Below are the vechicles that you can find 2.7's in with those rocker arms.

The 2.4 rockers as @BLACK'98DSM mentioned are a good upgrade over the 420a factory rockers. The difference between the 2.4 and 2.7 rockers is just that the oil squirt hole is at a better angle to hit the cam lobe. Physically they are not any stronger than the 2.4 rockers. I wouldn't spend much time or money trying to find the 2.7's over the 2.4's. It's not like people have issues with the lobes wearing out on 420a cams except for people who try running cheap Chinese aftermarket ones.
