Mopar Cam 284/484 or 288/497

I agree, I was running the 292/508/108 cam with 11.3Scr I installed it straight up (108) cuz I thought I wanted the top end rush! Well bad idea.I got the rush alright, but The bottom was soggy. I advanced it 4 and it was still soggy.I advanced 4 more and it was still soggy. I put in 4.30s and the sogginess was bearable. I got rid of that cam.
I say "got rid of" like I was POed, and I was. That cam had a fantastic top end rush; from early 5000 to 7200 that thing was a beast! But being a streeter and with 3.55s there was not a lot of opportunity to exercise it, on account of 7200 was 64mph at the top of 1st gear. And the sogginess at the bottom, was there every single time I started from a stop. Yeah, me and that cam, were not the best of friends.I was glad I had a clutch.
I got rid of that cam,just as quick as I could.
Oh yeah,I almost forgot, moving that cam from 108 to 100 made almost no difference in the top end, on account of the tires couldn't keep up anyhow. In the beginning I was running 245s, cuz I had blown the budget on the engine :( A little later I got ahold of some slightly used 275/50s, which also couldn't keep up, so I put them on my 1980 Volare 225/904, which had no trouble at all NOT spinning them. Next I put 275/60s in there, the largest I could fit on the stock rear-end, and you guessed it, they were not up to the task either.
I got rid of that cam.
It made too much power,in a place rarely visited, and not enough low-end grunt which was continually visited.I got rid of that cam.
It did have a very generous midrange. But so too did every other cam I put in afterward. From the 270/280/110 to the current 276/286/110. Oh and don't let anyone tell you that these two cams are virtually the same, cuz they are worlds apart. I would never have gone away from the 270, except that it dropped lobes. The 276 is a whole nuther cam, and I often miss that 270. When this 276 dies, Ima going back. And then Ima going to do whatever it takes to make that little FormulaS 60ft waaaay dowwwn lowwwww.
