So, a 296º-.557" is really 288º @ .020"/256º @ .050"
That sounds pretty good. The 557 in my street 440 I measured 288º @ .020", 257º @ .050", 165º @ .200 "

Good cam, I made a little over 450 hp with a 9 1/2 to 1 340 with ported J heads. I went as fast as 11.34 at 117 in a 3150 lb Dart with 8 inch convertor, 904 and 4.56 gears.

An alternative is the 284/528 with 1.6 rockers. I'm super tickled with mine.
I liked this cam too in my 340, it pulled hard as hell, idled almost smooth and very responsive, i replaced it with the .557 296 mopar cam and i took it right back out it didnt pull as good as the 284.

I ran the 284-.528" w/1.6 in my 340 for 5 passes.
11.84:1, iron heads, 4600 stall 9 1/2" Dynamic, 727, 5.38 x 32"
11.65 @ 118.4 MPH (1.73 60 ft. )
I brought it home, tore it down and changed practically everything in it.
MP could have done all us SB guys a favor and stuck with 106º LSA.
Like the scoop?

Which is why, as we discussed, Im going from the .557 to the Comp 20-633-5.
Dur @ .050 260/266 .558/.555 w/ 1.5 Rockers 106 LSA
We'll see how it works.

I have this cam in my 68' 340 yellow dart and have yet to race it at the track, But it runs great on the street so far. My combo is made up of old left over parts from other peoples projects that never got finished and I bought, and I did not want to get rid off the stuff years later, and so I am building this 68 dart 340 just for fun. I am using this cam with matched springs, etc the original X heads,& 340 block, .030 trw forged 12 1/2 to 1's, 727 with 4200 stall, hooker headers,& full flowmaster 40's exhaust with factory exhaust tips, 8 3/4 rear with 3.91. Holley strip dominator intake and 780 holley vac.sec.... This is a car of mine that will sit parked more than it is driven as I have the blower car and my GSS's to play with too. I am curious what the dart will do, but plan to race it as soon as we can at orlando speedworld ( my closest track) I have used the 557 profile in my big block 440 demon 340 car also for awhile before switching to a roller cammed blown race motor and went a best of 11.30 et with the 557 cam and 11:1 comp ratio. I attatched a pic, hope it comes thru... Grant Eaton 407-947-9005
