Forgot to mention, converter in my 300 was a Turbo Action unit... I don't remember the part number, but it was a 3000-3500 stall iirc.
Trans was all stock except for the converter, and a T/A mild shift kit.

That's awesome! You're Duster went mid 11's with that combo! Was it a street car also?

Never ran the 509 cam, though I did run the old Street Hemi grind in my 64 300, 750 carb, 4.10 gears and a stick car too. I miss that car, many a 454SS and Iroc Z got spanked with it.

How much did your '64 300 weigh? I always got a kick out of people's reactions
when they got spanked by a big C body!

No idea, I forget those details, it was the late 80's.

I like the idea of a hotrod 300, looking at an SRT8 300. If I could easily swap in a stick I might get it.

I've always installed the 509/292 108 LSA cam 4 degrees advanced. 104° ICL. That cam works great in my opinion, even though it's an old cam that everyone likes to crap on. Some of the old stuff still has it's place.

I had a 10:1 440 w/ stock 906 heads, just a 3 angle valve job, 509/292 cam, Performer rpm intake, 830 holley, headers, 3500 stall, 3.91 gear, in a 3700 lb cuda. Ran 11.80s at 112 mph on pump gas. Drove it everywhere.
Switched to some home ported 915s and it ran 11.40s at 117 mph.

No street car but should have. .030 over TRW slugs, stock 915 heads, .550 triple springs adj rockers, Torker intake 3310 Holly with 2” spacer, Hooker fender wells with 12” extension, stock 68 street Hemi vert, 4.88 8-3/4, 10.5/ 29 M&H slick S/S springs moved into frame, Carter pump. All steel car one van seat, heater removed, hoop with side bars. Best driving race car I ever had, stopped on a dime, KH brakes up front. 1981.
I put the engine in a race 68 Dart (big tires and 4000 vert) went 7.01 in eight, about a tenth and a half slower that his built 440. We ran mostly 1/8 mile

Centerline and LSA are the same on those 508-509 cams, IIRC. If it says 108, then use 108 for both. Then choose where to move the centerline when installing.

overlap comes up spot on in the wallace calculator 292 108 lsa

I bought one of those cams from Bob Mazzolini back in the day, when I started installing and degreeing it wasn't that cam, it was the 533 solid lifter cam in the 509 cam box
Mopar never mark those D.C. cams in any way for us, the consumers and racers, to I.D. them on the bench before installing them
Same thing later on buying a 590 solid lifer cam with lifters from him, it was a 557 cam in the 590 box, I called D.C. on that cam and was told that Mopar had switch vendors and they knew those new cams didn't have the proper lobe lift but they insisted they were still great cams ARHHHH I took that one back and ended up having to argue with Bob to take it back and refund my money back to me, that was the last Mopar D.C. cam I bought.

If you install that cam, and measure it, it likely will not have/match the advertised 0.050” duration. Probably closer to 242.

A 292 cam from the 70’s should have been a Racer Brown SSH-44.
I ran one of those for a while…….. it was a good cam.
My actual measurements had it as about 304@.006 and 244@.050.

That .533 cam has slightly more duration than a .590 solid.

As Fast said, back in the early Direct Connection days thr Racer Brown SSH-44 was the 509 purple shaft and I believe (don't quote me) the SSH-25 was the 484 cam with about 241 @.050.

In the early DC Engine manual they referred to the 509 as the 4 speed bracket cam and the 484 as the Automatic Cam

the 484 was a great 440 cam and the 509 got used in a lot of tight converter cars but still worked pretty decently.

The typical hot 440 set up for the Day was the '67 closed chamber 915 heads shaved at least .040" with a 509 and a TM-7 /4779 (750 DP) and a 340 or 383 (10 3/4") 'Road Runner' Converter. We used to put the cam in +4 rather than straight up. With 3.91's or 4.10's you could bust almost anything pretty consistently...Until the W2's started becoming available.

Before there was a Direct Connection, Chrysler carried the SSH 25 and 44. Later they released the Purple Shaft series cams, two offerings with specs close to the Racer Brown cams.

The early Purple Shaft cams were made by Camcraft and were excellent cams, circa mid 70’s.
Not sure who made them later.

The engine manual shows the Mopar part number for the SSH-44 as P3690812.

I don’t know how far back that number dates it.

The first use of the SSH series cams was the -25 and was for the Hemi, around 1967/68, part number was 2836158. I’m thinking the “P” prefix started early 1970’s.

In fact many of the earlier non - P numbers were simply carried over by adding the P.

i have used the SSH-25 cam in 383's, and at 4* advance installed, that works great !

The engine manual mentions that the new replacement for the street hemi cam came out in 1983.
That’s cam number- P4286631.
The 248, 260, 272 cams are all slightly higher part numbers, so my take on that is they were released around the same time.

The MP 484 and 509 cams are P412 numbers, so they should be from a bit earlier.
