The Hemi cam in the 70s was a .465 225@50, 80s .471 228@50 and ran power breaks no problem.
Have a great day Iowan

Yep these are the hipo 346 heads ! I have actually been considering using some of those other components you mention that are available to me [/quote]
Thought so...the markings on the heads have always helped me. It sounds like you're right on track. This is probably too detailed, but if you can find any of the goofy old metal cal custom type plug wire looms, and maybe the T handle valve cover bolts they would look right at home. having looked at alot of working mans/budget hod rods when I was a kid, this is the kind of stuff they usually seemed to have.

That 509 cam might not had been the best choice for street performance, but it sure sounded like it was! That bad boy gave the motor a sound of its own.
Like a lot of stuff back in the day, the performance level highly depended on the guy doing the tuning. Some guys had the touch, and others pretended they had the touch. It seemed as though the guy with the touch could make any combo work, and the guys without the touch might have ended up with one combo that worked pretty well, so they stuck with it.
If you really want performance, I'm not so sure any of the old cams would stand up against the newer stuff, but if you want to look and sound the part, the old stuff is hard to beat. Gene

Gene I agree and that’s true today too. My original plan was to use the Hughes whiplash cam. But I had a thought that I may just keep it old school. 😁

I were going to "soup up" my B engine back in the 70's what cam would I have used ? I'm surprised no one said to use a 3/4 race cam Hahaha yeah. That’s the first description I was ever given of a performance cam - in a ‘68 camaro 😂

I sold a friend a Mopar Purple Shaft 284 street hemi grind for a 383 motor going into a 1968 Charger with power brakes, he owned a automotive garage and it was for one of his bigger commercial customers Son car. I help him degree it, it had right at 4.5 inches of vacuum idling at 850 RPM in gear That's strange... must have been something else wrong since you degreed it for him. Huge vacuum leak maybe? I put that exact same Purple Shaft cam (284/.484) in my basically stock 383 rebuild. It idled with a very minor lope at 13" vacuum at 750 rpm! I was told by a local Mopar Purple shaft lover, he is very knowledgeable on Mopar V8 B&RB motors , that Ma Mopar had change the LSA on that camshaft, RB&B motor street hemi 284, 484 grind back in the mid 1990s or so I bought several other Mopar brand camshaft later before abandoning them all due to the "590" grind not having .590 net lift I called them, Mopar hot line, about it and I was told they had change vendors and they knew it wasn't .590 net lift now but they had dyno the cam and they weren't worried about the loss of .040 lift

the isky 1012b was the '64 s/s wedge race cam; 320 degrees duration, .520 lift, 108lsa, a lot of cam. the 1012b was superseded by the racer brown stx series; stx21, 22, & 23. the ssh25 and 284-.484 are identical for all practical purposes. the real issue may be how much head modifications your willing to do to run a high lift cam. there are 114lsa versions of the 284-.484 and 292-.509. in my opinion, none of the above. What about the old Street Hemi grind 280-.484 ?

509, Torquer 383 intake, 3310 holly, 383 with stock 67 heads, Manley pop up .30 pistons, 68 street hemi converter, 4.88 gears in a 70 all steel Duster. 11.67@117 mph. Idled nice at 600 rpm (after carb work) all back in 1979. Tried 750-850 dprs, never made any difference. It had the M/T valve covers and stock dist (one tiny spring) with a MSD 6 and the yellow Accel coil and wires. Hooker fender well headers with 12" extensions. A little 2 gal Moom tank and a Carter electric pump, 3/8 aluminum line. I might have had $500 in the whole car. Forgot to add, snorkel scoop on the steel hood. Makes me wish I had it back. get the 509 and don't go overboard with the carb, no Russel fittings, no braided line, no wire looms, fiberglass fan, Moroso air cleaner, no shiny stuff.

You can't get the old Street Hemi grind cam from MP anymore. I ran one in my 413 when I rebuilt it in 88, it was in my 300 and had zero problems running power brakes or the HVAC controls. The new version is different.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Back then mine where Racer Brown or General Kinetics. Never owned a purple cam.
In theory, there is no difference between theory and practice. In practice, there is.

hi
crower monarch in my 413 in 1969-70 ! Used one too in my 383. Later swapped it for a Stage III solid lifer cam. Was also running Stage III heads. Had to modify the intake for that of course.
