Now this is a rattler. Idles a 3000 rpm and has a 12000 rpm tach . Old school small block.
2950 lb car
4.30 rear gear
4 speed manual
Bored .030”
Edelbrock aluminum heads
Dual plane rpm intake
750 double pumper
Long tube headers
I want a rowdy street car that I could take on the strip if I wanna play around a time or two. I’m okay with it if it’s almost too rowdy for the street

If you’re intent on running a HFT cam, that’s probably as good a choice as any.
These days, whether or not its actually available can be a part of deciding what to use.

Wouldn't be very rowdy but should be a fun combo.
in my mind, this is saying solid roller. and i don't think a 750 is gonna cut it, probably want an 850 up top
if this was how frisky i was feelin' i'd be on the phone with ken at oregon or racer brown or somebody to grind me something. cam wise, everything is a compromise and with an off the shelf grind you're making more compromises or compromises in areas that you don't necessarily need to or want to.
the big momma is a little aggressive, but i don't think it's really that much more rowdy than an old MP 292 piece. it'll be fun though if you have the compression to support it.

This could easily turn into a “be careful what you ask for” scenario………
But in the spirit of “rowdier”……
Racer Brown SSH-44 on a 108
I would go with a solid roller in the .640 lift range.
I've never ran one though I've run a few cams that are very similar. I think it would be a good rowdy Street grind and it wouldn't take a ridiculous high spring pressure to controlled valves similar to the 484 purple cam.

I run the 292 cam in my dart sport and it runs pretty good. Wish mopar still had the purple cams readily available.
it's funny, everybody says that... and then i put one up for sale and all i get is crickets.
everybody says how great they are, and had one back in the day, best thing since canned bread but noooobody wants to drop some coin for 'em.

Aww man I somehow feel like the throttle response is right there.. you just touch the gas and its "blap"

Mancini had a few of the popular ones re-popped.
Edit- looks like they only show the 474 cam for the SB.
There are 5 options for the BB.

Those old Maco bikes are badass….
The 103 C/L is opening the intake valve quite early. Do you have the Intake Closing angle for that cam? - Degrees after bottom dead centre.
It doesn’t specify. The lobe separation is 109
This one has a custom head with hemi chamber/ enhanced squish band and a Teddy Boyko ported cylinder.
