With the Holman-Moody clue I was able to do some digging. That one looks to have 260 degrees at .050" lift and is cut on 108 degree lobe centers. Not really a street friendly cam.

Maybe it wasn't street friendly but it must have sounded awesome at idle.

All kidding aside a 3/4 race cam has only 12 lobes instead of 16 it was done to save weight.

I find cams designed with "sounding badass" as a primary consideration to be ridiculous.

The same goes for conversations I read online with "It's a street car, but I want that nasty chop" and similar.

Then you just have to install some Hollywood mufflers.

I get the desire for chop - does sound cool but were I to build an engine tomorrow - camp choice is for performance first, if the chop comes with - great. If not, I'd not compromise on matching the package with a mismatched cam to get the chop instead.

IIRC - Comp has a big and small thumpr and requires requires a 2800 stall and 9.5:1 compression, headers, intake and gears for their big 351W Thumper cam - I'm sure it specs out as "the right choice" for certain combinations or targets, I just wouldn't know what that is. They tout mid-range so stop light to stop light?

From what I used to see for primarily street driven cars, people tended to over cam, over carb, and not put enough into the cylinder heads.

If you want a rough idle, pull a couple of spark plug wires and give the carburetor about half choke. Lots cheaper than throwing a bunch of mismatched parts together. If I can't see a torque gain on my dyno, I don't need some aftermarket part designed primarily to put dollars in the manufacturer's pocket. P.T. Barnum was right about a sucker being born every minute.

Yep... a stock low compression small block in a near 4000 lb car with 308 gears, add a big thumpin' cam, a 750 Double Pumper and set set of large tube headers... Pooch!... a well tuned stone stocker would outrun them... heads & rear gears are everything!... choose the rest of the combo to compliment them...

Hot rod shop used to tell me…”speed is expensive, how fast you wanna go??”

Oh yea, most definitely. You immediately know who's into "looking cool" or "sounding cool" and who really knows how to make power.
Everybody talks Horsepower. I wanted big torque numbers on my street cars.

Since this thread is already off the rails, no harm no foul. Is Clarksville Speedway still open or are there condos there now?

Still open.
Big thing for alot of people around here.
They also flip the Clarksvegas gunshows between the speedway and the NG unit on 41A.

Viva Clarksvegas!!!!

I'm an FE guy myself, Built this one for my '68F100 swb, it's just a 390 bored .060 but she's a beast.

Kind of amazing these days really. See that 2000 hp, 302 cubic inch Ford and it's not exactly unique. Lots of 1000+ HP builds out there of all flavors and done, relatively easy with FI these days. Streetable engines.

As a kid, a 400hp engine was "something" and a 500hp street fox body was considered to be pretty radical. Now Ford's selling Predator engines at 760 hp as a crate motor.

Seems like a PILE of advancement over the last 30 years, maybe as much as any other time in ICE history.
