They were on sale for $62 w/ lifters! not sure if they still are. FWIW I ran the 224/234-465/488 cam in a pretty stock 440 in a 67 coronet w/ 3.91 to 12.90. It's a good cam it has power form off idle to 5400. I use one again in a minute.

I'll keep this very simple a caveman could do it. Ask yourself.
What's the factory grind numbers on a stock factory cam?
Now take those numbers and for the duration, add 10%.
For lift, add .050" to those stock numbers and what do you come up with?
Keep your choices within those parameters and you will have one sweet street machine.
That comes out to be a pretty big cam though...
237/248 at .50 and .505/.520 lift. Especially when we're talking stock converter, 3.23 gears, and manifolds.
5% is more reasonable I'd say, and would be similar to the Crower 271 cam.

Robbins,
How small of a Summit cam. How big do they go?

how about none of the above. look at a mopar performance 272-.445. its ground on 112 centers, installs at 110cl, 224@.050, 129@.200. very underated profile. works good with stock heads, valve springs, seals, and rockers. i use one in my 4000lb+ 69 r/t with stock converter and 3.23 gears. performs decent and has nice driviability. another option is comp cams magnum replacement, #21-305-4 222@.050 .464lift on intake, 226@.050, .464 lift on exhaust, 110 lobe centers); a real tire fryer when installed at the recommended centerline (106cl).

I thought the 272 was 231/231@.050? I agree, I think its a really good cam, but summit has it listed at 231. Im thinking about buying it as I believe it was in the 440 in my GTX. Just want to make sure summit doesnt have it listed wrong, might make me rethink it if your spec were correct.

summit is just repearting mopar performance's "revised" numbers. the true .050 number is 224@.050, just like it was stated years ago. i've run 13.13 @ 106mph with that cam in a 4000lb+ 6/9 r/t, stock exhaust, stock converter, 3.23 gears, stock heads, 9.3:1 compression, six-pak, 225-70x15 t/a radials, and still get 15+mpg on the road. the 21-305-04 cam is a good profile but don't install it 106cl (as comp cams recommends) in a performance role. 110cl would be better for 1/4 mile use.

I'd go for the lunati voodoo you listed. having the aggressive ramps with short adv duration will make it a nice sleeper with a nice idle and great low end (yay cylinder pressure) while having as much power as the larger grinds. I wouldn't use the summit cam unless you're on a verry tight budget.

FWIW my buddy put together a 69RR w/ stock bottom end 440 (probably 9-9.5:1) w/ Eddy heads, RPM intake and the VooDoo cam 513/533 I think? pretty much they same stuff I had as far as trans, stall and gear and I whooped him. 12.90@104 to 13.13@102. just saying  I think the VooDoo would like more compression and higher shift points.

i've ran that cam ground on 110 centers and really like it, but it may be a little soft on the bottom for a big car. neverthe less its a performer for a near stock or moderately modified 440.
