Hey guys,here goes,I have a 69 super bee 3.91 gears, 2,800 stall auto,383 stock.I have a 67 440 engine to build.My combo so far is indy rotating [Edited by Moparts - Keep it clean].440cu to 500cu.I want at least 10to1 to 10.3to1 comp.I was thinking of running the edelbrock rpm hesds and intake.My problem is cam choice.I want a drag car idle but I dont want to over cam itand I still want to drive from town to town with no problems.I hate going to car shows and having a car that idles like a station wagon.So this is what I have so far. comp.xe284h 240 246 .507 .510 110 2,300 to 6,500rpm or lunati60304 voodo 234 242 .513 .533 110 2,200 to 6,400rpm with tti headers 1 7/8 inch Has anybody ran these cams? or is there a better cam out there for my set up? I also thought of ordering a custom grind thumper cam from comp. cams.Any way I would like to hear your thoughts.Thanks R.B.

My combo is nearly identical to your planned build except I have a little looser converter. I have ran 7 different cams in it to date, starting in the 240* range. I now have a Scott Brown solid that is .597/.593 and 263*/273*. I think it is very streetable after making 2 important adjustments. Idling in gear is the biggest challenge for this size cam. I have about 28* advance at idle and had PTC loosen up the converter to let it idle higher. If you like a bumpy idle but still want tolerable steet manners, the cams I have had in the .580ish and 250*ish range may fit the bill. With uncut Eddies, the cam will pull good to about 5,800. With an A&A 5,800 RPM governor, I leave my car in drive and (with good tires) ran consistent 7.2s with this combo in my 70 Cuda. I have been buying my cams from Scott Brown and my converters from PTC because they know what to send me to perform like I ask. Call Scott Brown, tell him what you want the cam to do, and that's what you'll get. Oh, and I think the hedders are a little small.
Master, again and still

Thanks for the info.dave&ahy it sounds a lot better than andyfs idea.Do you think I should go the extra money and run the indy ez heads instead or is it worth it for a street car. indy ez 270cc int. 2.19 valve eddies rpm 210cc int. 2.14 valve and a 2 inch tube header Any other hot sounding streetable 440 combos out there that will make 500hp or better?

As noted, the more cubes, the bigger the cam needs to be...You need to decide on the cubic inches, and how far your going with the heads. From there, we can give you a better idea.
My favorite cam in a street strip +0.030" 440 was the MP 0.590", but in a bigger engine, you will want more. The limiting factor on the street with all cams IS the convertor. Too tight, and the engine will be a dog and even difficult to drive, too loose, its no fun either.
We just need a little more to go on.

What kit? More precisely, what stroke do you want to use? I'd run higher static ratio if it's a 4.25 stroke and RPMs. You wont have good drivability and poor idle... And the cam's you listed are smallish for even the 3.915 stroke IMO.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.
