Hey everyone, need your help selecting the right cam for me. 69 351w stock heads, air gap intake 600cfm edelbrock carb, tri y headers. Would love a nice lope at idle without sacrificing low end. Looking at all brands. What do you guys think? Thanks
It’s hard to have a lopey idle without sacrificing low speed torque since that sound comes from bleeding off cylinder pressure with overlap.
You might also run into an issue with needing a looser converter and your gears being too tall.
Check out comp’s thumpr series. They’re actually engineered for this application where you have an older iron v8 and want the idle sound without all the hassles of upgrading everything.

If you switch to a roller cam, you can avoid the oil issue and get a more radical profile.
Thanks for the info, Lopey idle is low on the list reliability and performance is key. Looking at the comp cams high energy 268 or the xtreme energy 268. Is this too much cam? Thanks

Leaning towards the high energy, xtreme calls for 2200+ stall.
I think that is a good choice given what you are going for. You may even get a little of that sound you like.
We need to know if this is an automatic transmission or a standard. The camshaft selection needs to be compatible with the torque converter if this is an automatic.
If it is a stick, no issues.
If you like the lope but want reasonable street manners, you might consider a Thump’r series cam:
It is an auto. Stock converter.
Take a look at this.

Thanks for the info I will take a look into it.
The EDL-7182 might be a bit “fat” for his application, 224/234 duration @.050" and the notes say 3000 stall for best results. I’d stay more in the 218/224 duration @.050" range.
Having said that, the Thump’r I suggested has a lot of duration too.
A compromise is always required when wanting “the sound” while working with a stock driveline setup.
Yeah, you have to compromise something.
Personally, I’d just run an RV cam in it or something that idles smooth and makes more power across a broader range, forgetting about the noise. But that’s like telling someone how to eat their hot dog. Maybe you don’t like anchovies and jalapenos on your dog like I do.
Ya that ugly word compromise lol. I think I am going to go with the comp high energy 268. Seems to be kinda the best for what I ak doing right now. Should be easy enough on the stock valve train but still wake her up a little. Thanks for the input guys.
I had a Comp Cams 268H-10 cam in a 302 i buildt, and i was really really happy With that cam,
I buildt it with top end kit from Edelbrock, RPM heads, RPM Airgap intake, put in new flat top pistons with valve reliefs, that engine was Incredible quick in response on the gaspedal, tryed to launch it and shifting manually one time, had to let off the gaspedal as i couldnt coordinate the hand to move quick enough to follow the rpms from 1-2 gear, had to let off the foot.
Unfortunately for me, the shop that hohned the cylinders and assembled the crank and pistons did not gap the pistonrings, so it got ruined, too late in the season, so i ordered a 345HP crate engine from Ford Racing With roller cam, and that engine is not nearly as quick and responsive as the old one i buildt
Jan,
You alright buddy? Yuor post semes a littel of!
Too quick with the writing, pc could not keep up and register all the keyes i punched 
(not sure what`s up With my pc, as it wants to have Capitol letter on many Words in the middle of a centense too) all edited in my other post now 
I think he will be very happy with that cam selection
The Comp 268 with 218 @.050 and 110 lobe seperation probably won’t get you quite the sound you are looking for. I would tend to stick with a single pattern cam in this application. My choice would be the Competition Magnum 270. That amount of overlap would probably get you want you want without losing much bottom end. Comp says it’s the biggest cam you can use with a stock convertor. If good hole shots are your interest, then put in a 2500 stall.
This car will be just a cruiser that needs to have a little something to back it up. I believe the gears are 3.25. Now the plan is to do an aod maybe next winter with a set of 3.90’s maybe 4.10’s so I can do a converter at that time.
I didn’t look at the magnum line skipped that one for some reason. That 270 almost sounds like a decent setup for what I am looking to achieve with what I’ve got.
I have the Comp Cams 268H in my 351 Windsor, it was a 2 barrel motor , I replaced the stock intake with a Edelbrock Performer and Holley 1850s 600 cfm carb when I rebuilt the motor. I had the stock converter in the FMX rebuilt to approx a 2200 rpm stall speed.
I drove the car for the 1st year with the stock 2.76 gears, off the line it was not real impressive but once it was moving it pulled nicely.
3 weeks ago I upgraded the rear end to a 3.50 trac loc , this made an incredible difference in the off the line performance and overall feel of the car.
As far as idle quality it has a slight lope,pulls about 15 -15.5 inches of vacuum at about 750 rpm.
3.90 or 4.10’s are no good at all without OD in the trans. 3.25 is a good ratio, the highest numerically that you’ll want with no OD.
Unless the gears have been changed, 2.75 or 3.00 are what these cars commonly come with.
