Default 350 rebuild Cam ideas

I'm looking ahead to a rebuid of the 350 currentl in my car.
What would be a decent Street cam for a 350. Idle to 4500-5000 RPM.
I figure it will need .030 over pistons and .010/.010 under on the crank.
Just went thru Summit and saw a Lunatti 307A1LUn http://www.summitracing.com/parts/LUN-307A1LUN/
What do you guys think ?
I want some balls with basically a stock rebuilt engine. I have a E prformer Intake and E 1405 Carb which I'll probably be using.
Thanks in advance.
Andy

what compression is your current 350? maybe give the year and head casting. I have a feeling that cam will be fine.

I would use my TC-03-HF.
Duration @ .050..............214/221
Lift @ 1.5.......................450/465
Advertised Duration.........264/270
Lobe Center ...................112
Overlap..........................43

Is that Lunati cam $185 just for a cam??? Save $45 and get a better cam in the process! JMHO.

I have a '74 Ventura that I have been toying around with. It has basically the same build as you describe. I do have a 2500 stall torque converter in it though. I did a backyard overhaul on it about 4 years ago and put a Summit 2800 cam in it and liked the amount of pull it had. Being the knucklehead that I am, I never put any zinc additive in it, and ended up wearing a couple lobes smooth on it and had to replace it. So I opted with a Comp Cams XE262 this time. It definitely feels like it has a bit more top end to it, but the bottom end grunt does not feel quite as strong. I have been a bit afraid to really wind it up since I have stock rods in it though.

I know that Ace has done extensive work on the 350Ps, I think I would give strong consideration to his suggestion.

Hope that helps,
Derek

I would agree with Ken's ideas too. I didn't have his advice earlier, but I actually bought a cam with nearly the same specs for my 350 build. I got a Comp Cam 265DEH to use with stock heads. May be a bit much for the 17 heads, but I'll find out soon enough.

Default Cam ?

Stock (at the time) 72 350 2bbl.
I just put on a Edel. Performer intake and 1405 (600cfm) Carb. and and a Stock HEI Distributor.
It has stock 7H1 heads. I looked up the heads and I think it says 7.6 compression and maybe 80cc chambers.
When I do get to rebuild it I assume it'll be bored .030 over. Summit sells a couple (Sealed power Kits, I assume it means Pistons and rings) but I it is a summit rebuild kit.
A the time it has the stock TH350 (don't know the stall) which I will probably have to rebuild also. Right now it has a 2.56 open rear but I have a posi carrier and was thinking 3.08 gears.
So I suppose I need something that would beef up a basically stock 72 350. It is a street car and may never see the track (cept just to see what it'll do).

What I did was fill out the comp cam form on their site and then posted the results here and got everyone's feedback. After hearing the comments I was comfortable with my decision.
Just my 2cents.
