that cam you have is verry mild for your motor, you need to look for around a 480-490 lift and try to stay around 230 duration if not a little less and this wont give you any problems like power brake vacume and it would still have a nice lope, the cam i went with in my 355 was 501-510 lift and 240-246 duration 110 lsa and its pretty radical i wouldnt recomend anything over 230 diration for what you wanting to do with it, hope this helps

Comp cams has a Extreme energy cam that is 268/280 adv dur 224/230 @ .050" with .477"/.480" lift. With a 10.1 355 and vortec heads with a air gap manifold and 750 holly DP, you can get about 430 HP. This cam has 15" of vaccum at 800 rpm. I was shifting at 6400 rpm before the cam really fell off. Throw some 1.6 rockers on to it and you would get .508"/.512" lift with great streetability and gas milage(when cruising). They also offer this cam with the 4-7 swap, which helps cut vibration down at higher rpm. Which equals free HP lost back to your flywheel.

I have a 292 .501 hydraulic Comp Cam in my stock 350 with torquer 2 intake and 650 dp and is perfectly reliable. Drove it like that everyday for about a year till I pulled it for my 406.

The cam you speak of is the XE268. It is still fairly mild. I have the XE274 and it is very streetable. It is about the limit for power brakes and 2500 stall. I ran a 12.7 @107 with the setup in my sig. I am planning a cam and stall swap shortly and streetability will be much lower. 245@.050 duration .534/.534 lift and 3500 stall.

keep the duration under 230* (@.050) and something with a 113-114 lsa, probably something around .520-.530 lift to take advantage of the larger runners you have on your heads.

The wider LSA would work great with fuel injection but on a carb motor try to keep it 110* or less for maximum HP.

well its going to be a street car so i would think he might want a smoother idle, but i guess 110* isnt so unbarable
