Which cam would make better power?
Im having trouble finding a roller camshaft that I can use with my stock heads. Im thinking about trying the lt4 camshaft but its pretty mild. ~.460/.480 with 1.6 rockers and a 203/210 duration at .050''
Im gonna get that OR a hydraulic comp cam high energy 268h grind. It has a .454/.454 lift with 1.5s and a duration of 218/218
which of these cams would make better power? Can I go higher on the lift? I will be getting head eventually but not for awhile.

Both of those cams seem a little mild for a 350. I have a 305 and am going to get a 212/218 with somewhere around .444 lift with a 112 LSA.

The LT4 will work fine but you will have to use 1.5 rockers or pull the heads and machine the guides

Im trying to find something with more duration. Since I have carb I can go alittle higher.
Im gonna go ahead and get a cam now because I cant afford the heads just yet. I will eventually change the heads and when I do I might change the camshaft also.
Both may be mild but they are alot better than the .365/.380 TBI cam thats in my motor now.
I could get the heads with the money Im making from selling my paintball gun but I was gonna use that for a posi and gears.
Head/cam or posi/gear/cam??
