I need cam help and any advice or opinions

Hi guys new to the site and need some major help on my cam im getting tomorrow!!!!

For starters i have what i believe is stock 350 mid 70s-late 70s block with flat top pistons, 462624 heads 76cc combustion chamber i think 200cc flow 2.02 intake/1.6 exhaust valves, very light porting done, a edelbrock rpm performer air gap intake with a 4 inch high rise and a mr gasket one inch spacer, a holley 3310-3 750 cfm vacuum secondaries carb, hei vacuum advanced distributor with 1 3/4 hedman long tube headers to a 3 inch outlet with 2 1/4 inch dual straight pipe exhaust no muffler or glass pack, th350 stock transmission stock torque converter gm corporate 10 bolt front differential and gm corporate 12 bolt rear differential (gov lock) with 3.42 gears

I am trading for a gm performance cam P/N 24502476
Flat tappet with matching lifters
.435" Int./.460" Exh. lift
212 Int./222 Exh. Duration @.050"
112.5 Lobe Centerline

(Only info i can find online besides what the guy sent me up above)
This hydraulic flat tappet is used on the 350-300 and 330 HP special performance engine P/N 12355345, and 12486014. The duration at lash point in degrees (intake/exhaust) is 320/324; duration at .050" tappet lift (intake/exhaust) is 212/222 and maximum lift with 1.5:1 rocker ratio (intake/exhaust) is 435/460. Valve lash is zero/zero and lobe centerline is 112.5 degrees.

What rpm range will this cam give me? Am i gonna be able to run it with stock valve springs in my setup and can it still be used for street, light off road, light towing, and fun cruising?

Also any suggestions on a shift improver kits likw Trans Go (not a shift kit) that will tighten my shift pattern without slamming gears on the street and breaking tires loose going into second gear?

Please any info on this cam and my setup would be greatly appreciated thanks in advanced for taking the time to read all this
