318 Camshaft

Hello all. Just wondering what is the best camshaft for a 68 Coronet with 67 318 (Weiand 8007 Intake/Edelbrock 600 cfm carb/Summit Headers 2.5" dual exhaust stock 920 casting heads (new stock/springs guides/seals) and stock pistons. Transmission is a 904 with a 11" PTC 2200 stall low gearset and TF-2 shift kit. The rear axle is 8.75 and 2.76 gears riding on 245/60/15 tires.

Right now I assume it has a stock type camshaft. I have been thinking the K6900 might be the way to go to use the stock springs and pushrods but, I also thought about the Whiplash from Hughes but, we do drive this car a lot. What is your guys opinion? It is mostly street driven. This may be my first time changing a camshaft. Thank you in advance.
