First time down the track

Tiny camshaft, but other than that, seems like cookie cutter parts. What iron heads are they?
280 is stout flow out of a factory iron head.
But with the lift of your cam its unlikely your seeing a big chunk of that.
Short of putting on a good hooking tire, the first thing i would do with that combo is throw that cam is the trash can.... lol

I had a somewhat similar combo, 9.5 ish compression, Similar type cam, bone stock eddies( not close to as good as yours are if they flow 280) 750 and M1. This on a stock stroke 360. With more convertor and a bit more gear it went 12.20’s at 109. 3300 pounds
Put a real camshaft in it, mildly ported the heads( and milled to get up over 10 to 1, and installed airgap. Has now been 11.20’s at almost 119, still stock stroke and nothing fancy
