New Guy Looking For Opinions Regarding A Camshaft

I wont bore you guys with a long story, so im keeping it the shortest I can.
In 1995 my dad bought me a 1969 Mustang Grande. My plan was to paint it with some money I had back then but the engine broke a couple of month of driving it. A friend of my brother fixed the 302 V8 engine.
What I remember from back then:

• 302 Block was bore .40
• He put a 1969 or 1970 Mach1 351w Cylinder heads
• Edelbrock Torker II Intake
• Holley 650 double pumper
• Forged pistons (I think 9.5 compression)
• He ported the exhaust of the heads and made bigger some oil holes in the engine block.
• Roller rockers 1.7 (not sure about the height)
• Duration 280, Lift 512 Competition Cam (almost sure this is correct)
• Hydraulic Flat Tappet Lifters

This engine was only used for a small 15 minutes trip and was removed from the car. 17 years later we are finishing the car and start up the engine. It works great BUT the cam its too aggressive for what we are looking for right know.

What I recently added:

• Shorty Headers
• Aluminum Radiator with electric fan
• C4 Saturday Night Special Converter (which is too low for the cam)
• Flowmaster American Thunder 2.5" dual exhaust
• Steeroids Rack
• 13" Baer Brakes on all 4 corners
• 9" Rear posi 4.11 (not sure about the ratio)
• Fiberglass Hood
• Classic Auto Air A/C Kit
• Wheels 17 x 8 Front, 17 x 9.5 Back

Question:
What Competition Cam (or other) you guys recommend?????
