Any imput on what type of fans/pump would be awesome. I have a 69 Firebird with a 400 pontiac/Muncie 4 spd/600 E-brock carb/mild cam/headers/e-brock intake etc.

What radiator are you running? I have seen many people using OE electric fans from Lincolns, Taurus, and a few others. It depends on how much room you have. Derale has a dual 13 inch unit that pulls 4000cfm, it's a little over 200 bucks at summit.

For the fuel pump you can use any mechanical pump from Edlebrock, Holley or a stock replacement one. Just be sure it puts out the right GPM and pressure. A regulator with a gauge is always a help just to be sure. No need to go electric for the pump with your set up. But if you wanted to there are lot's to choose from. Holley blue pump, Aeromotive, Carter, Summit has a complete fuel system with a pump (electric), filter, regulator and line for about 240 bucks. Part number SUM-PUMPKIT7A. It includes -6 braided line (20 feet) and AN fittings and clamps. That would be more than enough to feed your engine. Some of the external electric pumps are VERY noisy though. I have not used any of the summit brands so I can't tell you how loud this one is.

Just be sure to run your fans on relays.... I've seen many people try to run them without and that's serious no no!

I just added a SPAL PWM fan controller to my Nomad... has the first fan come on only half speed and slowly speeds up that fan IF needed - once Fan #1 goes full steam - fan #2 comes on... it also has them BOTH come on when your A/C is on... and has a 'cool down' cycle for 30 seconds after you turn it off... Nice system for nominal additional cost IMHO. Really keeps the noisy fan issue at bay most of the time.

My radiator is 16 tall by 23 wide so I'm limited on size. Why not runa single 16 fan?

There are tons of options for singls fans for you. Take a look over at Summitracing.com and see what they have. You should be able to get everything you need at a reasonable cost. If you see one you like click on it and it will give you the dimensions, CFM ratings and cost.

But like Greg mentioned above, use relays. Don't just do a direct wire with an "on/off" switch.
