Also on another note, this new engine comes with a holley 670 carb. I know Edelbrock likes 5.5-6 PSI of fuel max. Does Holley require a max PSI?

I already had ordered a Edelbrock mechanical pump to use with the 290 HP engine because I was going to use my 1406 carb....would that still be a good fuel pump to use for the Holley or should I get another fuel pump? If so, suggestions??

That is correct. Keep your thermostat bypass (your heater circuit) flowing coolant and you will be OK. I do advise you to get a 5/8" to 3/4" heater hose adaptor and keep it in your glove box in case you ever blow a leak in your heater core OR heater hose so you can keep that circuit intact by running the intake manifold hose to the suction side of the water pump.

If you don't want it rattling around in your glove box, get a zip-tie and fasten it to one of the heater hoses.

Yes, that would still be a good fuel pump.
