Re: Urgent, need opinions on my new crate engine

So since I have the hoses running from the intake to the heater core and then back into the waterpump I don't need to worry about the coolant bypass?

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??
