DBecks

Okay so I apologize if there's already a thread on this but after days of searching I couldn't find a helpful answer. So I'm putting a 5.3 lm7 into my s13 and am now working on cleaning out the chassis of unnecessary items (AC, wiring, interior parts, etc.) and an issue I have is one of the nipple/hose fitting things that comes off the heater core through the firewall into the engine bay broke when I pulled the SR out. Now the car is never going to see the street again and will only see events when it's above 50 degrees out so I won't need heat so my question is how much will it affect cooling if I take the heater core out and block/loop the hoses on the motor? I'm going with a Mishimoto KA24DE rad with a dual puller fans shroud. Would I be better off replacing the heater core or is it fine to bypass it on the motor and get rid of it?? I've never dealt with cars with heat before really so apologies if it's a noob question but everyone seems to suggest the core helps a lot with cooling.
