Stock radiator cool enough?
I am in the process an engine swap. It will be a 355 with aluminum heads. I have a dual fan setup from my TPI donor. Will a stock replacement radiator be enough or should I upgrade? I do plan on upgrading the water pump.

Stock fans will be fine. I'm running a single TBI fan on my 350 with stock 305 radiator, and it cools it fine.

Old post. I installed a 355 in my 84 T/A as well. I've found my Single electric fan doesn't keep the car cool when the AC is on, otherwise it works just fine.

I have stock dual fans and radiator and it works perfectly, the owner before me was an idiot and wired the fans backwards and made it so they were blowing air and not sucking it through the radiator
