And i've decided that I need my truck to be a real towing rig. So I'm thinking i should go with an hx40/hx60 twin setup and intercooler off a powerstroke. If there any better suggestions to this, I'd like some advice, but for now this is what I'm thinking. Will this setup run new era 435 cool and clean enough for towing, or should i go with the 370's? And where could i find the intake and exhaust piping to hook a hx40 and hx60 together?
