So, being an old school 1st gen sbc guy, you always had a radiator with an overflow tank to catch coolant that escaped from the radiator for whatever reason. Nowadays new systems have tanks with a hose that connects to the radiator that catches overflow and feeds it back as needed with temperature changes. Trying to design something for my LSX 70Z. Anything special I need to concern myself with the LSX platform? Trying to decipher all the terminology, "overflow", "recovery", "recirculating", and what system I need... What are ya'll using for your LS conversions? thanks.
