    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.

    The old systems with overflow tanks also take care of recovery as the engine cools and takes the coolant back in. There is nothing new there. The old system does it all. 1970s technology was amazing for new people who think today's tech is an improvement.

    You just need a radiator with an overflow bung on it and an early 70's Camaro tank and hose. (So you can mount it in the factory location and it fits the contour of the fender well.)

    It you use some aftermarket overflow tank.... The hose needs to go to the bottom of the reservoir and the top of the tank is vented.

    70 Camaros didn’t have an overflow bottle so you will have to fab a bracket or maybe one from a later year will fit.

    ^^ no the 70 did not, but the inner fender had the holes for the 70-74 version. That’s what I’m using
