Re: Big Block overheating
I drive a 70 SS 468 Sta. Wgn. with a 700R4-3:08 Rear gear. AND it has factory A/C.
Cooling system-- 100%--1970 to the last detail. ( 772 fan, Clutch , and shroud, 811TX water pump, copper four row rad, Or just like my one owner LS-5/ M-22 with A/C.
Car has over 35.000 miles city & Highway, NO cooling issues. Parked in the sun on a hot day with the A/C engaged, It never gets hot.
I still like the 43 year old ideas, WHY? = They Work.
Remember the stock 772 fan & Clutch NOT ONLY pull air through the heat exchanger they ALSO remove the super heated air from the engine compartment, VIA Exiting the air at the rear of the LEFT & RIGHT exhaust manifolds. Why does this system work?
When " ALL FACTORY ITEMS " are in place, It operates like your furnace, Big blower motor along with Duct work.
Just something to think about. Think a lot and be KOOL...........
