Are stock heater boxes incompatible with a 1914 motor? I have a recently built 1914 in my 72 SB Convertible, only 140 miles on the engine so far. Today I installed a Berg Temperature Dip Stick and after 10 minutes on the freeway (65 MPH-ish) the new temp (oil) light starts to flicker on. The outside temp was about 85?F, I assume that it it's getting a little too hot. Is it 'normal" for a new motor to run hotter, until it's sufficiently broken, if so how long does this take? The car has 040 heads, 110 cam, dual Kadrons--main jets at 145. I have an 009 distributor but the SVDA from Aircooled.net is on order along with the vacuum ported Kadron throttle body. The motor also has a Bugpack ceramic header with single quiet pack and the stock heater boxes. Is the exhaust system too constrictive and causing the overheating? Or is it likely something else??? If I need larger exhaust, is
1 1/2" OK so I can still have a functional heater or does this size motor require larger and therefore J-tubes. Any assistance, feedback experience and advice is truly appreciated.Thanks, Theodore
