I have an intake from one of my customers that he wants me to sell. Looks brand new. Supposedly off of a late 30's flathead 6 chrylser. It is a 2 carb with 1 9/16" openings for the carbs. The exhaust ports (3) are 1 1/4" dia. The front runner has a single bolt hole at the 7 o'clock position: the centre one is also a single bolt at the 6 o'clock position and lastly the rear runner, also a single bolt at the 5 o'clock position. Distance from the bolt hole on the front runner to the bolt hole on the rear runner is 17". Apparently there are 2 different length engines? Have I described this one good enough for somebody to tell me what it is. I am going to advertise it in the classifieds for sale. Thanks....Don
