    Cooling setup for a 68 cuda with a 440

    hi cuda guy, all mopar V/8's came with either a 22" or a 26" radiator and corresponding shroud. all the air conditioner equipped cars had the 26" radiator. when it comes to keeping a mopar "cool" "bigger is always better" so your really need a 26" radiator for your 440. if you use an original...

    water circulation question

    kiss... i would offer a thought to "shutting off" the water flow through the heater core. water flowing through a heater core does provide some additional cooling of the engine water. that is why you can often turn the heater on in a car that is overheating and gain enough driving miles to...

    opinions needed on this idea

    hi oldkimmer... i don't know what to think about the "thermostat, no thermostat" debate. i know years ago, i ran several cars with no thermostats when they had overheating problems. but the more research i do on this topic, the more complicated it seems. because there are so many other...

    mr. retroron... well... i don't know how to respond to you other than to say i did not intend any "snide remarks" directed to you. i think when i offered my opinion on the effect of using and not using a thermostat i stated i would like to hear from other FABO members on this issue and that i...

    opinions needed on this idea

    well... finding the answers to questions has always been an interesting challenge to me. most of the research i did on old mopar and chevy engines, small blocks and big blocks found that those engines liked to operate between 160 and 200 degrees - but no hotter. with that said, here is a...

    opinions needed on this idea

    i'm still curious if any other "technical" FABO readers have an opinion on the "no thermostat makes the car run cooler" debate. however, i can say with some confidence that "old" V8's - like your 440 - DO NOT like "heat." in fact, all V8's from about 1958 to 1978 do not like heat. in the...

    opinions needed on this idea

    brian... i'm curious about your response.. years ago when i was still living in "the hills of w.va." taking the thermostat out of a car that ran hot was always the first "remedial" action - and always was good for at least a 10 degree temp drop. back then, i believe there were two...

    opinions needed on this idea

    well ... there's always the "take out the thermostat" and "keep the heater and blower motor on" in traffic route... in the Marines, we used to call that kind of mechanical work "combat repairs"...

    Help - I'm almost giving up! Won't start.

    hi famous ff... first off, forget about the heater temp. control - cool to hot. that lever is all mechanical and simply turns a water valve on the heater core to let radiator water flow through the core. there are no electrical circuits connected to that. remember the basics for...
