RE: Poly 318 heat riser / cold starts?



Who would even need such a thing? If it was a daily driver and you lived in a northern state given to fits of sever cold id say ok but I don’t need that on my vehicles and I start and run my cars during the winter if its nice ill drive them around otherwise I just let them hi idle till they are warm. Usually I have to move equipment around in my barn so they get started an ran every so often .    as I live in northern Indiana we get plenty of cold wet weather. Only ever had my plow truck carb ice up .  so I cut off a 5 gal bucket short so the hood would close and force air to come up around the intake.. that was a 2 fold fix it also kept the aircleaner from plugging up with snow as I was busting drifts 4-6' hi to try and get from our farm to my house.  That was the only time ive had icing issues.

Subject: Poly 318 heat riser / cold starts?

1970 LA 318 engines had a system of heat riser, choke, heated air intake including the heat stove and air cleaner to allow quick starting in cold temperatures and to prevent carb icing.

What about the '62-'65 Poly? It a simpler approach with a choke and exhaust manifold heat riser. By now the exhaust manifold heat riser spring has probably deteriorated or broke and the valve rusted stuck.  Heat Riser Repair Kits are over $200 for NOS.

Any tips about an aftermarket or DIY substitute for the exhaust manifold heat riser?

Thanks,
Gary H.
