Hi, I'm also in the middle of a 440 swap into a /6 Scamp. Schumacher kit all the way. Sorry to hijack your thread, but i"m sure we can both use the info. I noticed that the heater fan motor is a TIGHT fit. Trying to use Mopar Perf finned valve covers, anyone use these? Think they will work if I grind the fins in the area under the heater motor?
