So I did something that will cause a lot of anger among both Chevy Lovers and Ford fanatics, I installed an SBC 350 on my 1963 Falcon after some mods it fit. how ever after only 2 months on the road with it the engine failed forcing me to buy another engine. 2 weeks in with this engine it began to overheat after only 5 minutes of idling it begins to overheat. brand new everything radiator short water pump head gaskets already checked, I cant seem to explain this. and it also makes a rattling sound when I try to accelerate. any help will be appreciated.. and I know i will get those ugly comments about the conversion.
