More 65 Valiant 273 to 360 swap questions

You can use all the 360 stuff for your alt, use a 360 car pan works just fine, if your car is a V8 car, the hooker headers are horrible in my opinion, i have them on my cuda, i run the TTI in my 65 Signet, tight fit but they work good and you can access the bolts and oil filter.
