Hey Guys,

I am restoring a 70 Convertible SS clone and putting in a 454. I have been told that if I put headers in the car I need to make sure the engine frame mounts are for a V8 other then a 307. My question is how do I determine if the frame mounts in the car are 307 or not? There is a motor in it now, but I wouldn't be able to tell you what size cid it is.

Anyway to tell quickly?
