I am getting ready to buy my first hotrod. I am going to look at a el camino. This may sound simple to some but how do I tell the differnce from a 305 and a 350 also how would I tell what transmision it has in it is suppose to be an automatic. That would be a th350 or th 700 wouldn’t it how would you tell the differnce. Any help or advice would be greatly appreciated.
