I am considering buying a 1970 mustang grande with a 302 V8 and 3 speed manual transmission. Body is in great shape besides passenger floor pan and normal surface rust underneath. Most of the major components are already off the Motor (but are included) and it's all stock. If I buy it is would want to pull the engine out, tear it down to clean and rebuild while adding to it. Headers/full exhaust and a cam is all I am thinking of as of now. Does anyone have any advice on this? Best headers and cam? Anything else I could/should do while I have the engine out? Trying to keep the spending down to a couple grand. Thanks for your help.
