1973 Mustang Grande, Light Pewter
351C H code w/FMX transmission.
23k original miles
So I have this 73 Grande with 23k original miles, and as many of you know, these are 351c engines are turds with all the smog restrictions in place (California car). As a project, I've been tempted to pull the heads to have a machine shop install hardened valve seats. Of course, that would be a good time to upgrade the cam, and timing gear/chain. I've been tempted to ditch all of the egr equipment in the process. Do you think doing any of that would diminish the value, and ruin the originality of the car?
