The engine had 117k miles
It's carbed with a Holley 600 and Holley performer intake.
The stock lifters had a lot of carbon on them, I have been in the process of soaking each one overnight in chem dip and its been working real well so far, keeping each one in the original position.
For the springs I was going to go with these:

I don't want the shop to have to do any machining and these seem to be highly recommended.
After reading all this, I wish I could find a new stock cam lol... I hate to keep the one that's in there for the time being.. then again maybe I'll get a used stock mustang cam and replace this one, they're both used so the risk is the same and if I was to drop $300 on a good cam then I guess I need to consider lifters too now which is another $113, so the price just keeps rising. I can do it down the road i guess. hmmmm
Hey thanks for the free advice even if it's bad news I appreciate it, looks like I woulda wasted a lot of time+money other wise.
oh and I'm not looking to go too high in the RPM's, normal stock range limit, I don't want to break anything, not looking to bring it to the drag strip more then once or twice. I just like to go through the gears on the street and know the power is there when I want to get on it.
