  2. It's time to give back

    Classic Talk
    After picking all your brains for so long I think it's time for me to give back to you fine folks and share what I have experienced. From my short lived mustang ownership experience I have these bits of information: - I installed the Pertronix 3 ignition with the Flame thrower three. I used...
  3. 1984 mustang gt40p heads. What cam, roller rockers do I need?

    5.0L Tech
    I have a 1984 5.0 with a 89 5.0 302 carb'd. I have a set of gt40p heads I am going to put on. I want to put a cam in and change to roller rockers.

  4. Prepping Rocker/ Mirrors Bumpy Surface for paint

    2005-2010 Mustang Talk
    I'm looking at doing a little mini project this weekend, and I'm considering paint matching my mirrors. When I paint matched my sideskirts, I didn't worry about sanding down the bumps or anything, but on the mirrors, I want them to be glossy. I have some minor experience in sanding for body...
  5. loose rocker arms- why?

    5.0L Tech
    Recently did a carb conversion on my 91 5.0. I figured it would be a good time to put new lifters and pushrods in. When I finished up the motor, and fired it up- the lifters and or rockers were clattering. I thought that maybe the lifters had to prime. After about 5-10 minutes shut the car off...

    5.0L Tech
    Which roller rocker arms do you guys recommend with Edelbrock Performer 60379 heads, what supporting upper and lower intake will make the most out of these heads. Ive also got a E303 cam. Also, do i need hardened pushrods with these heads? :headscratch:
  11. Just curious as to what others use as a reference

    Classic Talk
    A while back I had restoration/rust repair/structural work done my 68 convertible --- badly. Looks like, in order to get everything to fit properly, I will likely have to pull a lot of it apart, learn to weld it back together and go from there. Because of the work that has already been...
  12. 302 rocker problems

    Classic Tech
    I have a 1970 302 block with a 1985 rotating assembly and cylinder heads. We were trying to lash the valves but I cannot get the rockers tight enough so that the pushrods stop moving. The hydraulic lifters always seem to bleed out and then give it enough room to spin the pushrods again. The...

    5.0L Tech
    Ok, so i just walked home from the shop due to 2 broken valve cover bolts. Any idea how to get the rest of them out? Drill and EZ out the only way? Anyway, I originally went in to adjust the rockers due to valve train noise. I have the Ford SVO rollers and adjusted them all with the technique I...

  15. smoke after valve cover gasket replacement

    5.0L Tech
    So i just changed my valve cover gaskets, i had to pull out to upper intake manifold to get close to the rockers. I changed the gasket that sits between the upper intake and the lower intake while doing this as well. Now initially i had forgotten to put back the pcv pipe into the lower intake...
