To introduce, I have gained my uncle's 97 4.0 Aerostar. It's a great van, but it has 130k miles on it, and one of the pushrods is worn enough to tick. It's not an easy task to remove an engine from an Aerostar, but I plan on doing it as soon as I can find another motor with fast burn heads to rebuild.
My question is- where can I find better quality parts? Does anyone make aftermarket camshafts? Are there any computer tuning programmers or chips for this year?
My biggest issue is the valvetrain. This engine is notorious for wearing pushrods and rockers. I haven't cracked mine open yet- but I'm wondering if anyone has tried to overcome this problem with roller cams if any are available? Do 2.9 adjustable rockers fit? If so, are these any better about wear?
That's about it- thank in advance for all your help [thumb]
