Default 142k mile F14 cam swap???

Looking for some info from people that have done higher mileage cam swaps. Mileage? Did you keep the stock lifters? Any issues? My '98 TA has 142k miles which are mostly highway. It runs fine and has great oil pressure. I want to run a F14 and wanted to keep the stock lifters for now, since you have to take the heads off. I already ordered my Patriot gold spring package. Opinions?

A buddy of mine put a F14 in his '98 with 116k miles and it runs 10.80s on a 150 shot with stock heads. 142k miles is a bit more than him though.

I would use the stock lifters until you are ready to swap heads. Ripping off the heads ONLY to change lifters is a big time waste!

Note... If you have extra time and don't mind doing all the work, go for it.

Tell him the same thing when his lifters collapse and fubar his motor, see what he will think of that.

Before you do a cam swap 98 Black TA, I suggest you do a leakdown and compression test to determine the healthyness of your motor. If it is still within acceptable specs then go for it, but I seriously advise to change lifters especially on a 98.
you'll also need pushrods, timing chain, LS6 pump, head gaskets, head bolts, other gaskets...etc...

You don't have to change them. Cheap, realible, fast. Pick three. You want to keep reliability up? Change them unless it's worth it to replace the motor/cam if one fails. If you understand the risks and still want to do it, it's completely your call, but considering all the things that COULD go wrong during a cam swap, you should be doing everything in your power to maintain as much reliability as possible.

the LS7 lifters(ls1,6 replacements) are about $120 shipped; just yank the heads, install some ARP studs, GM mls gaskets, new lifters

I have 132,000 and just installed the Patriot 226/226 cam and valvespring package in my car and it runs damn strong so I don't see why not. As long as the car has been taken care of you should be fine, just my opinion though.

I would change them for Peace of mind. Thats just me though. I would rather take the extra time and 120 bucks since you are already in there anyway. I mean its that or if and when a lifter colapses you are replacing a whole lot more than just the 120 $ lifters. You know, that whole thing. Good Luck

Having two sets of lifters go out on me and losing a cam, id suggest replacing the lifters when you do it. For the time and effort, save till you can pick up a set of cheap heads to upgrade to at the same time.
