View Full Version : 89 T2 Block: Can I use these pistons and rods?

I'm probably going to be gettting an 89 block that's been all honed and redone and such, with standard bore.
I have some brand new Federal Mogul pistons (swirl head type) on 85 rods. I know the commonblocks generally use floating pin pistons (or something like that) and these rods don't have that...
the question is, can I use those rods and pistons in that engine?
Thanks!

Second Question:
Any reason not to use those pistons/rods in that engine? :)

Weak rods, thats it. The floating pin issue is tossed around whether its good or bad. Personally, pressed pin or floating pin is fine. I like floating pin as I can change my own pistons-no machine shop needed.

Huh. According to Gary, these rods are as strong as the t2 rods of later years.
And I quote:
The best rods to use are the TII ones (which require a floating pin piston) or the 81-85 2.2 rod (which do not). Basically the same rod except no bushing for a floating pin.
Why do you say that the 85's are 'weak rods'?

the 85 rods are not weak... Only issue is floating pin which tends to "emit" wrist pin noise after a while.. Damn near sounds like rod knock but with a better rythem!!

Sorry, my bad, I speed read the thread, you guys are right, :p
I think the wrist pin issue is just wear, look at SBC,s Small block Mopars etc, they all have pressed pin and no issues. My last used engine had pin knock-floating to boot. To each there own, I just prefer the floaters as no money to swap pistons, which I used to do alot, hehehehee, :nod:

Cool. Thanks, guys.
I was worried maybe the rod ends where it meets the crank would be a different size, or something silly like that.
