144 pistons dont fit 200



I just bought some 144 pistons and they dont fit in my 200 what up with that? I thought the 144 pistons where interchangable with the 200's :roll:
If anyone wants to buy a set of 6 brand new 60-64 flat top falcon pistons just hit me up!
Not to sound like a smart-a**, but I'll bet that you discovered that they are too small. The 144/170 both have a 3.5" bore while the 200/250 have a bore of 3.68". Also, 144 pistons can't be used on a 170 due to the piston skirts. The 170 pistons eliminated these so that the pistons don't hit the crank. Sorry to be the bringer of bad news. Take care,

Well, you bought an item that won't fit. :oops:

The 144 and the 170 share the same 3.5" bore diameter while the 200 bore is 3.68".
