That, combined with some tales of cracked 302 (5.0 Mustang) blocks, got me thinking. Has anyone ever cracked a 2.5 or 3.0 block? I've heard that con-rods are a potential weak spot, but with a 400+ fwhp 2.5 out there, it makes me wonder - where's the limit? With TVR and Noble both having used the block, can we expect to see some really crazy parts in this block?



Except I have yet to hear about anyone breaking a a stock rod. Tom didn't...the Nobles don't, and I doubt I will either. From everything I have read/heard the rods being weak is an assumption.




The rod BEARINGS are the weak link.




well im new but if were talking bout the 2.5L SVT Duratec i have broke a rod that started with the rod bearing but i did drive on it for 20+ miles before it went soaring through the side of my block .. it had only 113,000 miles on the block . no mods just bone stock..
