Connecting rod question

[Erickz]

Are the connecting rods used in a Mini Cooper 1275GT engine usable/the same as in a MG Spridget 1275 engine?
Thanks

I believe so, same as Austin America rods. I ran them lightened with ARP bolts in my GT5 Mini for years with no failures.

There are some 1275 cc Mini engines that have their crankshaft rod journals 1/8" larger in diameter than those found in 1275 cc Sprites and Midgets.

I assume that the connecting rods would be different for these engines ?

Charlie wins! Yes, the big end is bigger by 1/8" so well done Charlie!

I'm building a LP1275 race engine right now, and posting the build on a MG Experience Midget car forum, if want to follow the thread, here it is.
