Is a 6.0 Iron block bored over .060 with 4.060 Forged Ross Flat Top Pistons,
Eagle Forged 4.100" Stroker Crank 6.125" LUNATI Pro Billet Connecting Rods to much. It believe its a 424 ci and was wondering if it is ok safe to build? Its an N/A with no NOS. Thanks in advance.

Any tech advice???

 

Ttt....

 

its bored 60 over its bored to the max, you can put sleeves in cylinders if not already has them, if so im pretty sure you cant do anything else to it, but again im not sure.

 

you would need to get the block sonic tested to see if it could be bored that much..

 

I am ok with the bore size (that is what mine is), but I WOULD sonic test the block, JUST to be safe.
I do not like any mroe stroke than teh 4.00 on our deck height blocks. Just leaves no room for pin on the small end. For a NA motor, and a NA motor only, you could get away with more. At that length, you are leaving VERY little room for any crown on teh piston to work with. In other words, with that much stroke, and short compression height, it would not be a very good FI piston.
You can always run a shorter rod, but not a big fan of that either.
