Thank you all Moparts guys and a special thanks to 451Mopar for your competent and comprehensive advice.
I have started to look for suppliers and prices.
And you are right when looking at costs of high strenght bolts + rod machining some other considerations starts.
Buying a stroker kit which include brand new crank, rods, pistons, rings and bearings fore a reasonable cost.
Have been looking at the Eagle kits offered on e-bay, but it's another jungle to pick the right.
Any advice on stoker kits ?
Will consider it during christmas and take the
decision after new year.
Thanks moparts
