The pic, is the Toyota Turbo rod, and the Carrillo Porsche rod, the bolt, is a Oliver Rods 7/16 cap screw bolt.
I will be turning this rod into a cap screw rod, the rods will be drilled and taped for these bolts, and then clearanced, for a very large stroker, and the small end will be bushed for a .927" Chevy pin.

What stroke is the crank?
What pistons do you plan to use? Do you know the pin heights available?
What is the intended RPM range?
Headwork- Are you going for super vlume or Hi Velocity?
All these things and more will determine the best rod for the application.

And unless you have an 82+ stroke crank the rod ratio will be a killer and you won't have anything for chamber filling.

The bare minimum length of rod to run with an 86mm crank is 5.7"
Now.. With that said do you have any idea the issues that you will run into just fitting an 86 stroke crank? For starters the profile on the rod cap becaomes ULTRA important because collisions between the cam/connecting rods are your biggest challenge.
Now, the other issue is a set of cylinder heads that will allow that big of a stroker to turn 8K... according to bore size... My MassIVe heads would even have a hard time with that job in many applications.
Running this much stroke requiresan extensive amount of patience and I certainly do not recommend it for someone that has not built a smaller stroker TIV before.
BTW- Chances are that a smaller engine would be not only easier to build with less hassles and expense, but would also make MORE power.
We really need to talk, I can make this so much easier for you, especially if you do indeed want to go to 86mm stroke- but I would not... Keep it 80mmm or less and use a MassIVe combo, no way you can go wrong.
