What is the most CID you can get from an Iorn 6.0 need Stroke, Rod Length, and piston size.

I am Planning on a large stroke maybe a Large piston. Just really looking to see how big i can go

I currently have a 6.0 block with a 4.1 crank 6.125 length rods and a 4.04 piston. Billet Mains with main studs

A good sonic tested block can go 4.060". If you don't mind running thinner ring gaps, you can run a 4.185" or 4.250" stroke. This would give you 433 cubes or 440. It's not a very desirable set-up, but could be done. In reality, the 4.100-4.125" would be about as much stroke as you would want to run.

So what I already have is a basic good set up without spending alot of money on the block and or a warlock block

Your combination will make 420cu.in. There are a number of people including myself, who have used a 4.125 stroke and a 4.030 bore for 421cu.in. All the 402's that I've built have made 500 plus to the wheels but the 421 will outperform these engines hands down. Do a search for Tosto Racing and Tom the Roofer. They run 9.7 and 9.6 N/A with this engine.

Yea, your combo is good. Nothing wrong with a stroker.

The 421ci (4.125 stroke, 4.030 bore) is that with 6.125 rods?

well I run 9.9 at 137 already. I would just like to have more CID before i spray the hell out of it. Thinking about maybe going to a solid roller also... The only thing I want to do is be able to drive the car on the street daily if i wanted too

And I love it when someone ask whats it run and they never believe it... i just think it is funny

Does anyone sell a Complete rotating assembly for the 421 combo and how much
