Hi
I am thinking about building up an 426 small block for my Challenger.
It will be based on an R3 block bored to 4.25 with an DragonSlayer 3.75 stroke crank.
Has anyone on here built up an engine like this?
Or have information on who to contact about setting up this combo.
Also the engine would be need to be able to handle large amounts of NOS as my engine now does.
