My bad.

 

What about getting a stroker kit to make it a 426?

 

Anything is possible, just need/add $$$$.

 

Along with a good bit of TIME to get it all swapped over, installed and tuned, unless you are planning to pay someone to do it for you..

 

That motor probally wouldn't be very street friendly lol, that's alot stroke. I've seen a couple and Hughes sells a kit but it's pricey. They are torque monsters though. Your stock trans would **** itself just looking at that motor.

 

I have read for a 4" stroke crank in a magnum a small amount of clearance machining is necessary to clear rod bolts or something. I have also read that anything more than a 4" stroke crank takes a lot of machine work just to prep the block to take the crank. In my personal opinion, a 4" stroke is the way to go for a street driven motor.

 

Something else to take into consideration as long as you're going to the trouble and expense of stroking it, rod length to stroke ratio. This is a pretty good explanation.
