yep

The 4.2L crankshaft will bolt right up to a v6 mustang block

You can also bore the engine out to .60 over to get a 4.3L bore total

Pick up alot of torque by doing this

Larger bore requires larger pistons.

www.moranav6racing.com he actually has stroker kits all the way to a 4.6L for your v6.

You want forged rods and pistons anyway.

If you decide to stroke your 3.8 with a 4.2 crank you might as will get a 4.2 short block and then proceed from there and unless you a5re going to go with a high boost Supercharger or go over 75-100 shot of nitrous forged is not a necessity but a nice addition if you can handle the addition cost.

its pretty cheap to stroke but if you are gonna do it do it right

that does not sound like to bad of an investment to me. im getting around 2500 when i sell my mg here in hopefully within a month. would you recomend stroking or just mod the 3.8? i still have another car i can drive plus when i get income tax im probably going to put another 1000 in the car after that ill be done for a while though. so stroke or mod??
thank you for everyones input.

i probably wont bore though
