Need advice. Would like to upgrade to 306-351

[302 LX Eric]

281, 289, 302, 306, 331, 347, 351, 357, 377, 392, 408, 427, 460, 514....

Chose what's best for your application and for what you want the car to do with all things considered. tarmon8r is right, a 351 or 351 based stroker will generate more torque than a 302 or 331, but is that what you want?

NYC1, my recommendation would be to really think through what you want the car to be at the end of the day. Where will it spend most of it's time? Dragstirp? Street? Dailydriver? And how fast do you want to go? Corner-carver or full drag car? Maybe somewhere in between? What will make you happy?

Once you come up with a vision of what you want your Mustang to be, you can start planning from there. You may conclude that a 331 or 347 is not what you want. Maybe a 351 or 351 based stroker is the way to go for you - maybe even more cubes. Maybe you want to stay N/A, maybe not. Stroker408 brings up a good point by laying out all the pros and cons to keeping the motor N/A or supercharging or even using N20.

Take your time making your decision. Talk to others who have different combos. Visit your local race track. Keep you eyes out on this board for what people have actually used and what their thoughts are.

And most of all, enjoy the entire process. It's very rewarding, albeit sometimes pricey, but in the end I think you'll find it all worth the time and effort you put into it.

Good luck,
E
