New member question re: engine performance

[vanoochka]

Hi,

I recently purchased a used Superformance Mark III with a 351 W Crate Engine, 380 HP and 9,400 miles. I am thrilled with my Cobra, but after driving it for a month now, I've decided I would like to get a little more "ooomph". After doing some research, think a 408/480hp (or so) would do the trick for me.

I am not mechanically knowledgeable at all, have a lot of questions about this, and so am asking for advice.

Should I try sell my current engine and buy a new crate 408? If so, can anyone recommend a seller who is reasonable with a good reputation? To my ignorant eyes, the prices seem to be all over the map for what appear to be comparable engines.

or

Should I have a local performance shop install a stroker kit and upgrade my current 351 W? If so, what are the best kits? What is a reasonable price to complete this project? Does anyone know anyone you would recommend in Northern California? This option seems the lesser expense, but does it open up any problems that a new crate engine would not?

The car will be used as a weekend fun car. I won't be driving it hard, but will occasionally want to open it up (and so the desire for a stronger engine).

Thanks in advance for your help,

van
