I have a 351W in my 65 mustang that has some slight work done intake,cam,heads worked, headers, and I am thinking about doing a 393 stroker kit in it. Is this something that is worth the money. I would like to have around 400hp at the flywheel and still be streetable. It has a 2500 stall and 3.55 posi rear. Also if I do the 393 stroker would I need forged parts since this is more a pleasure car that will be road hard now and again off a stop light? Thanks
The 390-ish stroke is about the biggest you want to go. Some say the 408, but I'd rather keep a little extra bore on the side for the next rebuild.Nothing makes torque like a stroker. I certainly miss the 347 in my daily driver! The engine can be very streetable with good power/torque with the right cam and you won't need forged internals for street use as you describe. A nice Scat or other such stroker kit will drop in with a little machine work and you can retain your headers, heads, intake, etc.HTH...Mark.

I was thinking about just buying a scat cast crank 3.85 and keep my rods I have in it now and get a set of either cast or hypereutectic pistons. Now I wanna keep it around 10.1 compresstion I don't wanna go over that so I was plannin on getting a set of dished pistons. Now what would I need to machine? I've heard you don't have to with a 393 but maybe I'm wrong. But I don't want to have to pull the motor out of the car again for this project so would I need to pull it to do this?
