build a 408 stroker motor out of it, your block with the 408 stroker rotating assembly. 10 to one pistons, trickflow twisted wedge heads, victor intake, 750 speed demon, 1.6 roller rockers, comp cams camshaft(call them for the matching cam). that will get you to 400 and some,

 

when I built the 351W for my 52 f-1

I got a 393 kit from these guys

Go Fast Stuff - Kits

I then had is balanced and got a custom solid lifter cam ground from comp cams and ran world products cast iron windsor SR heads with roller rockers and used a wieand stealth intake with an edlebrock 600 cfm carb.

IT didn't cost me much cash but is a GREAT running motor.

it runs good enought to grenade 3 trannys and 3 rearends.....I now have a full roller dynamic racing transmission that is holding up and am going to swap in an n-case 9" center section as soon as I find a locker for it (right now I am running a lincoln 9 3/8" rear)

 

here is a video I took a while back when I first put it in the truck.

It runs a bit quicker now since I have made adjustments and other upgrades to it.
