400hp 351w N/A
Man is this possible? Daily driver, 94 351w roller block. What heads and cams do YOU! recommend? Would a balanced bottom end help? Lol, Forged internals? Will be stroking to 408 but thats yrs to come.

Its not out of the question. A nice head and intake combo, have a custom cam made for it and you'll be knocking on the door. It would need at least a 185 head although i would step it up to a 205. The lower end is good in that power range as is, although building a 393 can be done relatively cheap. Are you racing it? The big *** mains of the 351 mean you cant spin them as high, but the neutral balance will help by not slinging around extra weight

That sort of power can be made using all off the shelf parts including heads.
Just use enough intake port volume, at least 195cc and 205cc is better.
Use about 245 @ .050 duration cam with about .600 lift.
If you are planning on racing at all, use at least a 750CFM carb. I prefer mechanical secondary's.
Forged pistons are always a good bet for anything except a grocery getter.
New rods that are quite good can be had for not a lot more than what 'rebuilt' rods cost.
Now, get to work........

Yea I found out it was possible myself. I ended up boring my 351 .30 over with KB hyperuetectic(if I'm saying that right) pistons and a .555 lift XR comp cams with my E-205 heads. My machinist is putting it together as I speak can't wait to drive the end result of my NA street monster.
