Honestly, Aaron, if you're looking for 350+ horsepower, I'd just start getting some aftermarket parts from Ford Motorsports and build up a "new" Ford 351W. Not an "aftermarket" 351WOW.

Read up on Ford Motorsports' 351 Crate. If you want to DIY, just copy that. It's good for 385 no problem. That's a good amount of power.

If you start listening to all the people here (yeah includin' me) and heeding all our advice, you're going to end up with a 351W stroked to 427, Paxton blower, Nitrous fogger, 12:1 compression, etc... and you'll end up making 8 million horsepower for 49 seconds and then poof.

I'd say most of the time if you start gettin' fancy with upgrades and performance pieces w/ that motor, you're going to start breaking the 400HP mark.

Hell, the guy who dyno'd my 408 didn't even flinch calling it a "mild street/strip motor" and we're over 500 horsepower. MILD!

We wanted 500 horsepower and 500 TQ. We got it. Tony (dyno man) was saying "but if you just tore those AFR heads off and knocked down the CNC marks, put a Weiand intake on it, put on a Holley 850DP, and knocked the heads down another 4cc, you'd be at 600. Put the RIGHT heads on (205's or even 225's in his 'humble' opinion) and a Dominator carb, and we'd be staring down the barrel of 800 HP.

There's always a way for more and more.

Duplicate the crate 351, that'll be your best bet for 350-400HP.

If it's not fast enough, pull it out and make it faster.
