What to do with a 351W block

id go with the 392. i guess they work pretty good.

With those 185s I would stay with a 392. I am kinda biased though.

Why go 393 when you can go 408??? Your going to have to notch the block for both so I'd say go with the 408 by all mean's. Depending on the rest of your combo the 185's will hamper the true potential of a Windsor stroker, but you will still make tone's of power. Infact on a street engine the 185's would actually work great on 408. I've seen a 408 with Out of the Box AFR 185's, 10.1:1 Compression, 282HR Comp Cam, Victor Jr. Intake and a 750 Speed Demon make a little under 490HP at the flywheel, which is awesome for a street cruiser or even a weekend warrior. Of course 205's would be the ultimate way to go, but I woudn't be scared to build a 408 with 185's at all. It all depend's were you want your power band. Obviously the 205's are going to flow better and make more high RPM Power, while 185's on a decent 408 are ging to give you one hell of a torque monster. Overall DropTopR I'd say go with a 408 and your 185's, and you will have one hell of a mean street engine.
Infact I talked to AFR awile ago and they said you could go either way on a mild 408 in term's of 185's or 205's. It's a matter of personal preference and were you want your power band.
