Hi, I'm new to Fords, but I understand that a 351w can be stroked to a 393 pretty readily using a stroker kit from a wide variety of sources.

I'm using a '72 351w for this build, what flow potential will the stock heads have? It seems like the stock ford heads are suited more for a 302/289 than a 351, let alone a 393.

I guess I'm looking for advice here on which way to build the engine...I can stick with a 351 displacement or build the 393. The restrictions are that I want the engine to remain stock appearing (except possibly for headers and and any aluminum parts would be painted engine color) I'm also looking to keep my FMX (unless it's totally unsuitable for performance use...again, I'm a GM guy, so help me out) and I also want to keep the 3.00 gears in the 9". So...this engine needs to be built for street torque.

Any help? Thanks in advance.
