Can you get Muscle Mustangs & Fast Fords
agazine where you are? They just dyno tested a 393W stroker with about a dozen sets of heads. Look it over.

Standard TFS-TW heads (2.02/1.60) plenty for a 393W. AFR 185 (2.02/1.60) and AFR 205 (2.08/1.60) very competitive with TFS.

The guys are right about the rod length though. For a stock 3.50 stroke street motor, it's a waste of money screwing around with a longer than stock rod. Look at it this way. Every SBF with a 5.7" rod would give its' #1 piston for enough deck height to use a 6" rod that we 351W's get stock.

If you go with the stroker, use whatever rod comes with the kit. Actually, for a warm street stroker motor on a budget, get the Scat cast steel crank, and KB hypereutectic pistons #364 which are specific for the 393. Give the stock forgings a street motor workover (magnaflux, sides ground, big ends ground round, ARP rod bolts, magnafluxed again) rebalanced, and bolted back into the motor. For a 6200 RPM every once in awhile motor, this is plenty. For a 6500 RPM every weekend motor, use the aftermarket rods, and forged pistons.
