Anybody out there in hamb land running a stroked SBF? Looking REAL hard at stroking my 351W to a 393-408 something along that line I dont have the motor tore down yet for rebuilding so I'm not sure where my bore is going to end up ect.. I was wondering about longevity and fuel economy.
The 351 isn't know for economy. If you buy good parts, longevity isn't a problem. I'm a fan on CHP. The 408-410 is highly regarded but more money than a 392.
Build the 408 on a regular basis. I am a dealer for the the Eagle kits. Longevity would still be ok but if you juice it to 408 it all depends on the rest of the parts you choose for mileage !!! >>>>.
I'm going with factory cast heads (1970 heads) ported with the bigger Chevy valves got a edelbrock air gap manifold probably 650-750 cfm Carb. Not sure on a cam yet. I'll have a It with probably 3:73's in the rear. Not gonna race but would like a little more then the next Guy with a 350 Chevrolet.
Not sure on the 351, I believe they can make good power when stroked. I have a 302 which I am going to have done as a 331 stroker.
I got a 347 factory engine Runs great but I've noticed lately its starting to blow antifreeze out of the overflow when stopping after long drives on the highways probably not related
The 351W is a strong and popular ford engine. It seems like the 408 is the most common stroker size. If you want to piece your own parts together the 393 might be cheaper since you can use factory 351W rods and off the shelf pistons for a 302 with the correct crank. Keith Black hypereutectic pistons are very good for the money for a street car. The only downside of the windsor is the 3" mains if you want a high rpm engine. I wouldn't go more than .040" over on a factory block without a sonic check. The early blocks had stronger main webbing and a shorter deck height. Seems like all the factory blocks can take about 550hp and after that everyone has a different opinion. I just wouldn't use the factory heads on a stroker unless you have to. Good luck,
