347 STROKER vs JUNKYARD 351W-SBF DYNO DUEL!

Back in the 70's I was a chevy guy then a mopar guy and it always amazed me at how often these ford 302's used to come along and give us such grief by being beaten by them time and time again to the point that I eventually became a ford guy too and still am after all these years. I still like chevies and mopars as well and there's nothing like American iron and just the sound of these engines reving up still excites me no matter which brands they are.

Stunning results with the 351 Edelbrock package

Love when you do sbf testing

You don't do things wrong , man . You test . I like tests , especially when someone else is doing it 🙃

1 thing not mentioned is the 347 is a fresh motor with 30 over pistons, 351 is junkyard standard bore low compression with who knows how many miles.

I love your graphical presentations of the results. That is the ONLY way to see any differences. Thanks.

Unless one is constrained by space limitations a 351 is the better choice for an all around performance choice. More torque and horsepower in the everyday useable range all the way up to 6000 RPMs in this example PLUS, big plus, the 351 is much less stressed than the 347 and will be far more durable over the long run.

I'd take the 351 hands down ... more peak torque, and more HP and torque across 80% of the usable power RPM band. "HP sells cars, torque wins races" - Carol Shelby

GREAT VIDEO RICHARD!!!! SOMETHING I AM CONSIDERING FOR THE FUTURE!!!! THANKS FOR SHARING!!!! I LEARNED SO MUCH!!!!

Thanks for the vid! I like both engines. The Windsors are beasts. As always, it depends on your specific demands placed upon your specific engine build. My old 1981 Bronco is going to have different demands placed upon the same powerplant as a 1984 Mustang GT 5.0.

Very well explained. I’m a strong believer that a motors potential to make power is solely based on its displacement. All other things being equal, the higher motor will win. If you put the right heads/cam in a 351 it’ll rev out to 6500 too. And make more power than the 347. Keep it up. You know your stuff

More sbf

Great video. Final thoughts are right on target (in my opinion). Keep em coming Richard.

I thought the same thing about the stroke. Dam bro u are the man wish I had ur guided info years ago.lot of respect!

Super informative tests, and videos!

Wouldn't we all like to see a comparison test where both engines had the same spec cam, and the same heads. Plus the same compression ratios. That way we could judge the configuration differences on an apples to apples basis.

Love the 351w’s especially in my Foxbody. The junkyard 351 with the Heads and cam swap with the 750 carb is very impressive gains!!! I don’t have the head and cam swap but I run a RPM intake with a 750 carb. The torque difference between it and the 5.0 is crazy.

351 with Edelbrock top end package, bang for the buck!!

Like the videos. The 351 combo here looks nearly perfect for my 94 f150 build. Lot of other factors near tho, rod stroke ratios!! Think that's a big factor in the curve too. That 9.5 deck height and 5.969 rod makes for a good street motor. After years of watching 347's self distruct I'd never have one tho. Wrist pin in the oil ring land! 7500rpm passes, weak stock blocks, po boys need to build one motor that will stay together. Been awhile but I think 347 rods are 5.4" at best! Just think about a good set of heads on a Dodge 360 with those 6.2" rods! Run forever if you don't spray it to death!

One thing I noticed when going from a 351w to a 302w was a very obvious improvement in handling and steering response with the 302w
