New Engines: 557 or 572
I am thinking of build a couple of spare engines and can't decide which stroke to go with.They will have convention 24* heads and whipples with a solid roller. I have 598's now and I really like the torque of these, but it seems all of the big name builders are going with The 4 3/8 stroke 557. Will there be much difference with this over the 4 1/2 572.

You may want to watch this, they could be your back ups as well? :evilb: |
Re: New Engines: 557 or 572
How about some 557's from Mercury... :D

Re: New Engines: 557 or 572
The smaller Stroke is suited for sustained high rpm.
557,s love to play in the upper 6000 rpm range. 557,s are my platform of choice. But then again I like Budlite. :drink: |
Re: New Engines: 557 or 572
Now send me the 5.0 whipples your getting and I will put them on these 557,s with these CFE chief heads, solid rollers.
This is my next setup. |

I smell a bargain in the works. :eek: :D
You may as well go ahead and price those old junk quad whipples to me as well... :evilb: |

Re: New Engines: 557 or 572
I would highly suggest 4.375 stroke. I have built 1600 horsepower with a PSI on carbs and gas. A 557 will handle 6800-7200 RPM with ease.
