470 Stroker - Anyone built one?
The cam is plenty big enough to make 550 in a 470. We just shipped out a 416 SBM with that same cam, light port cleanup on a set of SBM RPM heads and it made 520hp.
But we're not talking small blocks Mike...lol
The two examples of 470s you cited both have solid roller cams and larger/better port heads. Which Victors were they on the 600hp one? Std or MW port? Do you have a dyno example of a B wedge with a similar cam and the stock RPMs that mde that kind of power?
I'm sure you wanted an example of possibilities, but the examples given have a
lot more cam, and
a bit more port volume.
There's not enough overall port volume or flow to the RPM port within that cam's sweet spot to make those kinds of figures. The Victor heads outflow the RPMs by around 10-20cfm in the .400-.500 lift range and are 90ccs larger OOTB.
As for what I would expect out of that cam - I'd expect to see it peaking around 500-510
at best given the heads and intake with a mild torque curve and bigger torque numbers. With Edelbrock's valve job, average machining, parts as listed, etc - probably closer to 490-500.
Ported I could see them doing it. Not in out of the box shape.
