With most kits, each brand will do Cast or Steel cranks, and I or H Beam rods, in any combo you like, so a Cast crank, and I beam rods, will be the entry level.
A friend with a Cortina, ran mid 9's in his street car, with a 393ci cast crank and H beams (scat).
My crank is steel, with H beams (Scat). Crank, Rods & Arias forged pistons was $3300 when I built it.
I would put Scat & Eagle on the same level, and World, Ford, GM, Roush (and all the other crate engine people) will use 1 of the 2, you'd hope!!).
Back in the days, when you could only buy a new crank from places like Lunati, Sonny Bryant etc, and they were about $3000+ on their own, Pro-Stroke did a roaring trade, mixing and matching cranks & rods, like Clevo 378ci kits, are an offset ground clevo crank with narrowed 6" Chev rods, and custom pistons.
What do you plan on doing with the car? Racing it?
Do you have an engine builder, or are you doing it yourself?
