Crank
Scat Cast Steel 3.48

Rods
Scat 4340 I Beam 7/16 cap screw
rated 700 HP.

Pistons
Probe FPS -20.3CC Pistons.

Shooting for 10-15 psi of boost. Lets here some opinions. This will be a street car on lower boost most of the time. I dont wanna spend 700+ on custom pistons either. Hows this for a budget build?

 

the stock crank will be fine, no need to buy the scat.
Otherwise, looks fine.

i am using h-beams and speed pro powerforge pistons -21.10

 

Yup, with those rods, your stock crank is perfect. I would be willing to be the stock crank is as good if not better than the scat/eagle cast cranks...

 

Looks good, I would go forged crank or stock.. no need for another cast one.

 

They want 90 to regrind this one I have and the aftermarket one is about 160.

In my head Im still debating H beam or I.

 

From the info gathering I did you are better off with a stock one than an aftermarket cast.

Also no point in doing a forged crank if its not a 4 bolt main.

 

But his stock one is jacked up. He NEEDS a crank or has to pay to machine on the stocker

 

Going to have to pay to have the replacement one machined to fit too, just a thought.

Oh and as far as the 4bolt required for a forged.... I disagree but there isn't enough evidence for an argument about it.

 

Just machine the stock crank
Go with Eagle H beam rods, they won't cost you much more

 

Okay. Anyone try the ebay H beams?

 

I wouldn't be too concerned with 'I' vs 'H'. Aren't they, for the most part, a cross section rotated 90 degrees; and we're talking tensile and compressive loads.

 

Whats your bottom end consist of? Im not questioning your comment, Im just curious.

 

Stock crank and rods with ARP hardware

Sweet! Thats my plan as well.

 

Thats what my build turned into as well stock rod and crank with speed pro pistons, still trying to find good rings.
