I am getting my parts list together for my 385 stroker. I am going forged due to using high compression (~14:1) and E85, but will never go power adder with boost or spray, and keep the RPM's sub 68-6900. I already have SRP pistons, and will use Scat I-beams.

I see that Ohio Crank has some cheap priced forged cranks, and was looking at the 5140 forged crank as a possible option. Does anyone have any experience with these, I would like to keep costs down on this build if I can.

 

From what I have Heard they are good cranks, but wait for some others to chime in.

 

If your turning 68-6900 rpm with 14:1 compression i would not go 5140 I would go 4340 fo the added strenght because 5140 cranks usually arnt rated for much over a cast crank and I have not heard of a single failure of an Ohio crank. scat I beams might not be up to the task for a build like yours

 

Id suggest going with H-beams

A couple years ago, their quality control was HORRIBLE. Sizing was way off, journals tapered badly. A lot of them needed a LOT of heavy metal to balance right.

For cheap forged stuff, I would probably stick with SCAT or Eagle. And hell, even their QC isn't good.(At least my crank wasn't ).

Do a lot of measuring on whatever piece you buy.

 

Well the pistons I have are for 5.7 rods, the Scat Pro-comp rods should be strong enough, the RPM will probably be under 6800, as is mostly a street car with occasional road course/autox.

I was curious about the 5140 crank if it would be strong enough, the 4340 is not much more expensive if it is necessary.

 

If you are buying a lower end offshore crank, SCAT is definitely the one to consider.

Lots of big HP guys running them.

 

Probably with a lot of work in them. lol

 

Apparently things have really turned around there and they have really got the ball rolling.

 

I have heard lots of good things about them and will be using one in my next build.

 

If that's true, then it's good to hear!

 

I have an Ohio crankshaft in my current motor. Came highly recommended by my builder. No complaints or problems.
