318>390 Stroker.......Your thoughts

I ran the eddies OOTB on a 360 based 410. Managed a 12.4? I had no issues, but I have heard that the guides can be tight on them if they are new. Also the springs that come on them are barely good enough for the advertised lift number from Edelbrock. Add a quick ramp and you can get some instability. I have been running a 4” cast Scat crank with the 360 journals. I shift at 6400 and cross the stripe a 6700. That crank owes me NOTHING, but at this point I’m a little scared to chase more power. I’m at 425 at the crank according to the calculators. For me the cost difference from cast to forged is not big enough to to buy a cast crank. (Your side of the world could be very different)Especially if you plan on spinning it. Plus I know no matter what I going to hammer on anything I build. My Scat cast crank was checked and balanced to 1/2 gram during a piston change 3-4 years ago. It was still straight after 7-8 years of hammering on it.
