615 low deck!
 
What do the internet experts (like myself) think?

Does shafiroff know something we don’t?

I'd guess it would have to be a 6.385? What ever combo I'd like to see one tore down after numerous dyno pulls assuming parts aren't scattered throughout. Pistsons side lode etc... yikes but I have no real world experience so I can't honestly say. I grew up with to many old school builders I guess but there still in business after 40 years.

I can assure you parts are not scattered all over the place after a few dyno pulls. This is not a new combo for Shafiroff. Been around several years and makes big horsepower!

rods are probably shorter. At 6.385 the pin would be in the dome

Make note I said several not a few. Regardless no dig at Scott or his engines/company at all and know they've been around for many years with very few mostly pity complaints/issues. Does the equation work out to a std 6.135 rod? I didn't do the math but with that bore and stroke just took a stab at it. Nothing in that combo seems right in my head when I see all the potential concerns but NOTHING makes sense to me these days. Lol.

I see there has been more and more of the large CI taking it to a how new level over the last (which is now actually several years). Why not push the limits... Just not that combo for me as all.
