Engine current config:
X Block, 4.1 Bore, 3.915 stroke, 6.4 MGP Rods, Good roller, ported W2 heads, single plane manifold, 950 Holley.
In my upgrade I will need new pistons and rods. Have not selected pistons, for rods I have a new set of steel Lentz 6.2" rods, and a set of C&A 6.125 Alum rods. Which would you use??
Would it be best to go ahead and stroke futher with a 4.250 stroke crank for a 440ci or stay with the 413ci and upgrade with pistons and rods??
Will go with new cam also but have not decided which grind.
Would you go with the Lentz rods or the C&A alum rods??
Thanks, Max

Looks to be a race car so I would use alum rods. I tune a 406 cuin sb and that made 711 to the rear tires on pump gas with 15lbs of boost. So how much hp are you looking for. With those cubes you can make 1000 with the right supercharger.

I'd go with the steel rods ( I did anyway ). I went with "Icon" IC982KTD step dish pistons which neted me 8.9 CR @ 0 deck and 60cc chambers. Had Comp grind me a solid blower cam #CRS6055/6056S at 114 lsa. Had ProSystems convert my 950 to a blow through. Good luck with your build  .
