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
