I'm dipping into my body-and-paint money to strengthen the lower-end on my 440...which I SHOULD have done back in 2005...when I had it re-built! I went with reconditioned,and bushed, LY factory rods,mated to Diamond forged pistons,and reconditioned factory forged crank. After getting the Eddy heads cnc-ported and milled .060,I'm estimating about 600-620 hp at the crank. I shift between 62-6500 rpm,and trap approx. 67-6800 in the 1/4. Please give me your suggestions. H-Beam or I-Beam? I'd like to keep the price to $500.00 or less. THANKS in advance! Randy B.
