I have now cracked my second iron block. What are you guys running that makes big power reliably? I'm running somewhere around 800-850RWHP on boost only on the car but want to go more power later. Right around 23PSI usually but have gone up to 29PSI a time or two. This is now the second block that has cracked. This time was cylinders 7&8. Last time a couple years ago I found it cracked on all cylinders on bank 2 and got another iron block and had it machined. Probably only have 2000 miles on this block.
Current setup is iron block, Oliver rods, MMR pistons, stock heads/cams, on a Haltech 2500 ECU
