I guess I should first give a description of what I have...a z6 w/ hf manifold, t-25, greddy profec b-boost control, b&m command flow FPR, vortec FMU (hate it), RC 310 injectors and missing link (also junk). I was running 5 psi and blew my engine. I have about a 1000 to spend on some parts and i was thinking i need to put it into the block...i already have a port and polished head but its not on the car, didnt want to run into trouble and wreck it on the worn out stock block. Im just wondering what i could do to prevent a blown motor in the future and push a little more boost. I do have a chipped p28 with a chip burner and full conversion harness, innovative wideband and datalogging software to tune the vechile after the rebuild. I just need some help on what i should do for the block??? I am a mechanic and have full access to equipment and a machine shop, free of cost. I have a full understanding of engine rebuild but its been a while since i have been on a mill. If you could help me out it would be much appreciated.
