Cylinder wall thickness
By Rob - 07/26/2002 11:50:02 AM; IP 128.255.81.30
Need to pick some brain power/experience out there. I am proposing to build a 428 block into a 450-500 HP motor and perhaps add nitrous (700HP?). I plan on using a FE block with three finger webbing and a bore of 4.13 or .30 over. Motor will go into a 69 Mach I with a C-6. I have seen several great posts and read in archives about cylinder wall thickness and sonic testing. I am considering using a 428CJ or 361/391 block. Is requiring a minimum cylinder wall thickness of .150 on all walls the smart way to go? I currently have a 361 block but the sonic test shows that even with off center boring I will have at least one area of a cylinder wall between cylinders of about .120 or .115 after boring.

Please provide any experience you have that I obviously don't have. Thanks in advance!
