Hi-po SS 454 May 27th, 06, 6:21 PM http://www.mortec.com/bbc.htm mr May 27th, 06, 7:01 PM It is probably #3999289.... Paintbug May 27th, 06, 11:07 PM How about 3963512 Mortec shows it for a 70 to 76 but I get conflicting results on other sites. mr May 28th, 06, 7:44 AM Chevrolet by the numbers 1970-75 shows block #3963512........and says...... Production of this block began Oct.1968 and continued through the 1971 model year...... It was used in 1969 as a 427 block, 1970-71 as a 454 block.......Don. Paintbug May 28th, 06, 9:28 AM Thanks guys that answered my question. pdq67 May 28th, 06, 10:00 AM Post back the letters that are at the end of the VIN number string that should be on the little deck pad that's above the pass. side top water pump bolt IF the block hasn't been decked. They decode what the block started life out as! Something like "CTX" or "TSC" sorta letters.. pdq67 | ||
