| ok food for thought,i rember reading old hot rod periodicals that nhra let some 427's that were sleeved down to 428 bore ,run stock because of the wieght gain difference,in the cj class mustang,i think hubert platt was one of them,i also heard there was some diff in the pan rail width,427 was narrower?i was also told the 428 non reenforced block was approx 40 lbs lighter,the 428 cj,390 reenforced block was 20 lbs lighter,then i heard stories on a427"G" block?and then i heard stories about,the cooling tunnel at the casting plant to control some stuff in the curing,cooling process,the why does ford have that N on the heavier case rear housings,while then i seen the reenfored gear case whithout the N,then what does the N or nodlar realy mean,then i heard of gray iron blocks,frying pan grade iron block,that wore the bores out too fast,example,my 76 f 250 was wore out in less that 2 years,(14000)milesand it was called back for that prob,but i had dropped in a 66 mec 390 in by then,can any one explain? |
