351w Swap In A 68

[bmxmon]

I believe everything is the same except the 351w is taller. The 68's could come stock with a big block, so you should be ok as far as clearance goes. Oil pan is different, as mustangsplus shows two different parts for a 302 and 351w. MP shows the same part number for the flexplate, as long as its the same balance. If you have the entire 351 I dont really see you having any problems, might have to get some different headers if you are running them. Good luck, im sure others will chime in, as personally I've never swapped a 351 for a 302 before.
