Hey Richard, Talk about a shoe horn fit! I was worried about the clearances of the starter, oil pan, headers, and of course the shock towers. Someone said there are L-Shaped cut outs in the towers in order for a 427 to fit in a 67/ 68. Seems to me when you put your foot to her you would end up with a dent in the tower.I guess the 302 or 351 is looking better all the time..Thanks for your time and info.R.W.
