John Summers kicks butt at Grayrock
Beachtruck, I have a 69 wag with the buick 350. Currently that 350 motor is on a stand right next to a buick 455. I believe the 455 is about a 1/2 inch wider at the top of the valve covers than the 350. The 455 is longer of course but I don't think you will have any problems. It will be close but it should fit. I'm going to go home and tinker with the duece tonight. I'll double check the width on both motors and post if I was mistaken. The only way this would be different is if the frame horns on the m715 are offset differently than a wag. Not sure about that but I will look tonight...
