We did this on my 70 Z28! The second gen is has proven to be a challenge cause the door opening is very close to the wheel opening & it causes the lines to pull up.. On my 70 we have it pulled 1 inch on one side & 2 inches on the other side.. We were able to fit a 335 with the 2 inch pull Post pics tomorrow!
Mini-tubs have their place and keep the car clean looking, but this gives the car a little more muscle and visual interest. Well done, I want to see a Bandit era Trans Am stretched with 335's.
