Many people that put the big block transplant in thevsoitba small block have that same problem with the drivers valve cover. Many I seen gently massage the firewall with a hammer to make room for the cover. Because the other problem is you can’t get the cover off to make adjustments to the valves after it’s in either. I had to hammer the firewall back when I did the hei distributor change from the stock small cap points dizzy. Otherwise you’d have to move forward the engine mounts and redrill the holes for the crossmembers. Otherwise you’d need a custom engine mounts and still redrill the trans crossmember to move the engine forward. The problem will be then how much room you have in front of the radiator and what cooling fans you use.
