Yes, it is the drivers side that is tight. I also used stock exhaust manifolds off a 77 gmc 1/2 ton 454. A little grinding like previous thread stated, but pretty minor. Back plug wire is snug also. I'm sitting on stock 350 motor mounts in the stock location. My truck is a 70, so it has the throttle rod instead of cable. If i think of more i will post it.
