Re: engine swap
I suggest finding the source of the oil before going to the extreme of trying to fit in the 454. Look at spark plugs, is it one cylinder or all? How is compression? Even, or one or more out of balance? I have never seen a motor pump actual liquid oil out the tailpipe, especially with no evidence of where it is coming from. I have done changes like the 454 idea. The famous statement at the start is "I could just swap" but then when you get into it, too deep to back out, flat wallet, reality sets in. We have a farm shop here that is more fully equipped than most repair garages and still have to work hard to make it happen too often. How did the motor run when parked? Was it that bad then? If not, find and fix the problem.
