'78 was detuned via compression, valve overlap by camshaft design and more + quite a bit for emissions but still tough as all get out. Aluminum or altered intake you'll be sorry. Do as you want it's your car. Owned the first high compression, pre-smog 460 4V in a Continental (1969) that was a very powerful engine and needed it as it weighed about a ton more than this Mercury, T

It's fun to dream of just bolting on HI PO parts and doing 7 sec 1/4's . Alas ,time to wake up . A carb like a demon is part of a matched system , pistons (changing ratio of compression), cam , indexed cam gear, Intake and exhaust. All had to match up in ablility. Of couse you still had to throw in porting and polishing , dergreeing the cam , recurving the dist, Multi angle valve jobs. Rejetting the carb was so tricky , NASCAR used to give teams a whole day to do this before a race. THe list goes on and on and on............. LIFE'S SHORT GO FISH
