My bad.. I used to have a '71 Merc Marq with the 429..was a real good beater, but sold it after highschool cuz I was stupid. Book for it said it had 11.5:1 (or 11.3 to 1- can't remember) compression and hadta have 99.8 octane fuel. I sold the car for 150 bucks
to a guy who wanted it for its "good heads" for a car to build for the local dirt track, which was in its infancy at the time. They won lots of races, and I kicked meself in head e'er time they did..
L8r, bought a '73 Merc with a 429 - 4V in it - thought I'd enjoy some o' the same benefits..but found out it was a pig. (You all
are aware of what I wasn't - that the 73 sucked).
Make a long story short - what should I do to make the '73 comparable to the ol' '71? (I believe in laws of physics - I'm sure after reading a little on these pages that nothing too simple can make up for smaller valves and choked ports, along with all the sickening things FoMoCo did to the monster. But I am on a budget - so be gentle)
I'm currently driving an 88 Merc with a sick (comparitively) 5.0L EFI - I know - I know, a lot can be done there, too, but some day, I may wanna put that revamped 429 into the 88. Save the fuelie for a neat Model "T" or sumthin fun like that...
