Save your pennies. I always wanted a big block 429 Mustang. Nice car.

Is your 429 a 4 speed or automatic?

That body style is one of the least desirable ones, so i'd say it would be relatively cheap for an old mustang. 5-10k depending on how bad somebody wanted one. Thats just my opionion though.

Just take it to a classic car appraiser and have everything documentend. THEN ask how much its worth.

A Mach was not a high production car so depending on options and condition it could be worth a nice wad of dough, or it not much over a stock mustang.

if i knew back in 1994 what i know now i could have made a lot more money when i sold my 73 mach 1, but if i could go back i wouldn't have sold it at all. if the guy who sold it to me in 1988 knew all this then he would have wanted A LOT more for it instead of giving it to me for a steal. though mine was just with the 351 cleveland. no big block.
