value of a 1969/70? 429 engine?

so i have a 1969 or 70 429 engine. it came out of a ford van and was running when i pulled it year or so ago and has been garage kept since. it has all accessories except the carb (friend talked me out of it) and also has a set of brand new hooker headers. so how much is this thing worth?

i had gotten it to go into a 1970 merc. cougar that i was supposed to be gettin but with the people trying to renagotiate half way thru my part of the deal and money looking tight i'm half tempted to sell the motor and wash my hands of this project.

i've tried lookin online but i cant seem to pull up any reasonable answers so if any body could give me a ball park figure of what i can expect to get then it would be greatly appreciated. thnx.

If you can find the right buyer it could be worth upwards of $1000. Maybe $1500 if you can demonstrate that it runs. The problem with an engine of this year is that it doesn't have hardened valve seats so it can't be run on unnleaded. An advantage of an engine of this vintage is that it doesn't have a computer and all of the sensors, hence it would be good engine to swap with a minimum of hassles. Appearance is everything. Clean it up and paint the block Ford blue and use a high temperature coating for the headers. Run an ad in your local paper under parts and accessories. If it looks really good, ask $2000 for it.
