I bought a 429 Thunderjet 4V with a C6 transmition out of a old ford truck for 300 dollars it runs. I do not know any thing about the 429 could someone help. My daughter wants to put it in her '74 Rancheo and drag race on the weekends good idea or to much HP. My other kids race a '74 El Camino with a High Perofrmace 350 and a '65 Impala 4Dr SS I do not know much about a ford.The only numbers I could find is listed below

DOVE-A on the heads?
DOAE-9C485 on valve cover on Drive side?
These numbers were on the intake maifold behind the carb.
4 DOVE-9435-B
F4 9J151

Could anyone tell me what these mean.

Thanks
